A first look at Hiroshima

Spend an unhurried day around Peace Memorial Park, then pair the castle grounds with Shukkeien on another outing. The castle keep is closed to visitors; its moat-side views and other open areas still make a worthwhile walk.

What this means for packing

Milder days make the riverside and garden pleasant walking choices. Pack a light jacket for mornings and evenings and keep an umbrella handy.

Choosing a season

The best-season badge suggests months for general sightseeing, using the typical daytime temperatures and rainfall in our monthly guides. Beach holidays, festivals, winter sports and northern lights trips may suit different dates.

Climate methodology

Broad planning ranges rounded to roughly 2°C either side of Hiroshima’s 1991–2020 mean daily maximum (23.7°C) and minimum (14.9°C) for October. JMA records mean monthly precipitation of 109.2 mm. These city-station normals are not forecast limits or a prediction for your dates; check the forecast before travelling.

Transport guide

Getting around Hiroshima

Use Hiroden’s English route information and MOBIRY TRAVEL’s mobile route search for city journeys. Choose tickets by their actual network coverage: streetcars, JR trains, buses and ferries do not share one universal pass.

  • Hiroden — official English routes and riding guidance

    Check the line number, destination and current station guidance before boarding. Use the official route map and riding instructions, especially when changing between a tram, bus and JR train. Route information does not buy or activate a ticket.

  • MOBIRY TRAVEL — mobile route search and digital passes

    Use this official mobile website without installing an app. It offers route search and supported digital tickets. Register and verify your email before purchase. The 8- or 24-hour streetcar product covers Hiroden electric rail lines; it does not include JR, buses or ferries. Other products have their own coverage, so check each planned leg.

  • MOBIRY TRAVEL — activating and showing a ticket

    In My Tickets, select the ticket under Before Activation and follow Activate when starting use, as directed for your product. Show the live ticket screen to the crew when getting off. Internet access and a charged phone are needed; screenshots are not valid. Check validity before activating and avoid starting a timed pass long before your first ride.

  • MOBIRY DAYS — separate official payment app

    Follow the official iPhone or Android download links if you want this separate registered stored-value system. Register and add credit, then scan the app’s current QR code when boarding and leaving supported services. This is different from showing a MOBIRY TRAVEL pass. Coverage is limited to participating operators; do not assume it pays JR fares or works on every bus. Use the mobile website and cash or operator-supported alternatives if app installation or registration does not suit.

  • MOBIRY DAYS — participating operators and routes

    Check this current operator list before relying on the payment app. It is not the same as the coverage of a MOBIRY TRAVEL sightseeing pass; confirm each route and any exclusions.

Check the operator’s current service notices and ticket instructions before travelling.
