Outside: minus 20°C and snow as far as you can see. Inside: warm waves, tropical air, and a child who hasn’t stopped smiling for an hour.
The Question Every Parent Has
Planning a Hokkaido winter trip with young children raises an immediate concern: what do non-skiers do all day? What happens after skiing, when legs are tired and patience is thin?
Mina-Mina Beach answers both questions completely.
1. Mina-Mina Beach: Japan’s Largest Indoor Wave Pool
This isn’t a standard hotel pool. Mina-Mina Beach is Japan’s largest indoor wave pool — open year-round regardless of season or weather outside.
Glass greenhouse design Floor-to-ceiling glass walls and ceiling mean you’re swimming while looking out at snow-covered Hokkaido forest. On sunny days, natural light pours through and photographs beautifully.
Activities available (Dec 1, 2025 – Apr 5, 2026):
- Stand-up Paddleboard (SUP): Balance on the water while the waves move beneath you
- Slackline: Test your balance over the water — surprisingly addictive for kids and adults alike
Getting there: Mina-Mina Beach is near the Resort Center. From The Tower or Risonare Tomamu, take the free resort shuttle — don’t walk in winter snow.
2. Kirin-no-Yu: Open-Air Hot Spring After Swimming
Don’t head straight back to your room after swimming. Kirin-no-Yu, the resort’s open-air hot spring bath, is directly connected to Mina-Mina Beach — the perfect next stop.
What makes it special: The name means “Giraffe Hot Spring” — and the open-air setting lives up to the poetry. You’re genuinely in the forest, soaking in hot water while snow falls around you.
- Winter contrast: Head cold, body warm — the classic Japanese winter onsen experience at its most pure
- Nighttime: Stars visible above, snow silent around you, water steaming — a moment that’s hard to describe and impossible to forget
- Family-friendly: A calm space for conversations with children that somehow feel more meaningful in the open air

Shuttle Bus Guide
Hoshino Resort Tomamu is large. Walking in winter snow is exhausting and cold. The free shuttle connects all resort facilities every 5–10 minutes.
- For Mina-Mina Beach: Alight at “Mina-Mina Beach” or “Resort Center” stop
- Recommended flow: Swimming → Kirin-no-Yu onsen → Shuttle bus back to room. This order keeps wet hair inside as much as possible — important in sub-zero temperatures.
Checklist Before You Go
- Swimwear: Bring your own, especially for children. Rental available but children’s sizes are limited
- Towels: Provided at both the pool and onsen — no need to carry from your room
- Route planning: Pool → Onsen → Shuttle is the most efficient and warmest sequence
Bonus for 2026 visitors: Starting January 2026, “Hokkaido AVANT” opens — a Finnish-style sauna with the option to dive into an ice lake immediately after. Not for the faint-hearted, but unforgettable.
Hoshino Resort Tomamu in winter isn’t just about skiing. Mina-Mina Beach and Kirin-no-Yu together create a full day of warmth, activity, and genuine rest — even when everything outside is frozen.
For families planning a Hokkaido winter trip, this resort isn’t optional. It’s the destination.
