Although Kobayashi Daizo was the main carpenter, the villagers all took part in creating this historical, wooden structure. Designed by Okada Tokitaro, it was designated Important Cultural Property in 1980. Since many famous financial business men and trade merchants from all around the world would stay here, it was called “Karuizawa’s Rokumeikan” (A Rokumeikan was a popular building for social events/diplomats in Tokyo) and a dinner party would be held in this western style building almost every evening.
