Takasho U400 Unit House

Takasho U400 is an eight-tatami unit house sold by Ai Ryutsu as a made-to-order new building for hobby rooms, garages, pet rooms, small offices, shops, or secondary living space. The 5 m by 2 m footprint gives about 12 m2 of enclosed area, enough for a compact private room with furniture or work equipment. The listing positions the model as a flexible small building rather than a site-only hut. Ai Ryutsu also handles transport and installation work, so the purchase can be paired with placement support in the Kanto area. It is best suited to buyers who need a finished room module without commissioning a full custom building.
