The YouTube channel Dentan has shown a Daihatsu Atrai camper van converted into a Japanese-style room. An igusa rush mat was laid in the cabin; the material naturally regulates humidity and keeps the interior cool in summer and warm in winter. For more comfort, the owner suggests thick tatami mats or modular tatami, along with a bamboo table and wooden accessories. He reads and eats dessert in the evening and cooks pork soup on a gas burner in the morning. The video presents an accessible way to create a Japanese atmosphere in a compact camper van without major modifications.
