Route Briefing: London to Hiroshima
Few routes carry as much emotional weight as the journey from London to Hiroshima. You're travelling roughly 9,500 kilometres to a city that has transformed one of history's darkest moments into one of humanity's most powerful messages of peace — and that contrast alone makes every hour of the roughly 16-and-a-half-hour journey (with a stop in Tokyo) feel worthwhile.
Japan Airlines and ANA are your most reliable options, both routing through Tokyo Haneda before the short onward connection to Hiroshima Airport. British Airways operates a codeshare arrangement via Tokyo as well. If you can be flexible with your travel dates, aim to book three to six months ahead and favour mid-week departures — you can realistically shave a meaningful amount off the standard fare, which typically sits between £950 and £1,250. Snag it under £700 roundtrip and you've done very well indeed.
Timing matters enormously here. Late March to early April brings cherry blossom season, when Hiroshima's Peace Memorial Park becomes almost unbearably beautiful — pale pink blooms framing the skeletal Atomic Bomb Dome in a way that feels both heartbreaking and hopeful. July and August are peak summer, busy and humid but alive with festivals. For a quieter, more contemplative visit, autumn delivers spectacular foliage and comfortable temperatures without the crowds.
From Hiroshima Airport, buses connect directly to the city centre, making arrival straightforward. Once in the city, the tram network is genuinely excellent and covers most of the key areas you'll want to reach. The Peace Memorial Museum is essential — not easy, but essential — and the surrounding park deserves several unhurried hours. Then there's Miyajima Island, a short ferry ride away, where the famous floating torii gate of Itsukushima Shrine rises from the sea at high tide in one of Japan's most iconic images.
Don't leave without eating okonomiyaki. Hiroshima's version — layered rather than mixed, stacked with noodles and cabbage and cooked on a griddle in front of you — is fiercely distinct from the Osaka style, and locals will happily tell you theirs is superior. They're probably right. The neighbourhood around Okonomimura, a multi-storey building dedicated almost entirely to this dish, is a brilliant place to spend an evening.
The practical tip worth remembering: pick up a Suica or Icoca card at Tokyo's airport during your connection. It works on trains and trams across Japan, including in Hiroshima, and saves you fumbling for change or navigating ticket machines every time you move around the city.
