Buddhism had influence on architects and Samurai
So the architects made the old temples and houses with wood, and then they planned a garden inside the complex. This garden was for contemplation and recreation. The other gardens with fruits, vegetables were located elsewhere and not all old houses had gardens only for contemplation. The structure of the traditional japanes house with the garden as extention of the living room was only possible and made only sense because of the mattresses, on which they sat and because of the climate. Everything was planned around the seatings. Wisdom, experience, logic, creativity.
