Just northwest of Sapporo, the Sapporo Teine ski area has 15 courses served by 13 lifts that access a maximum vertical descent of 450m. It has north-facing slopes known for deep power stashes on steep slopes. Sapporo Teine consists of two small ski areas, Olympia and Highland. The Olympia ski area is typically for beginners, while the Highland ski area is better for advanced beginners. The Sapporo Tiene Highland zone is known for the steepest inbounds terrain in all of Japan. There is a gondola between the two mountains, neither of which has big vertical. There is off-piste and side-country terrain that is technically not allowed, but there is no enforcement. The most popular side-country is under the old cable car located on skiers-left of the resort. Further to the left, some out-of-bounds hiking leads to three off-piste bowls. Look for the N1-N5 marked off-piste zones. There is a terrain park located at Olympia.
To reach the snowboarding at Sapporo Teine by plane, fly into Sapporo New Chitose airport (CTS) on the southwest side of Hokkaido just southeast of Sapporo. There are numerous direct inter country flights from Tokyo. From the airport, there are numerous shuttle bus options to the various Hokkaido ski resorts. While at the airport, make sure to use the ATM since ATM machines can be quite hard to find at the resorts (especially ones accepting international cards) and credit cards are rarely accepted. From Sapporo, there is a train to the town of Teine. Once in Teine, there is a bus up to the ski area. Keep in mind that it is possible to stay right in Sapporo and some hotels offer a free shuttle bus up to the ski area.
In addition to flying into Sapporo from Tokyo, there is also a train tunnel connecting Hokkaido Island with the main Honshu Island. The train route from Tokyo northbound passes through Aomori, and the total trip takes between 9 to 11 hours.
Note - keep in mind that the ski areas on Hokkaido are not known to be particularly steep, but they are well known for big snow fall. They are also known for their ones, which are hot thermal spring-fed indoor or outdoor pools (be aware that they are usually naked pools). When snowboarding and freeriding internationally, it is important to get a travel insurance policy that covers emergency rescue, medical expense and evacuation. There are many destinations that will not initiate rescue or medical treatment without prior payment or proof of insurance. In many cases, the rescue fees, medical fees or evacuation to a reputable hospital can total tens of thousands of dollars. Plans such as GEOS SAR100 or IMG Patriot Travel Medical Insurance are well worth the per-trip cost of $130 to $200 USD.
Overall, Sapporo Teine is the 8th most popular snowboard & freeride destination of all 22 snowboarding resorts in Japan.
