Perfect One-Day Itinerary: Osaka to Hiroshima & Miyajima Island (Complete Guide with Transportation Tips)
Japan's Kansai area is known as a place rich in history and culture, centered around Kyoto and Osaka. Furthermore, there are many unique tourist destinations in the surrounding areas, with countless attractive spots that make you want to stop by. Among these, Hiroshima has been particularly visited by many foreign tourists in recent years.
This time, we'll introduce an itinerary to maximize your enjoyment of Hiroshima in one day, departing from Osaka. With this guide, you can efficiently and deeply experience Hiroshima's charm. Please fully enjoy Hiroshima's history, beautiful scenery, and delicious food.
How to Get to Hiroshima from Osaka?
There are mainly two transportation methods from Osaka to Hiroshima: Shinkansen and express bus.
The Shinkansen takes approximately 1 hour and 30 minutes from Shin-Osaka Station to Hiroshima Station. Since this is the fastest way to travel, it's ideal for those who want to use their time effectively. If you have a Japan Rail Pass, you can use it without additional charges, so please take advantage of it.
On the other hand, express buses take about 5-7 hours from Osaka Station to Hiroshima Station. While it takes longer compared to the Shinkansen, the fare is very reasonable at around 3,000 to 7,000 yen.
If you use an overnight bus, there's also the benefit of saving accommodation costs while traveling.
Choose Shinkansen if you prioritize efficiency, or express bus if you prioritize cost.
Hiroshima's Attractions
Hiroshima is a charming city where rich nature, culture, and deep history interweave.
For example, Itsukushima Shrine, which appears to float mysteriously on water, captivates visitors.
Hiroshima is also known as the city where the world's first Atomic Bomb was dropped. The Atomic Bomb Dome and Peace Memorial Museum make us deeply contemplate the value of peace.
Furthermore, Hiroshima's unique food culture is also attractive. Local dishes using regional ingredients such as okonomiyaki and oysters should become a major pleasure of your trip.
Hiroshima, where history, nature, and gourmet food are condensed, brings emotion and deep learning to visitors.
Route Overview of One-day Itinerary from Osaka to Hiroshima
In this plan, we travel from Osaka to Hiroshima by Shinkansen.
After arriving at Hiroshima Station, first head to Miyajimaguchi Station on the JR Sanyo Line. Transfer to a ferry and cross to Miyajima Island, where the World Heritage site Itsukushima Shrine stands.
On Miyajima Island, tour historical buildings and enjoy walking around the town while savoring Miyajima's specialty street food.
In the afternoon, return to Hiroshima city and visit the Atomic Bomb Dome and Peace Memorial Museum.
Afterwards, return to Osaka by Shinkansen, ending a fulfilling day.
One-day Itinerary to Savor Hiroshima's History, Traditions, and Cuisine
8:00AM: Departing from Osaka
When departing for Hiroshima, board the Shinkansen from Shin-Osaka Station. Please note that Shin-Osaka Station is a different station from Osaka Station.
It's recommended to purchase Shinkansen tickets in advance. Especially during early morning hours and weekends, seats fill up quickly, so securing them beforehand gives peace of mind. If you have a Japan Rail Pass, you can reserve seats on Shinkansen trains like "Hikari" and "Sakura" for free.
Furthermore, delicious breakfast is essential for the start of your journey. Various Eki-ben are sold inside Shin-Osaka Station. Eki-ben refers to bento sold at stations. Many contain regional ingredients and local cuisine, and enjoying them while viewing the scenery from the shinkansen is one of travel's great pleasures.
Arrive at the station a little early and look for Eki-ben that catches your interest.
9:30AM: Arrival at Hiroshima Station / Direct Train to Itsukushima Shrine
From Hiroshima Station to Itsukushima Shrine, take the JR Sanyo Line to Miyajimaguchi Station. The travel time is approximately 25 minutes.
From Miyajimaguchi Station, take a ferry to Miyajima. Two companies operate ferries: JR and Miyajima Matsudai Kisen, and the JR ferry accepts Japan Rail Pass.
The ferry ride takes about 10 minutes, and from inside the boat, you can see Itsukushima Shrine's Grand Torii Gate gradually approaching.
10:30AM: Visit "Itsukushima Shrine," registered as a UNESCO World Heritage Site
Itsukushima Shrine is located on Miyajima Island, one of Japan's representative scenic spots, and was registered as a UNESCO World Heritage Site in 1996.
The magnificent shrine buildings standing in the sea and the approximately 16-meter-high Grand Torii Gate standing in front create a mystical sight as if floating on the water's surface. This view is counted as one of the Three Views of Japan.
This shrine is worshipped as a guardian deity for maritime safety and fishing, and many people still visit for prayers today. While experiencing the history and culture of Itsukushima Shrine, please feel Japan's traditional aesthetic sense.
Itsukushima Shrine is a special shrine that shows different expressions depending on the tides
The greatest attraction of Itsukushima Shrine is that its expression changes dramatically depending on the tides.
At high tide, the shrine buildings appear to float on the water's surface, and the Grand Torii Gate also shows its magnificent form standing in the sea. During this time, a mystical sight like a painting unfolds, leaving many tourists breathless with its beauty.
On the other hand, at low tide, you can walk right up to the base of the Grand Torii Gate. Looking up at the Grand Torii Gate from close range, you'll be overwhelmed by its size and power. Observing the details of the torii gate that can only be seen at low tide and the shells beneath it is also an enjoyable experience.
The time when the tide is high differs depending on the season
The tides at Itsukushima Shrine vary greatly depending on the season and day. Before visiting, please check the tide table. You can obtain tide tables from the official website or local tourist information centers.
As a rough guide, there are the following trends:
- Spring (March-May): High tide often occurs in the morning or evening, low tide around noon
- Summer (June-August): High tide often occurs in the morning or at night, low tide in the afternoon
- Autumn (September-November): High tide often occurs during the day, low tide in early morning or evening
- Winter (December-February): High tide often occurs in the afternoon, low tide in the morning
However, these are just general trends, and they actually fluctuate daily. By planning according to the tides, you can enjoy sightseeing more efficiently.
Depending on the tides, consider switching your morning and afternoon plans
While this itinerary schedules a visit to Itsukushima Shrine in the morning, depending on the tides and the "desired view" of the Grand Torii Gate, it may be better to visit in the afternoon.
If you want to see the Grand Torii Gate floating on water on a day when morning is low tide and afternoon is high tide, we recommend switching with the scheduled Hiroshima city sightseeing in the afternoon and visiting Itsukushima Shrine in the afternoon instead.
Please check Miyajima's tide table in advance and adjust your itinerary according to the desired view of Itsukushima Shrine.

