Hiroshima Travel Guide: Peace, History, and Okonomiyaki

Hiroshima is a city of 1.2 million people that was rebuilt from near-total destruction. On August 6, 1945, the United States dropped the first atomic bomb used in warfare directly over the city center, killing an estimated 70,000 to 80,000 people immediately and a further 90,000 to 140,000 by the end of 1945 from radiation and injuries. Today, Hiroshima is a modern, functioning city — evidence of a deliberate and ultimately successful reconstruction — with the Peace Memorial Park and Museum at its center serving both as a record of the bombing and as an ongoing argument for nuclear disarmament.

The city has more to offer than its history: Hiroshima-style okonomiyaki is one of Japan’s great regional dishes, the castle and traditional gardens are well-preserved, and Miyajima island — with the floating torii gate of Itsukushima Shrine — is among the most photographed places in Japan.

Getting to Hiroshima

The standard route from Tokyo is the Tokaido-Sanyo Shinkansen. The Hikari service takes approximately 4 hours from Tokyo Station for ¥18,340 and is covered by the JR Pass. The Nozomi — the fastest service at 3 hours 50 minutes for ¥19,080 — is not covered by the JR Pass. From Kyoto, the journey is 1 hour 40 minutes by Hikari for ¥10,490. From Osaka, 1 hour 30 minutes for ¥9,720. From Fukuoka (Hakata), 1 hour by Sakura for ¥5,940.

Within Hiroshima, the city tram network covers the main attractions, with a day pass (¥700) covering unlimited tram travel. The Peace Memorial Park is approximately 20 minutes by tram from Hiroshima Station.

Peace Memorial Park and Museum

The Peace Memorial Park occupies the area closest to the atomic bomb’s hypocenter — the point directly below the detonation. It is a 12-hectare green space containing a series of memorials, the museum, and the Atomic Bomb Dome.

The Peace Memorial Museum (¥200) is the most important museum in Japan for understanding the human consequences of nuclear weapons. Entry tickets and guided tours of the Peace Memorial Park can be booked in advance through Tiqets — useful during the peak March–May period when morning queues build at the main entrance. The exhibits are organized chronologically: the city before the bombing, the bombing itself, the immediate aftermath, the medical effects of radiation exposure, and the ongoing advocacy for nuclear disarmament. Personal items belonging to victims — a child’s lunchbox, a wristwatch stopped at the moment of detonation, a burned school uniform — are displayed with individual stories. The museum does not editorialize heavily; it documents, and the documents are sufficient.

Allow 2 to 3 hours. Many visitors find the experience emotionally draining and benefit from time in the park afterward. The museum is open from 8:30am to 6:00pm (7:00pm July and August, 5:00pm December and January). Admission is ¥200 for adults.

The Atomic Bomb Dome (Genbaku Dome)

The Genbaku Dome — the ruin of the former Hiroshima Prefectural Industrial Promotion Hall — is the only structure near the hypocenter that remained standing after the bombing. Its steel-ribbed dome and exterior walls survived because the bomb detonated almost directly overhead, and the downward blast pressure was distributed rather than horizontal. The building was preserved deliberately as a monument. Entry to the exterior is free; the ruin is visible from the riverbank at all times.

Standing before the dome — the skeleton of the building visible through the gaps in the walls, the iron framework of the dome silhouetted against the sky — is an experience that no amount of photographs prepares you for. It is one of the most affecting places in Japan.

Hiroshima Castle

Hiroshima Castle (¥370) was built in 1589 by the warlord Mori Terumoto and served as the seat of Hiroshima’s feudal lords until the Meiji Restoration. The original castle was destroyed in the atomic bombing; the current five-story tenshu (keep) is a concrete reconstruction completed in 1958. The interior houses a museum covering the history of the castle, Hiroshima’s feudal period, and samurai equipment and armor. The castle grounds include reconstructed turrets and earthworks that give a good sense of the original scale.

Shukkei-en Traditional Garden

Shukkei-en (¥260) is a traditional Japanese landscape garden designed in 1620 by Ueda Soko, a disciple of the tea ceremony master Sen no Rikyu. The garden is organized around a central pond with islands, bridges, and miniature landscapes intended to evoke famous scenic spots of China in miniature. Koi swim in the pond, and the surrounding plantings are designed for year-round seasonal variation: cherry blossoms in spring, irises in June, autumn maples in November. The garden was severely damaged in 1945 and has been carefully restored.

Hiroshima Okonomiyaki

Hiroshima’s signature dish is okonomiyaki — a savory pancake that differs substantially from the Osaka version. In Hiroshima-style okonomiyaki, the ingredients (batter, mountains of shredded cabbage, bean sprouts, thinly sliced pork belly, a portion of cooked noodles, and a fried egg) are layered and cooked sequentially on a flat iron griddle rather than mixed into a batter and poured. The result is a taller, denser, more structurally complex pancake. It is finished with okonomiyaki sauce, mayonnaise, dried bonito flakes, and dried seaweed, and served directly on the griddle surface.

Okonomi-mura (“okonomiyaki village”) is a three-story converted commercial building near the main shopping street with 25 individual stalls, each operated by a single cook who will prepare your meal in front of you on a counter-mounted griddle. Prices average ¥800 to ¥1,200 per portion. No reservations; arrive before noon or after 2pm to avoid the lunch queue.

Miyajima Island — Essential Excursion

Miyajima (formally Itsukushima) is a 30-minute train and ferry journey from central Hiroshima. Take the JR Sanyo Line from Hiroshima Station to Miyajimaguchi (26 minutes, ¥420) and then the JR ferry to the island (10 minutes, ¥210 — JR Pass holders travel free on the ferry). The island’s floating torii gate, the historic shrine complex, and the hiking trails to Mount Misen make it one of Japan’s most complete single-day destinations. See our dedicated Miyajima guide for the full detail.

Using the Hiroshima Pass

The Hiroshima Welcome Pass (¥900 for 1 day, ¥1,100 for 2 days) covers unlimited rides on the city tram network and the Ujina Port ferry to Miyajima. It is worth buying for a 2-day Hiroshima visit that includes Miyajima. Available at Hiroshima Station tourist information.
