Places to seeWhere to go in Hiroshima
Start with the first of these. Each is worth half a day.

Hiroshima has two things almost everyone comes for, and they are half an hour apart.
Start with the first of these. Each is worth half a day.
One is a shrine gate standing in the sea. The other is a park in the middle of the city.
On the island of Miyajima, the great gate of Itsukushima Shrine stands in the water at high tide and on wet sand at low tide. You can walk out to it when the sea has gone. Deer wander the streets of the village. It is a ten-minute ferry, and it is worth staying until the day trippers have gone.
Getting in: Hiroshima Airport · Hiroshima Station (shinkansen) · about 1h 40m from Osaka
Pick the season first and the days will arrange themselves.
Cherry blossom on Miyajima in early April, with the deer under the trees. The best season here.
