I first came to the museum over thirty years ago, when it was in a different building. The exhibition the was quite graphic and overwhelming and really conveyed the horrific suffering, particularly of innocents. The exhibition has been toned down quite a bit which makes it more accessible in that it conveys the important message of the horror of nuclear warfare, without traumatising the visitor quite so much. If you only do one thing in Hiroshima, visit this museum

A very well-made and informative museum that gives insight into a sad chapter of Japan's history. It's certainly not an easy visit but a must-see in Nagasaki. It can get a bit crowded with tourists and school children. There's a small café with a few lunch and dessert options.

We were running out of time for the post-lunch tour. Of course, the Nagasaki Atomic Bomb Museum was tops on our list of things to do. Inside, there were many exhibits of the aftermath, but the more interesting exhibits were those showing the development of "Fat Boy" and the backroom discussions of when and where the next atomic bomb should be dropped. Kyoto was considered but, in the end, Nagasaki was targeted. Of the photos of the aftermath, the most memorable were the ones of the shadows of the victims in the sidewalk or steps where the victim was -- fascinating. Compared to the similar museum in Hiroshima, I think the one there is somewhat better.

Our main purpose of visiting Nagasaki was to see this museum and experience a slower pace in Japan (it is our 2nd visit). This museum and parkland memorials was not as fancy or perhaps as well visited as Hiroshima (which we visited previously), but still worth a visit to understand the horrific nature of the bombing. I found we could go through the museum at a slower pace and it was also less crowded - in some ways time to absorb and self reflect. Very small shop on the way out - it seems like the site is more for respect rather than making money out of tourism which is nice to see. In the parklands it was great to see the local people and others paying respects. In all, allow a couple of hours and it is an easy tram ride, but be aware it is a steep climb up the hill to get there.

Interesting and thought-provoking museum. Some good exhibits and some moving ones. In particular, the clock that stopped at 11:02, which was the moment when the bomb exploded over ground zero, where there is now a black monolith. Well worth a visit, although the atomic bomb museum in Hiroshima is better (but also much busier than this one).

A must see for anyone who likes history and is concerned about world peace. Growing up in Hawaii I learned so much about Pearl Harbor and how the attack catapulted the US into WW II. Learning more about how the war was ended and seeing what transpired in Nagasaki has given me a better appreciation for the toll war takes on civilians as well as the environment. This museum has some powerful messages. It’s not to be missed!

A very good museum, worth every minute you spend here. But if you read carefully, you will see the history presented before WW II is pretty one-sided/ incomplete. The Japanese aggressions in Russia and China prior t o 1931 are not even included. If we are to avoid the horrors of the past, we must be completely honest about what everyone did.

We visited the peace museum that commemorates the lives lost when an atomic bomb was dropped on Nagasaki. The museum was very moving and the grounds outside were beautifully maintained. When our group visited the museum itself was very crowded and there didn't seem to be any air conditioning or air circulating. Maybe this was on purpose so that visitors had a sense of not being able to breath.
