What shoes should you pack for Hiroshima?
Comfortable sneakers that slip on and off easily. You remove shoes at temples, many traditional restaurants and inns. Clean socks matter for the same reason. On Miyajima, grip helps on the trails up Mount Misen.
What do people wear in Hiroshima?
Neat, casual clothes. Japan leans tidy and understated, and very revealing clothes stand out. At the Peace Memorial Park and museum, dress respectfully. Remove shoes where you see a step up or slippers at the entrance.
What should you pack for a day trip to Miyajima?
Water, comfortable shoes and a light layer. The ferry ride is short, but walking the island and climbing Mount Misen takes time. In summer, bring sun protection and a towel for the humidity.
What plugs does Hiroshima use?
Japan uses Type A and B sockets at 100V. US plugs fit, and most phone and laptop chargers handle 100V fine. UK, EU and Australian visitors need an adapter. Many sockets are two-pin only, so three-pin US plugs may not fit.
