Two stories
I just googled Tateyama and Karuizawa...did not hear about these places..tfs
Karuizawa is not very famous place .. as it is more like a holiday resort for rich people during summer .. they will have their second home in karuizawa which has a pleasant climate and just two hours drive from Tokyo ..
That place is more like a cultural collaboration of japan and Europe .. the houses and the streets are designed like European cities..different from rest of the cities.
They have all the holiday games and the best of facilities in the world .. so it is a favourite place of foreign residents too..
