I love how this narrow Nishi Azabu Juban bar is defined by the street tree out front. The bar and tree are named カクレミノ (kakuremino, or Dendropanax trifidus). The building front is largely glass and wood beam, with the tree providing some privacy and mystery. The tree has been espaliered so that it grows in barely two dimensions.
According to Wikipedia, this evergreen tree is native to lower Honshu, Shikoku, Kyushu, and Okinawa.
