Hiroshima is a three-day city that turns into a four-day trip the moment you look properly at a map of the Inland Sea. Three days is enough to give the Peace Memorial Park the morning it needs, hand Miyajima a full day and a night, and still leave an afternoon for the castle grounds and a garden. The fourth day is what buys you the sea itself, either a naval museum in Kure or the temple hills and bicycle bridges of Onomichi. Two days is not enough, and the people who try it tend to spend both of them on trains.
But the number of days matters less here than the order, and Hiroshima has one unusual constraint that ought to decide the whole shape of your trip: the Peace Memorial Museum opens at around half past seven in the morning. Almost nothing else in urban Japan does. It is the one major site you can reach before the coaches arrive, and it is also the one you should not attempt tired, hungry, or at the end of a long day of sightseeing. So it goes first, on the first morning, before anything else. Everything below is arranged downstream of that single decision.
Day One: The Park, Read in the Order It Was Built
Book ahead if you can. At the time of writing the museum reserves its first hour for visitors who have booked online through the official site, which makes it both the quietest slot of the day and the hardest to get at short notice. If you miss it, turn up at opening anyway. The difference between half past seven and ten in the morning inside the main building is the difference between a room you can stand still in and a slow-moving queue. Admission is modest, somewhere around 200 yen for an adult. The East Building's historical section feeds into the main building's testimony and artefacts, and ninety minutes is the minimum that makes sense. Two hours is more honest.
Then walk out and read the park in the direction it was designed to be read. Kenzo Tange laid the whole composition on a single axis: standing at the arched cenotaph you look straight through it, across the Flame of Peace, to the skeleton of the A-Bomb Dome on the far bank of the Motoyasu River. That sightline is the argument of the entire park compressed into one view, and it only works from the museum side. Take the Children's Peace Monument and its glass cases of folded cranes on the way north, then cross the river to the Dome itself and walk a full circle around it.
If you want more, the National Peace Memorial Hall for the Atomic Bomb Victims sits underground between the museum and the cenotaph. Entry is free and it is almost always quiet: a circular hall of names, and a library of survivor testimony you can actually sit down with. It is the part of the park most visitors walk straight past.
Then stop. The afternoon of day one should be deliberately lighter, and stacking another heavy site onto that morning is the error we would most want to talk you out of. Lunch first. Nagata-ya sits a short walk from the north end of the park and cooks Hiroshima-style okonomiyaki, the layered kind with noodles pressed into the middle, for somewhere in the region of 1,000 to 1,500 yen. Expect a wait at peak lunchtime.
Afterwards, walk north along the river to Hiroshima Castle, about twenty minutes at an easy pace, and adjust your expectations before you set out. The main keep closed permanently in March 2026: the 1958 reinforced-concrete reconstruction no longer met earthquake standards, and the city has said that whether it is rebuilt in timber or retrofitted remains undecided, with any rebuild decades away. What is still open justifies the walk. There is the moat and the grounds, the Ninomaru gate and turrets rebuilt with traditional joinery in the early 1990s and open to walk inside, Gokoku Shrine in the middle of the compound, and the Sannomaru complex of shops and food that opened along the approach in 2025. Go for the grounds, not the tower. If the day has run short, this is the thing to cut.
Evening belongs to Hatchobori and Nagarekawa, the eating and drinking quarter east of the park. Micchan Sohonten's Hatchobori branch traces its line back to a post-war street stall from 1950 and is widely credited with the noodles-inside format that became the city standard; it typically closes on Tuesdays, so check before you walk over. The alternative is Okonomimura in Shintenchi, a building holding roughly two dozen okonomiyaki counters stacked over several floors. It is chaotic, genuinely local, and the easiest place in the city to eat late.
Day Two: Miyajima, and the Case for Sleeping There
There are three ways across and they are not equivalent. The Hiroden tram, line 2, runs all the way to Miyajimaguchi for the flat fare of about 240 yen but takes something like seventy minutes. The JR Sanyo Line covers the same ground in roughly half an hour. And then there is the boat almost nobody books: the World Heritage Sea Route leaves from a pier a short walk downriver from the A-Bomb Dome, runs down the Motoyasu and Honkawa and out into Hiroshima Bay, and lands on Miyajima in about forty-five minutes. Expect around 2,000 yen one way, reserve the day before, and take it if you are only making this crossing once. Arriving at a shrine built out over the water, by water, is not a small thing.
From Miyajimaguchi, two competing ferry companies run the ten-minute crossing at roughly 200 yen each, plus a Miyajima visitor tax of around 100 yen collected on arrival. Take JR outbound: its sailings between roughly nine in the morning and about four in the afternoon swing in close past the great torii, which the Matsudai boats do not, and the JR ferry is covered by the Japan Rail Pass. If you are riding trams and ferries all day, the combined Hiroden one-day pass costs about 1,000 yen and folds the visitor tax in.
Now the part that actually governs the day: look at a tide table before you choose your hour. At high water the corridors of Itsukushima Shrine stand over the sea and the torii floats. At low water the bay drains and you walk out across the flats to stand underneath it. These are two entirely different places, neither of them the correct one, and you cannot have both inside a five-hour day trip. That is the whole argument for staying the night.
Order on the island: shrine first, before the mid-morning boats land. Entry runs about 300 yen, or roughly 500 with the Treasure Hall included. Then climb the short rise behind it to Senjokaku, the vast unfinished hall of bare pillars that Hideyoshi never completed, with the five-storey pagoda standing beside it. Then Daisho-in, about fifteen minutes uphill from the pier and free to enter, worth the climb for the spinning sutra wheels set into the stair rail, the cave of hanging lanterns, and the hundreds of small stone rakan figures scattered up the slope.
Mount Misen above it is a genuine mountain rather than a viewpoint. The ropeway climbs in two stages and costs somewhere around 1,800 yen one way or 2,500 return, running roughly from nine in the morning until late afternoon with seasonal variation and occasional maintenance closures, so confirm it before you build a day around it. It also does not reach the top: from the upper station it is a further half-hour walk with a descent and a climb in it. Be aware, too, that Reikado, the hall near the summit that housed a flame Daisho-in says has burned since Kukai lit it nearly twelve centuries ago, and from which the Flame of Peace in the park was kindled, burned down in May 2026. The temple's monks saved the flame itself and a rebuild is planned, but the hall is not there at present.
Eat on the island, or just off it. Omotesando, the covered shopping street running up from the pier, grills oysters in front of you and sells momiji manju hot off the iron; oyster season proper runs roughly November to March, and Kakiya is the long-standing name on that street. For anago-meshi, the grilled conger eel laid over rice cooked in its own broth that counts as the local dish, Ueno beside Miyajimaguchi station on the mainland has been at it since 1901. Expect around 2,000 to 2,500 yen for a set, and there is a bento counter if you would rather eat it on a bench.
Then stay. Iwaso, in the maple valley of Momijidani, and Kurayado Iroha near the pier are the two names that come up most often, and ryokan rates mean a real step up from a Hiroshima business hotel, usually with dinner and breakfast included. What you are buying is the hour after the last ferries leave: the shrine lit, the deer wandering emptied streets, the arcade shuttered, and the island handed back to its residents.
