5 Things to Do in Hiroshima during Summer

Here are the top things to do in Hiroshima during the summer months.

1. Relax on Hiroshima’s Beaches

2. Experience Miyajima’s Summer Magic

A visit to Miyajima Island is essential year-round, but summer brings special cultural events that transform the island.

• Miyajima Fireworks Festival: Traditionally one of Japan’s most famous fireworks displays, it lights up the night sky over the iconic floating torii gate of Itsukushima Shrine, creating a spectacular seaside setting.
• Miyajima Dance Festival (Odori-no-yube): Held in August, this historic event features traditional dances dating back over 500 years, performed to ward off evil spirits.
• Kangensai Festival (July): One of Japan’s most important maritime festivals, featuring elaborately decorated boats and classical court music dedicated to the gods.

These events offer a rare chance to experience living traditions in one of Japan’s most scenic locations.

3. Enjoy Seasonal Festivals

Summer in Hiroshima is synonymous with festivals (matsuri), many of which take place throughout July and August.

• Fireworks Festivals Across the Region: From Hiroshima Bay to nearby cities like Onomichi, fireworks displays light up the coastline throughout the season.
• Toukasan Yukata Festival (June): One of Hiroshima’s major festivals and the unofficial start of summer, when locals begin wearing yukata (summer kimono).
• Hiroshima Peace Memorial Ceremony (August 6): A solemn and meaningful event held at Peace Memorial Park to commemorate the victims of the atomic bombing.

These events blend celebration with cultural reflection, offering deeper insight into Hiroshima’s identity.

4. Discover Shukkeien Garden at Night

The historic Shukkeien Garden becomes especially enchanting during summer evenings, when its carefully landscaped grounds take on a charming and atmospheric charm. During the Tanabata Festival in early July, the garden is beautifully illuminated after dark, creating a dreamlike setting that feels far removed from the bustle of the city. 

Visitors can take part in this seasonal tradition by writing wishes on colorful paper strips and hanging them on bamboo branches, adding a personal and cultural touch to the experience. For the best appreciation of the garden’s beauty, consider visiting once during the day and returning in the evening to enjoy its magical nighttime transformation.

5. Explore Nature and Outdoor Adventures

In and around Hiroshima, summer is an ideal time to enjoy the region’s natural landscapes and outdoor activities. With its proximity to the Seto Inland Sea and surrounding mountains, Hiroshima offers a variety of ways to balance sightseeing with time in nature. Whether you prefer relaxing by the water, exploring scenic hiking trails, or visiting seasonal flower fields, there are plenty of opportunities to experience a different side of the region while staying active during the warmer months.

• Water Activities & Beaches: The calm waters of the Seto Inland Sea are well suited for activities such as kayaking, stand-up paddleboarding, and swimming. The gentle waves and scenic island views make it an accessible and enjoyable environment for beginners and experienced visitors alike.
• Sandankyo Gorge: Sandankyo Gorge is a striking natural area known for its clear river, waterfalls, and forested hiking trails. The shaded paths and cooler air make it a popular destination for those looking to escape the summer heat while enjoying a peaceful outdoor setting.
• Sunflower Fields at Sera Kogen Farm: At Sera Kogen Farm, large sunflower fields come into bloom from late July through August. The wide expanses of bright yellow flowers create a vivid seasonal landscape and are a popular spot for photography and leisurely walks.

River and Waterfront Experiences: Hiroshima’s rivers, which flow through the city center, provide a refreshing contrast to the summer heat. Riverside cafes, promenade paths, and open-air seating areas offer a relaxing way to enjoy cooler evening breezes while taking in views of the water and city skyline.
