Hiroshima Castle’s main keep is closed to interior visitors, but the closure does not apply to every part of the site. You can still view the keep from outside, visit the free reconstructed buildings in Ninomaru during their seasonal opening hours, and consider the Ninomaru museum shop and Sannomaru area as separate visitor options.
The keep closed on 22 March 2026. Plan around the buildings and areas that remain open rather than expecting to climb the tower or visit its former indoor museum. The information below was checked against official sources on 4 November 2026; opening arrangements and future plans can change, so check the official calendar for your date.
For the rest of your stay, see our Hiroshima travel guide, Hiroshima Peace Memorial Park guide, and Hiroshima-to-Miyajima planning guide. If you want a visual preview of the setting, the Hiroshima Castle walking video by Jose Travel Experiences can help you picture the site, but use the official visitor information—not a video—for current entry details.
Hiroshima Castle at a glance
The key distinction is between the keep and the rest of the castle site. The keep’s interior is closed, while its exterior remains visible; Ninomaru’s reconstructed buildings continue to be open to visitors under seasonal hours. The shop and Sannomaru area are also listed as visitor options, but each has its own arrangements.
| Part of the site | What to expect | Entry and planning notes |
|---|---|---|
| Main keep | Exterior viewing only | Interior closed from 22 March 2026; no confirmed reopening date |
| Ninomaru reconstructed buildings | Wooden reconstructed gate and turret buildings | Free entry; seasonal hours and a last-entry deadline apply |
| Ninomaru museum shop | A separate shop visit | Seasonal shop hours; purchases are separate from free building entry |
| Sannomaru area | An area of the site still available to visitors | Check the arrangements for the specific facility you plan to visit |
The official visitor page lists the Ninomaru buildings, shop and Sannomaru as options after the keep closure. It does not make those options interchangeable: free admission to the Ninomaru buildings does not mean every facility has the same hours or entry conditions. Check the official visitor information before setting out, especially if your plans depend on a particular building or facility: Hiroshima Castle official visitor information.
A practical approach is to decide first whether you want to enter a building or mainly see the exterior and wider site. If entering a building matters, make Ninomaru your priority and arrive before its last-entry time. If you are considering the shop or Sannomaru, check their details separately rather than assuming they follow the Ninomaru buildings’ timetable.
The keep is closed inside, but visible from outside
The closure concerns entry into the keep, the main tower building. It does not mean that the entire castle site has closed, and it does not prevent you from seeing the keep’s exterior. However, you should not plan an indoor visit, a climb to upper floors, or a visit to the keep’s former museum.
The city cites deterioration of the concrete and ageing equipment among the reasons for closing the keep. Its notice gives 22 March 2026 as the closure date. Read the city’s explanation for the current status and reasons: Hiroshima City: closure and future of the keep.
This matters because older photographs, videos and guidebooks may show rooms or visitor facilities that are no longer available. A description of an indoor museum or tower view should not be treated as evidence that you can still enter. The exterior remains part of the visit, but it is a different experience from going inside.
The city’s closure information does not give a confirmed date for reopening the keep interior. Treat the closure as continuing unless official information for your travel date says otherwise. If interior access is essential to your plans, check the current official visitor page rather than relying on an older itinerary.
Hiroshima Castle history: original and reconstructed buildings
Mori Terumoto built Hiroshima Castle during the Azuchi-Momoyama period. The Fukushima family followed the Mori as castle lords, and the Asano family followed the Fukushima. The castle town developed on the delta at the mouth of the Ota River, a setting that forms part of the site’s history.
The original keep was wooden. It collapsed in the atomic bombing on 6 August 1945, and the tower visible today is not that surviving wooden structure. The current keep is a reinforced-concrete exterior reconstruction built in 1958.
The 1958 reconstruction served as a venue for the Hiroshima Reconstruction Grand Exhibition. After the exhibition, it was used as a museum. That history explains why older accounts may describe a museum inside the tower even though visitors cannot enter the keep under the current closure arrangements.
