Hiroshima is a compact food city with one genuinely hard table and a lot of easy, wonderful ones. That balance makes it ideal for a focused 48 hours: win a single reservation, and the rest of the trip falls into place around oysters, okonomiyaki, and a short ferry to one of Japan's most photographed shrines.
Before you go — the one booking
The anchor is Kisetsu Ryōri Nakashima, the only three-star restaurant Michelin found in Hiroshima — a husband-and-wife kaiseki counter of fourteen seats, one 18:30 seating, a single course at ¥24,250 including tax and service. Slots open online only weeks ahead and go quickly. Book this first; the itinerary below assumes it lands on Day 1.
Day 1 — the counter night
- Afternoon. Start at the Peace Memorial Park and Museum — sober, essential, and central. Walk the riverbanks afterward to reset.
- Late afternoon. Coffee and a first okonomiyaki as a snack: the Hiroshima style layers batter, a mound of cabbage, and noodles, griddled and stacked rather than mixed.
- Evening. Dinner at Nakashima. One seating, one course, no private rooms since the 2015 refit — just the counter and the season.
Day 2 — the sea and the shrine
- Morning. Ferry to Miyajima to see the great vermilion torii of Itsukushima Shrine standing in the tide. Along the approach, stalls grill oysters by the shell and fold anago (sea eel) into rice.
- Midday. Oysters are the point in the cold months — the Seto Inland Sea grows most of Japan's farmed oysters, at their best from roughly October to March. In summer, lean on anago-meshi instead.
- Evening. Back in the city, a proper okonomiyaki hall — a multi-floor building of competing griddles — sends you off well.
Getting there, realistically
Hiroshima is about 85 minutes from Osaka by shinkansen and roughly four hours from Tokyo. The only thing to plan hard is Nakashima's short booking window; the oysters and okonomiyaki look after themselves. If you want a second Japanese food city on the same trip, our 48 hours in Kanazawa pairs naturally — another compact town that eats far above its size. Tell us your dates and which night matters, and we will time the counter for you.