11:30AM: Visit two shrines worth visiting together with Itsukushima Shrine
After touring Itsukushima Shrine, please also visit two attractive shrines and temples in the surrounding area.
Both have different atmospheres from Itsukushima Shrine, and you should be able to feel Miyajima's history and culture more deeply.
Hokoku-jinja (Senjokaku Pavilion)
Hokoku-jinja is a shrine characterized by a large building called Senjokaku Pavilion.
Although it remains unfinished to this day, from its open space you can overlook Miyajima's townscape and the Seto Inland Sea, with wonderful scenery spreading out.
The building has many pillars inside and has an open structure where wind blows through pleasantly. When I visited in summer, I was very soothed by its coolness and sense of openness.
While being a historical building, it has a somehow approachable atmosphere, and visitors spend time here leisurely. Senjokaku Pavilion is a recommended spot where you can enjoy Miyajima's history and scenery simultaneously.

Daishoin
Daishoin is a temple located at the foot of Mount Misen, which towers behind Itsukushima Shrine, and has the oldest history on Miyajima.
The highlight is the Ichigan Daishi statue in Mani-den, which is said to grant one wish. I actually went to make a wish there myself, and the clear air and peaceful atmosphere, as if the wish was quietly being received, was very impressive.
Daishoin is a place where you can feel the depth and history of Buddhism, different from Itsukushima Shrine. It's definitely worth extending your visit a little from Itsukushima Shrine. I recommend it for those who want to spend time quietly surrounded by rich nature.

