Today is a self-guided day.
After breakfast take some time in the morning to do a bit of independent exploration before catching the bus back to Tokyo.
Suggested Self-Guided Itinerary:
Kubota Itchiku Museum
This museum is dedicated to Itchiku Kubota the man who spent his life practising tsujigahana, one of the techniques of shibori (tie-dyeing) in which a small bunch of cloth is tied with string before dying to make the patterns. Discover some of his signature kimonos hanging on wooden bars reflecting the natural light that comes from the sun. Even the museum itself can be considered as a great artwork, with some of its pillars made from century old cypress trees and its ceiling open so that the visitors can clearly see its wooden structure.
Kawaguchiko Museum of Art
A museum that houses temporary exhibitions of Japanese and foreign modern artists as well as a small permanent collection of paintings and photographs featuring Mount Fuji.
Saiko Iyashi no Sato Nenba
A tiny village with around twenty thatched roof houses that serve as traditional handicraft studios, museums, local restaurants, and cafés.
Alternatively take a boat ride on the lake, or ride the Kachi Kachi Ropeway to an observation point near the summit of Mount Tenjo from where Lake Kawaguchiko and Mount Fuji can be seen (during a clear day).
Head back to Kawaguchiko Station to catch the bus back to Shinjuku in Tokyo.
