Yunoyama Onsen Green Hotel
湯の山温泉 グリーンホテル
An inn at the foot of Mt Gozaisho in 1,300-year-old Yunoyama Onsen, proud of its own spring gushing 500 litres a minute. It insists on free-flowing source water, constantly refreshed, and the viscous alkaline simple spring is known as 'beauty water'. The big open-air bath opening onto the mountains through the seasons is the draw, especially in autumn colour. Day-bathing prices were cut in July 2026 for the inn's 60th anniversary: adults ¥700 on weekdays, ¥800 on weekends and holidays, children ¥400/¥500; open 10:00–19:30 (last entry 18:30), closed Fridays. Lunch (makomo udon and more) and day kaiseki plans with bathing are offered, and it pairs easily with the Gozaisho Ropeway or Aqua Ignis. About 10 minutes by Mie Kōtsū bus from Kintetsu Yunoyama-Onsen Station; about 20 minutes by car from Yokkaichi IC; 150 parking spaces.

500 litres a minute, Yunoyama’s biggest flow — a hotel’s great rotenburo overflowing with two springs
Yunoyama Onsen Green Hotel is a rarity in Yunoyama Onsen — said to have been opened in 718 — in having two springs on its own grounds, and since opening in 1969 it has boasted the largest flow in the resort: 500 litres a minute rising at 45.2 °C from 1,300 metres down. That abundance allows 100 % undiluted source water to overflow the tubs continuously, so fresh water is always pouring in and the freshness and concentration never drop. There are four baths: the Gensen-buro, filled with source water as it comes, hot and with a faintly toasty, broth-like scent; the spacious Hisui-no-yu bath hall; the large rotenburo Nagomi-no-yu ringed by mountain greenery through the seasons; and Iyashi-no-yu, a viscous, yunohana-flecked garden rotenburo added in 2008, with a drinking spout outside. The alkaline radium spring has long been cherished locally as a “beauty bath”. The building is old but well kept, and day admission was actually cut in July 2026, for the 60th anniversary, to ¥700 on weekdays and ¥800 at weekends. Mind only the limits — 10:00–19:30 (last entry 18:30) and closed Fridays — and you get an orthodox onsen that competes on sheer volume of water, a different pleasure from the polish of Aqua Ignis. Summer BBQ beer-garden plans with the rotenburo are popular too.
Tips & cautions
- Closed Fridays plus occasional extra days. Day bathing 10:00–19:30, last entry 18:30 — early.
- The Gensen-buro is hot (near 45 °C) — keep it short. Iyashi-no-yu is tepid and viscous, good for lingering.
- Sip the drinking spring sparingly.
- From July 2026: ¥700 weekdays / ¥800 weekends — ignore older listings (¥1,000).
- On foot from the station it’s a 20-minute climb — a 5-minute taxi is recommended.
- Tattoo policy unconfirmed — it’s a hotel, so ask in advance.
- Summer evenings (Jul–Sep) are busy with BBQ beer-garden plans.
- Do Aqua Ignis (¥600) the same day — comparing the two waters is half the fun.
