There are brochures in Russian at the entrance, you can take them. It's not very interesting inside, but it smells nice of wood. For the sake of "visiting an iconic place" (and very beautiful from the outside), it's worth going. But in general, it is worth visiting not only the castle, but also to walk through its gardens. 4 hours is enough for both the castle and a walk through the gardens around it
The largest surviving feudal castle in Japan, Himeji-jo (Castle of the White Heron) is a majestic structure of bright white color. It looks very beautiful from afar, especially in clear weather, starting from the train station, and appears majestically up close. Inside, a tour of the six floors of the castle. The interior is nothing special, everything is in the ascetic style of the Japanese military aristocracy. As well as in small castles. Himeji has recently undergone restoration for several years, and its left wall is still being restored. But this is not a reconstruction, as with Osaka or Nagoya Castle (although I like the latter), the castle was not destroyed either during the Meiji Revolution or during World War II. This is just an improvement in appearance, the replacement of some materials and parts.
