Pine Tree

Tucked away on the 2nd floor of 5th Street in Shinjuku Golden Gai, Pine Tree (ぱいんつりー) is one of the rare bars in the district to offer tatami seating with a kotatsu (heated low table). The bar's own X profile sums up its spirit as "cooking, secret-base building, and hobbies" — reflecting a genuine focus on homemade food alongside drinks. Over the years, the wooden building has also hosted intimate live performances, including bandoneon evenings. Opening time is roughly 8 p.m. and closing follows whenever the sign goes dark — fully on the owner's terms. The close quarters make it easy to drop in solo, while the kotatsu setup suits small groups looking to settle in for a long winter night.
