Seisonkaku is a villa that the 13th lord of the Maeda family built for his mother in Kenrokuen Garden in 1863. Fine techniques in a wide variety are used for the inner pillars and walls of Seisonkaku. These techniques include a wooden panel with openwork carvings of flowers and birds and a coffered ceiling for the guest chamber called "Ekken-no-ma." From these, visitors will know the status of the then Maeda family.
Furthermore, Seisonkaku exhibits articles with a long and distinguished history, such as dolls for the Japanese Girls' Festival and furniture.
