After the Peace Memorial Park we went to see the Castle of Hiroshima. The castle was originally built in wood and thus got burned down by the bomb. Now its main tower has been reconstructed in concrete. The tower houses a few exhibitions, some of them permanent. All exhibitions had been translated into English except the most interesting one, the one on traditional toilets. I loved the cute cats on the poster for the exhibition.
When Japan opened itself up to the west for merchants in the 19th century, they brought a really good blue color to Japan. This Prussian Blue was far better than the stuff that they had been using and so artists got really into it (e.g. used in The Great Wave off Kanagawa). So, in the exhibition there was a really cool porcelain toilet with Prussian Blue decoration. It looked like an oversized old-fashioned soup pot.
There was also a really neat model of a palace, where I had a lot of fun trying to figure out the layout of the thing, imagining which rooms had served which purpose.
