Ogna

The closest beds are in the Hanasaku area of Katashina, right below the resort. Okuhotaka Onsen Hotel Hoshitei is about as close as it gets and runs a shuttle to the slopes, while small family-run pensions such as Pension Kobold are a couple of minutes' drive away. Expect simple rooms, big set dinners and hosts who are used to skiers wanting breakfast early. The Hanasaku no Yu day onsen is close by for a post-ski soak.

For more flexibility, base in Numata or Minakami. Numata has practical business hotels near the expressway, which makes it easy to switch between Ogna, Hodaigi, Kawaba, Tambara Ski Park and Oze Iwakura depending on the forecast. Minakami adds riverside onsen ryokan and puts Mt. T within reach. It is not glamorous, but it is a good base if you are playing the weather.

For a treat, book a ryokan with a rotenburo (outdoor bath) for a night. Soaking under cold air after a morning in the steeps is the ideal end to the day, and the dinners lean on mountain vegetables, river fish and local mushrooms. Nightlife in the valley is close to zero, so plan on early nights. Our ryokan explainer covers what to expect.

The snow is the reason to come. Ogna's base sits at around 1,200 metres, which is high for this part of Honshu, and the north Gunma location catches the tail of Sea of Japan storms after they cross the ranges. Totals are modest next to Niigata, but the snow that does fall stays cold and light, and the surface holds well between systems. On a clear day after a cold night, the groomers set up firm and fast.

The steeps are short but real. The Expert Course off the No. 7 pair chair hits 32 degrees, and the neighbouring Training and Wedeln courses sit around 30. Wedeln is managed as an ungroomed zone and Training is the designated powder run, so those are the first places to go after an overnight top-up. The Slalom Course runs part groomed, part natural, which makes it a handy spot to switch between carving and soft snow on the same lap. None of these are long, so they ski best as rapid repeats off the No. 7.

Intermediates get the best value. Hotaka Skyway is the signature run, a 2,250 metre cruise that links into the longer top-to-bottom route and holds a consistent, friendly pitch the whole way. The No. 4 and No. 6 slopes add more blue terrain with enough grade to practise speed control. Beginners have the long Romance Course, a gentle 1,500 metre run served by its own lift, plus a learner slope by the base and a snow escalator for the very first turns.

Trees are a sideshow. You will find a few low-angle birch lines along the edges of the runs, but there is no gate system and the boundary ropes are firmly enforced. Patrol can take your ticket for ducking them, and the terrain outside the area hides gullies and long, flat exits. If you want proper freeride, head to Mt. T on a stable cycle and use Ogna for the days in between.

On a storm morning, head straight for the upper chairs while visibility holds and work the ungroomed runs before they are tracked. As the day wears on and the light flattens, drop to the longer intermediate runs, where the grooming keeps things readable. Weekdays are quiet enough that the soft snow lasts. Saturdays bring Kanto families and school groups, but most of them stay low, so the upper chairs stay manageable.

By car, take the Kan-Etsu Expressway to Numata IC, then follow the road up the Katashina valley. Allow around two to three hours from central Tokyo in normal conditions, more on Saturday mornings and holiday weekends, when the expressway can crawl. The last climb is steep and twisting, so proper winter tyres are essential and carrying chains is sensible when heavy snow is forecast. Parking is free. Our guide to winter car hire and driving in Japan covers the basics.

Without a car, the Katashina Snow Express bus runs daily from Shinjuku through the season and is the easiest option. By train, take the Joetsu Shinkansen to Jomo-Kogen, or a local line to Numata, then a bus up the valley. Connections are thin, especially midweek and in the afternoon, so plan around the timetable. Our Japan ski transport guide explains how buses, trains and transfers fit together.

Strong intermediates and carvers will love it. Long, consistent runs, good grooming and cold snow make Ogna a great place to work on technique, and the short steeps give you something to aim at. Families also do well: the beginner terrain is long and separated from the faster runs, and the base is compact enough that nobody gets lost.

Advanced riders will enjoy a powder morning here, but they will have the best runs dialled by lunch. Anyone whose trip is built around trees, gates or backcountry should treat Ogna as a recovery day rather than the main event. Japan first-timers deciding between regions can start with the resort finder.

The base centre does the classics: katsu curry, ramen, karaage and rice bowls, served quickly and priced fairly. Coffee is basic but hot. It will not win any awards, but lunch will not cost you a run either.

Down in the valley, Katashina leans hearty and rural. Look for hand-cut soba, set meals with grilled trout and tempura made with local mushrooms and mountain vegetables. Choice is limited, especially on weekday evenings, so many visitors eat dinner at their pension or ryokan. Après means an onsen, a beer and an early night. If you want bars, you will need to drive to Numata or save it for Tokyo.

• Lift hours: 8:30 to 16:00 on weekdays and 8:00 to 16:00 on weekends and holidays. There is no night skiing, so start early.
• Tickets: A weekday discount applies outside the New Year holiday. Web tickets are collected from the machine in the centre house.
• Off-piste: No gate network. Ropes are enforced and patrol may take your pass for ducking them.
• Weather: The altitude keeps snow cold, but the upper chairs are exposed. Bring a face mask for windy days.
• Language and payment: Limited English, but the layout is simple. Carry cash for small restaurants and pensions in the valley.

Ogna is one of a cluster of resorts in north Gunma. Oze Iwakura has more vertical and bigger groomers, Hodaigi offers long cruising runs and Marunuma Kogen adds a high base and a longer season. Mt. T is the pick when you want alpine freeride on a stable, cold cycle. For more ideas, see our list of ski resorts near Tokyo.
