Tosadomariura, Naruto, Tokushima
AoAwo Naruto Resort Onsen
A resort-style option for combining sea-view natural hot-spring baths with lunch or another day-use activity. The reviewed standard plans bundle bathing with food or activities rather than offering a clearly separate soak-only ticket.
Check before bathing
- Opening hours
- A confirmed 2026 day-use option combines a lunch buffet, hot spring and fishing pond at ¥5,000 per adult; a seasonal sweet-potato harvest, lunch and hot-spring plan is ¥5,500. Bath access is generally listed around 12:00–24:00, but each bath has weekday cleaning closures; access depends on the purchased plan and that day's bath schedule.