If you want to experience Miyajima's charm to the fullest, getting guided by a local guide is recommended.
The appeal of this tour is that the guide provides detailed explanations about Miyajima's history and culture. By hearing about the stories behind Itsukushima Shrine, you can gain deep understanding that cannot be obtained through mere sightseeing.
Also, enjoying local street food while having local experiences not found in guidebooks is a major point.
This is recommended for those visiting Miyajima for the first time or those who want to tour Miyajima efficiently.
However, there are many slopes and stairs, and you'll be walking for long periods, so it's not suitable for those with concerns about their legs and back or those not confident in their physical strength.
Meeting point: In front of Coin Operated Locker at outside of JR Miyajimaguchi Station

12:45AM: Enjoy Food Walking Along Miyajima Omotesandō Shopping Street and Machiya Street
After finishing your visit to Itsukushima Shrine as part of your day trip itinerary from Osaka to Hiroshima, let's enjoy some food walking around the area.
Omotesandō Shopping Street is lined with many souvenir shops and restaurants. On the other hand, Machiya Street is a quiet street where traditional old houses stand in a row.
While strolling through the atmospheric townscape during your Hiroshima excursion, try to discover hidden cafes and shops that make this destination a perfect addition to any Osaka to Hiroshima travel itinerary.
Momijido Main Store

When visiting Miyajima on your day trip from Osaka, Momiji Manju is absolutely unmissable. Momiji Manju is a confection with sweet bean paste filling inside sponge cake batter shaped like maple leaves, and it's one of Hiroshima's representative souvenirs. Momijido Main Store is a long-established shop known for its history and quality.
In particular, the "Age Momiji (Deep-fried Momiji Manju)" - fried Momiji Manju - is exquisite with a crispy outside and fluffy inside. Since you can eat it with one hand, it's perfect for food walking during your Hiroshima sightseeing. I also make sure to eat fried momiji every time I visit Miyajima.
It's sure to be appreciated as a souvenir from your Osaka to Hiroshima journey, so please be sure to stop by.

Pettara Pottara Honpo

If you want a unique food walking experience in Miyajima during your day trip itinerary, I recommend "Pettara Pottara" from Pettara Pottara Honpo.
This is like okonomiyaki-style mochi made by steaming Miyajima's famous oysters and conger eel mixed with glutinous rice, then grilling it with special sauce.
The outside is fragrant and the inside is chewy, packed with the umami of oysters and conger eel. With one bite, the aroma of the sea spreads throughout your mouth, allowing you to savor the unique taste of Miyajima that makes this destination special for tourists traveling from Osaka.
Since it can be eaten casually, it's perfect when you get a little hungry during your Hiroshima exploration. For those who want to try Miyajima's unique B-class gourmet food during their day trip, this is definitely a shop you should visit.

Miyajima Cuillere Italian Restaurant

"Miyajima Cuillere Italian Restaurant," nestled in the back alleys of Machiya Street, is a shop renowned for its sandwiches and sweets - a delightful discovery for tourists on their Osaka to Hiroshima adventure.
Here, sandwiches made with homemade bread are particularly recommended. They use plenty of carefully selected seasonal ingredients, and the beautiful cross-section is characteristic. With one bite, the taste of the ingredients spreads throughout your mouth. I was also moved by the beauty of its appearance and the harmony of flavors.
Since takeout is available, on nice weather days, I also recommend enjoying it picnic-style with the spectacular view spread out in front of you, adding a memorable moment to your day trip itinerary.

Anago Meshi is one of the must-try specialties when visiting Miyajima.
Among these options, Miyajima Anago Meshi Mametanuki is a shop that serves specialty conger eel rice with dedication - a must-try for anyone following an Osaka to Hiroshima travel route.
Anago Meshi consists of rice topped with conger eel that has been fluffy grilled with secret sauce, characterized by its fragrant aroma and deep flavor. At Mametanuki, you can taste conger eel rice that uses carefully selected conger eel and is carefully prepared. The rice absorbs the umami of the conger eel, and with each bite, you'll feel happy - truly representing the culinary highlights that make Hiroshima a perfect day trip destination from Osaka.

