Taka, commonly known as Koba-san, holds the title of Japan's foremost treehouse architect. With a portfolio comprising approximately 250 treehouses, his creations vary from backyard whimsies to a significant project in response to the 2011 tsunami, and even a jungle perch offering views of Angkor Wat in Cambodia (featured in a Japanese lottery commercial). His repertoire includes treehouses designed for affluent Chinese clients and those crafted for preschools, catering to parents concerned about their children's disconnection from nature.

Fourteen years ago, Biotop’s owner asked Kobayashi to build a small treehouse. Now he’s returned to rebuild it on a slightly larger scale, the idea being that cafe patrons might even eat their lunch there. [...]"
