Shishi-Iwa House (SSH), which is nestled in a nature sanctuary in Karuizawa, Japan, brought together six top chefs for a private culinary retreat last fall. The objective? To gain some inspiration and explore their creativity in this tranquil, design-driven setting. Shishi-Iwa House is a collection of three architectural masterpieces designed by Pritzker Prize laureates Shigeru Ban and Ryue Nishizawa. The unique boutique hotel is about an hour’s train ride from Tokyo.