3:00 PM: Visit the "Atomic Bomb Dome" which retains its appearance from that time
Return to Hiroshima city and visit the Atomic Bomb Dome.
The Atomic Bomb Dome is a building that miraculously survived and retained its form after withstanding the heat rays and blast of the atomic bomb dropped on Hiroshima on August 6, 1945. Its shocking appearance is an important historic site that conveys the horror of nuclear weapons and the tragedy of war to the present day, and it is also registered as a UNESCO World Heritage Site.
When I first witnessed the Atomic Bomb Dome with my own eyes, I was so shocked that I was left speechless.
Visiting this place will surely serve as an opportunity to never forget the tragedy of war and to deeply consider the importance of building a peaceful future.
The reason why the Atomic Bomb Dome is preserved in its original state
The Atomic Bomb Dome is deliberately preserved in its near-collapsed state to convey the devastation of the atomic bomb to future generations.
After the atomic bomb was dropped in 1945, it was decided to preserve it due to the strong wishes of many people who believed that "the horrors of war should be conveyed to the world and it should remain as a symbol of peace."
The Atomic Bomb Dome is not merely ruins. It is a silent witness that continues to speak of the inhumanity of nuclear weapons, the folly of war, and the strong desire for peace.
This building will undoubtedly continue to speak to people's hearts as a lesson for not letting the memories of war fade and for aiming toward a world without nuclear weapons.
What you can do at the Atomic Bomb Dome
The main purpose of visiting the Atomic Bomb Dome is to understand its historical significance and think about peace.
Although you cannot enter inside the building, you can walk around it and observe it from various angles.
Multiple information boards explaining the situation at that time are installed in the surrounding area. By reading these information boards, you can deeply learn about the circumstances when the Atomic Bomb Dome was bombed and the subsequent history of its preservation. I also felt the preciousness of peace anew while reading these explanations.
Photography is possible, but it is important to understand the meaning of the place and act with respect. The Atomic Bomb Dome is an important place for not forgetting past tragedies and using them as lessons for the future.
4:00 PM: Tour the Peace Memorial Museum to view war-related materials and exhibits
After touring the Atomic Bomb Dome, I strongly recommend visiting the adjacent Peace Memorial Museum. This museum aims to convey the full extent of the damage that the atomic bomb brought to Hiroshima, and displays belongings of atomic bomb victims, photographs, and records from that time.
The interior is structured so that visitors can systematically learn about Hiroshima before the atomic bomb was dropped, the devastation immediately after the bombing, and the subsequent path to reconstruction. In particular, the testimonies of atomic bomb survivors and the belongings they left behind have an impact that cannot be expressed in words.
The museum's exhibits convey to us the horror of nuclear weapons and a strong message that such tragedies must never be repeated. Please take time to carefully observe the exhibits and think deeply about peace.
If you want to understand Hiroshima's history more deeply, we recommend sightseeing while listening to explanations from local guides. By participating in tours, you can experience deep learning and emotion that cannot be obtained by simply looking around.
The greatest attraction of this tour is that guides provide detailed explanations about the stories behind the Atomic Bomb Dome and Peace Memorial Park, and the experiences of people at that time. You can feel the subtle nuances that are difficult to understand just by reading materials, and the feelings of people who live locally.
Especially for those who are not very familiar with historical background, the presence of guides with specialized knowledge should be very reassuring. It's perfect for those who want to think deeply about peace and learn.
Tours depart on time. If you are more than 15 minutes late, you cannot participate, receive a refund, or change the schedule, so please arrive with plenty of time to spare.
Meeting point: In front of the mont-bell store near Nishi Kamiyacho Station
Tour area: Hiroshima city
Start time: 10:00~
5:00PM: Visit the "Peace Memorial Park" built with hopes for eternal peace in the world
After visiting the Peace Memorial Museum, let's take a stroll through Peace Memorial Park. This park is a place built to commemorate the victims of the atomic bomb and to wish for eternal peace.
Throughout the spacious grounds, various memorial monuments and memorials are scattered, enveloped in a solemn and quiet atmosphere. The lush green park serves as a place of relaxation for citizens, but at the same time, it is also a place that quietly appeals for the importance of peace. Take your time to walk slowly through the park and offer prayers for peace.
The feelings embodied in Peace Memorial Park
Peace Memorial Park is not just an ordinary park. It is a place filled with strong wishes for eternal peace - to comfort the souls of the victims of the atomic bomb dropped on Hiroshima and to ensure that such tragedies are never repeated again.
At the center of the park, there are places with messages of peace, such as the Peace Flame where flames continue to burn and the Children's Peace Monument. At each location, you can feel the tragedy of that time and the feelings of people who wish for peace.
By visiting here, you should be able to deeply understand the horrors of war and engrave the preciousness of peace in your heart once again.
What you can do at Peace Memorial Park
First, please put your hands together at the Cenotaph for the Atomic Bomb Victims in the center of the park and offer prayers for those who became victims of the atomic bomb. Nearby, you can also see the "Peace Flame" that continues to burn with wishes for nuclear abolition.
Also, at the "Children's Peace Monument," colorful Orizuru (paper cranes) are sent from all over the world, visually conveying the feelings of people who wish for peace.
Orizuru were continuously folded by a girl who suffered from leukemia due to atomic bomb aftereffects while praying "may I get well," and in Japan, they are known as symbols of peace and wishes. People who empathized with that story continue to send Orizuru even now.
Each place should serve not just as sightseeing, but as an opportunity for you to think about the meaning of peace.
Let's also visit Hiroshima Orizuru Tower
Hiroshima Orizuru Tower is a popular place as a facility where you can experience folding Orizuru with wishes for peace.
On the top floor of the tower, there is an observation deck where you can overlook the cityscape of Hiroshima, and you can see not only the Atomic Bomb Dome but also Hiroshima Castle and the Seto Inland Sea.
What I especially recommend is the "ORIZURU WALL" inside the tower. Here, you fold Orizuru yourself and drop them into a glass wall. The sight of Orizuru folded by people from all over the world with wishes for peace being displayed across the entire wall is very moving. I also folded Orizuru here and wished for peace.
Hiroshima Orizuru Tower closes at 6:00 PM, so please be careful about the time you visit.

