For those of you who, like me, worship all things Nipponese, check out the Japanese Castle Browser.
Each castle is classified a variety of ways... example:
Bitchu Matsuyama Castle
- Castle Type: Mountaintop Castles
- Condition: Original
- Historical Value: Important Cultural Property
- Rating: 4 Stars
- Visit: Viewer Donated
- Destination: Hiroshima
And you also get several pictures of the architectural wonder in question. Go culturize yourselves!
