Hiroshima in 2025-2026: Events, Openings & Travel Updates

What's New in Hiroshima for 2025-2026

Hiroshima's biggest event in 2025 is the 80th anniversary of the atomic bombing, marked by an expanded Peace Memorial Ceremony on August 6. For the first time, all 196 countries and regions were openly invited to attend — a shift from the previous selective invitation system, according to the Hiroshima City official website. This milestone anniversary has drawn international attention and increased visitor numbers.

Beyond the anniversary, Hiroshima continues to operate as a major tourist destination with its established lineup of attractions and seasonal festivals. For an overview of permanent attractions, see our guide to things to do in Hiroshima. For the latest developments and what's changing for visitors, read on. Note that specific 2026 event dates have not yet been officially announced — check the Hiroshima City and Visit Hiroshima websites for updated schedules closer to your travel dates.

The 80th Anniversary Peace Memorial Ceremony

The Hiroshima Peace Memorial Ceremony (平和記念式典) takes place every year on August 6 at Peace Memorial Park. The 2025 ceremony was particularly significant as it marked the 80th anniversary of the atomic bombing.

Ceremony Schedule and Format

According to the Hiroshima City official website, the ceremony runs from 8:00 AM to 8:50 AM. The key moments:

• 8:00 AM: Ceremony begins
• 8:15 AM: One minute of silence — the exact time the bomb was dropped
• 8:16 AM: The mayor delivers the Peace Declaration (平和宣言), calling for nuclear abolition
• 8:50 AM: Ceremony concludes

For the 80th anniversary, the ceremony included additional invited dignitaries, including the Supreme Court chief justice and youth representatives from sister cities. The format change to openly announce the ceremony to all 196 countries (rather than sending selective invitations) was a significant shift aimed at emphasizing global participation.

How to Attend as a Visitor

The ceremony is free and open to the public. Seating is divided into reserved sections for hibakusha (被爆者 / atomic bomb survivors) and their families (~1,600 seats), and general public seating (~1,200 seats) on a first-come, first-served basis.

Practical details for attending:

• Arrive before 6:00 AM to secure a general public seat. The park is cleared at 5:00 AM and reopened for ceremony attendees starting at 6:00 AM.
• Security screening is mandatory — expect baggage checks and metal detectors at entry points.
• Political messages, protest banners, and related items are not permitted inside the park during the ceremony.
• Dress appropriately — modest, respectful clothing is expected. Bring sun protection, as the ceremony takes place outdoors in August heat.
• If seats are full, you can still observe from outside the restricted area or watch on screens at nearby locations.

According to GetHiroshima, Social Book Cafe Hachidori-sha screens the ceremony followed by a discussion — a good alternative if you cannot secure a seat.

Lantern Floating Ceremony on August 6

The Lantern Floating Ceremony (灯ろう流し) takes place in the evening of August 6, after the morning memorial. Approximately 10,000 paper lanterns are floated on the river near the Atomic Bomb Dome (原爆ドーム), each carrying messages of peace and remembrance. The sight of thousands of glowing lanterns drifting past the illuminated Dome is one of Hiroshima's most powerful images.

The ceremony is free to watch from the riverbanks. No ticket or reservation is needed — simply walk to the Motoyasu River area near Peace Park in the early evening. The atmosphere is quiet and contemplative. Many visitors describe it as the emotional highlight of an August 6 visit to Hiroshima.

Seasonal Events and Festivals

Hiroshima's event calendar extends well beyond August 6. Key seasonal highlights include:

Spring (March - April)

• Cherry blossom season in Peace Memorial Park, Shukkeien Garden, and along the city's rivers. Peak bloom is typically late March to early April.
• Miyajima's cherry trees bloom around the same period, drawing visitors to the island.

Summer (July - August)

• The Peace Memorial Ceremony and Lantern Floating on August 6 (see above)
• Hiroshima summer festivals and fireworks events — check Visit Hiroshima for confirmed 2026 dates

Autumn (October - November)

• Autumn foliage on Miyajima Island, particularly at Momijidani Park (Maple Valley). Peak color typically occurs in mid to late November.
• Comfortable temperatures make autumn one of the most pleasant times for city exploration.

Winter (December - February)

• Illumination events at Hiroshima Dreamination in the city center (typically late November through early January). Check Visit Hiroshima for confirmed dates.
• Fewer tourists and lower accommodation prices.

Specific 2026 event dates are typically announced several months in advance. Check the official Visit Hiroshima website for confirmed schedules.

Travel Updates and Infrastructure Changes

Hiroshima's core infrastructure for visitors remains stable. The streetcar (Hiroden) network continues to serve major routes between Hiroshima Station, Peace Park, and the Miyajima ferry terminal. The Tokaido-Sanyo Shinkansen provides the primary intercity connection.

Key points for travelers in 2025-2026:

• Hiroshima Peace Memorial Museum continues to operate — check the official museum website for current hours and admission.
• Shinkansen access from Osaka (~1.5 hours), Tokyo (~4 hours), and Fukuoka (~1 hour) remains unchanged. JR Pass holders should note that Nozomi trains are not covered by the standard pass.
• Miyajima ferry services continue as usual from Miyajimaguchi, accessible by Hiroden streetcar from Hiroshima Station.

For any infrastructure disruptions or temporary closures, check the JR West and Hiroden websites before traveling.
