What Family-Friendly Activities Are at Tomamu in Winter?
Beyond skiing, Tomamu offers an Ice Village, indoor wave pool, hot springs, snow play areas and English-speaking ski school — making it one of Hokkaido's best winter family resorts.
Beyond skiing, Tomamu offers Mina Mina Beach (an indoor wave pool open year-round), the Ice Village (a temporary winter ice town with bars, restaurants and a chapel), snow rafting, snow tubing, husky sledding, the Cloud Walk and indoor playgrounds — making it one of Japan's most family-rounded winter resorts where non-skiers and mixed-ability groups can fill every day.
Mina Mina Beach: the all-weather indoor wave pool
Mina Mina Beach is one of Tomamu's defining attractions and the single biggest reason families with mixed-age children love this resort. It's a vast indoor swimming complex with the largest indoor wave pool in Japan — actual surfable waves, white sand "beach" area, palm trees, slides for kids of all ages, and a separate warm-water lagoon for toddlers. The temperature inside is a permanent 30°C regardless of what's happening outside, which is a magical contrast to the snow falling on the windows.
Adults can sit on loungers reading while kids exhaust themselves in the pool — exactly what's needed mid-week when small legs have had enough skiing. Entry is included with most resort accommodation packages including stays at Alpha Ski Tomamu, so you're not paying extra to use it. Most families build a non-ski rest day around Mina Mina, often combined with a visit to one of the nearby restaurants. Kids will ask to come back every single day. Bring swimsuits and goggles; rentals are available but expensive.
The Ice Village (Aisu no Mura)
The Ice Village is a temporary town built entirely from ice and snow each December, melting back into the landscape each March. It includes an ice chapel where couples can hold ceremonies, an ice bar serving drinks in carved-ice glasses, an ice restaurant, ice slides for children, an ice ring (ice skating rink), and a series of ice domes housing various themed installations that change year to year. It opens nightly from late December through mid-March, lit by warm-coloured lights that make the ice glow.
The whole village is kept at around -10°C — yes, it's cold, even by Hokkaido standards — but the experience of walking through illuminated ice corridors with snow falling around you is genuinely magical, especially for children seeing it for the first time. Free shuttle buses run from the resort hotels including the stop nearest Alpha Ski Tomamu. Plan for 60-90 minutes in the village; longer if your kids want to do the slides repeatedly. Dress in your warmest layers, bring gloves, and pack a hot drink for the walk back.
Snow tubing and sledding hills
Tomamu maintains dedicated snow-play areas separate from the ski runs, where families can rent snow tubes (large inflated rings) and sleds for purely-for-fun runs down a gentle, fenced groomed slope. There's a covered magic-carpet conveyor to take you back up — no climbing required. Children as young as three can join in with a parent, and most kids will happily lap the run dozens of times in a single afternoon, making this one of the cheapest hours of fun in the entire resort.
The snow tubing area is a 5-minute walk from the main village and well-signposted in English. Tubes are hired in 30-minute or 60-minute blocks at modest cost, and warm rest areas with hot chocolate are right next to the slope. For non-skiing grandparents accompanying young grandchildren, this is often the activity of the trip — they can fully participate without ever needing skis on their feet, and the photos are wonderful.
Snow rafting and snowmobile experiences
Snow rafting is exactly what it sounds like — a large inflatable raft towed across snow fields by a snowmobile, with passengers hanging on for dear life. It's silly, exhilarating, and very popular with kids aged 6 and up. Sessions run on a published schedule across the day from a base near the cross-country trails. Snowmobile tours are also available for older teens and adults who want a faster-paced 30-90 minute guided ride through forest tracks.
Both activities require booking ahead during peak weeks — same-day availability often disappears by mid-morning. Cold-weather gear is provided (helmets, gloves, snow suits), so you don't need to bring specialist kit. For families with mid-teens who are starting to find skiing a bit repetitive, adding a snow rafting session in the middle of the week resets their enthusiasm and gives them something different to talk about back at school.