Optional Time: Departure toward Osaka
Before returning to Osaka, it's good to make time to have dinner at Hiroshima Station or in the station building, or to purchase souvenirs. There are many items that will become travel memories, such as Hiroshima specialties like Okonomiyaki and Momiji Manju.
Also, if you have time to spare, I recommend having a light drink around the station. There are many shops where you can enjoy delicious local sake and craft beer.
However, please be careful not to miss the last Shinkansen. The last Shinkansen runs relatively late, but it's safe to check the schedule in advance just to be sure.
If You Have Time to Spare, Enjoying Hiroshima's Exquisite Food and Bar Hopping is Also Recommended
If you have time to spare, enjoying exquisite food and bar hopping in Hiroshima at night is also recommended.
The charm of this tour is that guides take you to deep local bars and izakayas in Hiroshima. You can taste delicious food and drinks unique to Hiroshima at local shops that would be difficult for tourists to enter on their own.
Also, being able to experience Hiroshima's culture and daily life through interaction with local people is one of the big attractions.
It's perfect for people who want to experience Hiroshima's food culture while interacting with local people.
Note that anyone 15 years old or older can participate in this tour, but according to Japanese law, only people 20 years old or older can drink alcohol.

3 Recommended Tourist Spots You Can Incorporate Into Your Itinerary According to Your Preferences

Hiroshima Castle is a beautiful castle built around 1589 by Terumoto Mori, who ruled the land of Hiroshima. It was once destroyed by the atomic bomb, but was rebuilt in 1958 to its current form.
This castle is also called "Ri-jō." "Ri-jō" means "Carp Castle," and as the name suggests, many carp swim in the moats around the castle, delighting visitors.
The inside of the main keep is a museum where you can learn about the history of Hiroshima Castle and the life of samurai.
It's especially recommended for history lovers and those who want to experience the beauty of Japanese castles.

For access to Mount Misen, the ropeway is convenient.
From the ropeway's Shishiiwa Station to the summit, you need to walk for about 30 minutes. However, along the way there are many attractions called the Seven Wonders of Misen, such as the Eternal Flame and Kuguri-iwa Rock, which never runs dry even during droughts.
It's especially recommended for those who want to enjoy hiking in nature and those who want to view magnificent scenery.
