Tsukuba Mom: Geospatial Information Authority (国土地理院 kokudo chiri in)

My son's favorite facility is Geospatial Information Authority. It has a building which we can visit for free. The building name is "The science museum of map and survey (地図と測量の科学館 chizu to sokuryou no kagakukan)". He likes the 2nd floor, it has computers that he can play some games based on the geography. Unfortunately, they are in Japanese, so I'm wondering children from other countries can enjoy it or not, but try it~! I like the shop on 1F, it sells many geographical goods, like books, maps, memo pad, towels, pens.. They are very interesting. My second son likes playing outside, there are white earth-model, and old airplane that was used for geographical survey and taking air photo. It is good place to wile away Sunday afternoons.