Ninomaru has a separate building history. Its public reconstructed buildings were rebuilt in wood between 1991 and 1994. Seeing wooden buildings in Ninomaru does not mean that the main keep is a surviving wooden original: the two areas represent different buildings and different reconstruction projects.
The official castle history page provides background on the site and its past: Hiroshima Castle history. Japan’s Modern Castles also has an episode focused on Hiroshima Castle and its modern building history. Use historical material to understand what you are looking at, while checking the official visitor page for what you can enter now.
Ninomaru: free reconstructed buildings and opening hours
Ninomaru is the area to prioritise if you want to enter castle buildings. The public reconstructed buildings listed there are Omote Gomon, Hira Yagura, Tamon Yagura and Taiko Yagura. Admission to these reconstructed buildings is free, but you still need to follow their opening hours and last-entry deadline.
| Visit period | Ninomaru building hours | Last entry |
|---|---|---|
| April–September | 09:00–17:30 | 17:00 |
| October–March | 09:00–16:30 | 16:00 |
The last-entry time is 30 minutes before closing. Treat it as the latest time to arrive for entry, not as a suggested arrival time; reaching the buildings at closing time is too late to enter. Check the official visitor information and calendar for the date you plan to visit.
The official calendar lists the Ninomaru reconstructed buildings as closed on 8 December 2026 and during 29–31 December 2026. These are date-specific entries in the checked calendar, not a reason to assume that the same dates apply every year. Recheck the calendar for your visit, including if you are travelling near the end of the year.
Inside the Ninomaru buildings, visitors remove their shoes. Shoe lockers are available, and you can ask reception for a shoe bag if you need one. The official instructions say to take a bag supplied at reception home after use, so follow those instructions rather than leaving it behind.
The museum shop has different hours from the reconstructed buildings. Its listed summer hours are 09:30–17:00, and its winter hours are 09:30–16:00. The shop may therefore close before the buildings do, depending on the season; check its timetable if shopping is part of your plan. Purchases are separate from the free admission to the Ninomaru buildings.
The official Ninomaru information page is useful for confirming the buildings and visitor instructions. Deep Japan By the Last Samurai also presents Hiroshima Castle and Shukkeien in a combined sightseeing video, which can help you consider the two places together without substituting for current opening information.
Planning your visit: address, map and order
The official written address is 21-1 Motomachi, Naka-ku, Hiroshima. The castle’s grounds guide provides Japanese and English maps, so you can identify Ninomaru and other parts of the site before you arrive. Open the official castle grounds guide and maps, or use Google Maps directions to Hiroshima Castle.
Because no transport route or fare is specified here, plan the journey from your actual starting point rather than assuming one mode of transport suits every visitor. In your map app, enter the castle address or select the destination link, then review the directions for your chosen starting location. If you use public transport, check the relevant operator’s current information for the service you intend to take.
Reaching the general castle location is only one part of the plan. Decide which area you want to see, use the official map to locate it, and allow time to walk to that part of the site. If entering the Ninomaru buildings is important, plan your arrival around the seasonal last-entry time rather than the building’s closing time.
A useful order is to check the calendar first, locate Ninomaru on the English map, and then set directions to the official address. On arrival, follow the notices at Ninomaru reception and store your shoes as instructed before entering the reconstructed buildings. If you also want to visit the shop, check its separate hours before you leave that part of the site.
For questions about arrangements that matter to your group, the castle lists 082-221-7512 as its contact number. Ask specifically about the building or facility you intend to use, rather than asking only whether “the castle” is open. The official grounds guide and current visitor page are the best starting points for checking the map, calendar and published arrangements.
For the wider city itinerary, read our Hiroshima travel guide. Visitors arriving from Kansai can compare options in our Osaka-to-Hiroshima guide before planning the local journey, while those combining the castle with the memorial area can use our Hiroshima Peace Memorial Park guide to plan that separate visit. Walking Archive offers a Hiroshima Castle walking tour that can help you look at the site’s setting before a visit; use official sources for the current opening details.
