Asaya Hotel (192) - Atrium-Sky Onsen & Edo-Era Flair

Two banquet halls (650 m² & 420 m²) plus eight breakout rooms flex from 60- to 600-seat layouts. A glass elevator whisks delegates from sessions to the rooftop infinity bath in 40 seconds; the hotel’s planner team can add kimono parades on the lantern catwalk for gala night.

A waterfall tumbles through a lantern-lit atrium, making nights feel like an indoor festival. Under star-filled sky, guests soak in steaming baths while cedar silhouettes frame gleaming constellations. Edo-period cosplay ice-breakers, soba-making battles and river-raft races layer “only-in-Tochigi” colour onto every agenda.