Husky sledding excursions
Several local operators run dog-sled experiences using teams of Siberian huskies trained for the snow. Sessions range from 20-minute introductory rides where you're towed by an experienced driver, through to longer guided experiences where older children and adults learn to drive the team themselves. The dogs are a joy in their own right — playful, vocal, and visibly built for this work — and most experiences include time to meet and pat the team before the run.
Dog sledding usually requires a short transfer from the resort village to the start point, which the operator arranges. Book at least a week in advance during ski season; the popular operators sell out their daily slots. This activity is particularly meaningful for animal-loving children and is often the standout family memory of the entire trip. Photos with the dogs at the end are a highlight that gets sent to everyone in the extended family group.
The Tower Pavilion playground and indoor activities
The Tower Pavilion at the base of Tomamu Mountain houses an indoor children's playground with climbing structures, ball pools, soft-play areas, art and craft sessions, and a small library of Japanese and English picture books. Entry is typically free for resort guests, supervised, and warm — perfect for very young children on storm days when even Mina Mina feels like too much. There's also an indoor archery range, virtual-reality games, and a small games arcade for older kids.
Other indoor options scattered around the resort include the Cloud Walk pavilion, gift shops, art installations, and quiet reading lounges. None of this is high-octane entertainment — Tomamu's appeal is the variety of low-key options that let mixed-age family groups split off and reunite easily through the day. The resort genuinely understands that not everyone in a family wants to do the same thing every minute, and the layout reflects that.
Family dining options
Tomamu's restaurant scene is unusually family-friendly by Japanese standards. Most restaurants on Hotalu Street accept walk-ins for families, have kids' menus, provide highchairs without fuss, and serve early enough for tired children. Forest Rinco serves a Hokkaido-themed buffet that's hugely popular with families because picky eaters can choose for themselves. Hotalu Street has yakiniku (grill-your-own beef), a ramen specialist, sushi, and an izakaya, all within a 3-minute walk of each other.
For families staying at Alpha Ski Tomamu with kitchen facilities, the convenience store at the resort base stocks excellent ready-meals, fruit, snacks and breakfast items at much lower prices than restaurant equivalents. Many families do a mix — restaurant dinners on three or four nights of the week, in-apartment meals on the others. Self-catering breakfast in the apartment also avoids the morning rush of family-with-kids restaurant logistics.
What to pack for kids in a Tomamu winter
Hokkaido winters are reliably cold but not extreme — typical mid-January days run -8 to -2°C, dropping to -15°C on cold mornings. Kids need proper insulated ski jackets and pants, two pairs of merino base layers (so one can dry while the other is worn), warm waterproof gloves with spare backup pairs, ski socks (not ordinary socks, which bunch and cause blisters), goggles, neck buff or balaclava, and warm helmet. Most rental shops at the resort hire kids' ski clothing on a daily basis if you don't want to buy and pack the lot.
Indoor essentials include swimsuits and goggles for Mina Mina, slippers for the apartment, comfortable warm clothes for evening dining, and any prescription medications. Bring a small daypack for each older child to carry their own water, snacks, sunscreen and small camera. Hand and foot warmers (single-use chemical sachets) are cheap at the resort convenience store and a small godsend for younger kids whose extremities cool fast on lift rides.
A sample family day at Tomamu
Day three of a typical family week: lazy breakfast in the apartment until 9, kids' ski lesson at the base from 9:30 to 11:30 while parents do a couple of runs together, family lunch at the base lodge ramen counter at noon, an hour of family ski together from 1pm on the green run, then everyone parks gear and walks five minutes to Mina Mina for two hours of pool time, hot bath back at the apartment, dinner at the Hotalu Street yakiniku, and finishing the day with a 30-minute walk through the Ice Village before bed.
Days like this — where everyone in the family does something they love, and nobody does anything they're not in the mood for — are the reason families return to Tomamu year after year. Alpha Ski Tomamu's central location makes the daily logistics easy, and our team can help you build the right week with the right balance of skiing and everything else.