Future plans and common planning mistakes
As of the city’s update dated 30 September 2026, there is no confirmed reopening date for the keep interior. The city says it has no plan to demolish the present keep immediately and is continuing preliminary studies of options, including wooden reconstruction. A wooden-reconstruction policy has not been presented as decided.
The planned Sannomaru history centre is a separate project from reopening the keep. The city gives 1 June 2027 as the planned opening date for the first-floor guidance and experience areas, and 1 October 2027 for the second-floor permanent and special exhibition areas. These are planned dates, not a guarantee of future opening; check the city’s current update before arranging a trip around them.
One common mistake is treating the phrase “Hiroshima Castle is open” as confirmation that the tower interior is accessible. The keep’s exterior can still be seen, but interior entry has been closed since 22 March 2026. For an indoor building visit, look to Ninomaru’s reconstructed buildings and verify their hours.
Another mistake is using an old timetable or assuming that every facility closes at the same time. Ninomaru buildings have seasonal hours and a last entry 30 minutes before closing, while the shop has its own seasonal timetable. Check each facility you plan to use instead of applying the building hours to the whole site.
Do not treat the planned history-centre dates as current opening hours, or assume that wooden reconstruction of the keep has already been approved. The city describes a staged plan for parts of the history centre and ongoing consideration of future keep options. Tako Venture introduces Hiroshima Castle’s history; compare historical accounts with the city’s latest notices when planning what to visit.
Hiroshima Castle questions
Can I visit Hiroshima Castle after the keep closed?
Yes, but the visit is different from an interior tour of the tower. The keep’s interior closed on 22 March 2026, while its exterior remains visible. The Ninomaru reconstructed buildings, museum shop and Sannomaru area remain visitor options with separate arrangements, so check the official information for the part you want to visit.
Is there an admission charge for the Ninomaru buildings?
Admission to the reconstructed Ninomaru buildings is free. The keep interior is closed, so you cannot buy or use admission for an indoor keep visit under the current arrangements. The museum shop is a separate facility, and any purchases there are not part of the free building entry.
Can I go inside the keep or see its upper-floor view?
No interior visit is available under the current closure information. Do not plan to climb the tower or visit its former indoor museum based on older descriptions or photographs. You can still view the keep from outside and visit the Ninomaru buildings if they are open on your date.
Is the present keep the original wooden tower?
No. The wooden keep was lost in the atomic bombing on 6 August 1945, and the current tower is a reinforced-concrete exterior reconstruction from 1958. Ninomaru’s reconstructed buildings are a separate project: they were rebuilt in wood between 1991 and 1994.
When will the keep reopen?
The city’s current explanation does not give a confirmed reopening date for the keep interior. It says the present keep is not planned for immediate demolition and that studies of options, including wooden reconstruction, are continuing. The planned Sannomaru history-centre openings in 2027 are separate from any decision about reopening the keep.
What are the Ninomaru hours and last-entry times?
From April through September, the reconstructed buildings are listed as open from 09:00 to 17:30, with last entry at 17:00. From October through March, they are listed as open from 09:00 to 16:30, with last entry at 16:00. Check the official calendar for your travel date because listed closures and future arrangements can affect a visit.
What should I know before entering the Ninomaru buildings?
Visitors remove their shoes inside, and shoe lockers are available. If you need a shoe bag, ask at reception; the official instructions say to take a bag provided there home after use. Check any notices at reception on the day and follow the staff’s instructions.
Where can I find the address and map?
The address is 21-1 Motomachi, Naka-ku, Hiroshima. The official grounds guide includes English and Japanese maps, and you can use the address in your map app to plan directions from your starting point. Check your chosen transport operator separately for current service details, since the castle map is for the grounds rather than a transport timetable.
