Simose Art Museum 下瀬美術館

This was one of THE most beautiful museums I've been too, which makes sense because it was named one of the world's "Most Beautiful Museums" via the inaugural Prix Versailles (the UNESCO architecture award) in 2024. It's a bit further out from the main part of Hiroshima city (it's in Ōtake, Hiroshima and we got here by car), and the area it's situated in feels a bit random, but the whole space was such a beautiful experience with views of the Seto Inland Sea.
