Are you familiar with doburoku, a rare type of Japanese sake?
Unlike regular sake, doburoku is made by bottling the unfiltered mash (moromi) while fermentation continues. This makes it very difficult to store, and it's rarely served at restaurants.
Yamane Brewery handcrafts this precious sake in small batches. It may be the only sustainable brewery in Japan operating out of a repurposed convenience store.
While most breweries use stainless steel tanks, Yamane uses traditional wooden barrels made from local Nishikawa timber. This rare method allows natural microorganisms to thrive, adding unique flavors from the wood and water—resulting in a one-of-a-kind sake every time.
During the tour, you can taste three types of this special sake using locally crafted cups made from 100% Hanno soil, a material no longer produced and only available in limited quantities.
Hanno is just an hour by train from Tokyo, with easy access to Chichibu, Kawagoe, and attractions like Moominvalley Park.
