What to explore
Start with Snow monkeys in winter: the 30-minute walk, the easiest wild day from Tokyo in winter: about 80 minutes by Shinkansen to Nagano, then a bus and a 2 km trail of about 30 minutes. The park says monkeys may not appear. Online tickets began on 6 August 2026; the on-site adult fee is $6 (¥1,000) from 1 December 2026, up from $5 (¥800).
Dollar figures use about ¥155 to US$1 and are rounded; you pay in yen, so check the rate. Yarigatake huts are cash only, so carry yen.
Safety FY2025 set a record: 216 incidents, 238 people hurt and 13 deaths (preliminary). Do not approach a bear. The Environment Ministry says to leave quietly if a bear is far, and to face it and back away slowly if it is near. Bear spray cannot go on an aircraft, so buy or rent it after landing. Brown bears hibernate from about December to March. Hokkaido bans feeding brown bears.

Can I…?
- Can I hike Kumano Kodo or the Alps without booking huts? Depends on the route. Alps huts require reservations, and the Kumano tourism bureau advises booking Kumano Kodo lodging about six months ahead for spring and autumn.
- Can I fish in Japan without a licence? Depends on the water. No national sea-fishing licence is listed, but visitors may fish small-scale only, rivers run by fishery cooperatives need a day permit and a cast net works from shore only.
- Can I dive in Japan without certification? Yes, on a guided introductory dive, which needs no card; fun dives need a certificate. An intro dive was listed at $180 to $205 (¥28,000 to ¥32,000).
What do the volcano levels mean?
Safety Level 2 means no approach to the crater area, and Level 3 means no entry to the mountain. Levels change within weeks: a news report (secondary) says Aso went from Level 1 to Level 3 between 21 June and 14 August 2026. Read the Japan Meteorological Agency map on the day you go.
Do you have to tell anyone before hiking?
In Nagano, yes on designated trails: a climbing notification (tozan todoke). Toyama requires a plan for the Tsurugi area from 1 December to 15 May, filed 20 days ahead. Gifu covers the Northern Alps, Yakedake, Ontake, Hakusan and Norikura, with a fine of up to $325 (¥50,000) reportedly cited.
Whale and diving seasons differ by source, so confirm with the operator. For Fuji, follow the official page: a reservation was optional until the Yoshida daily cap was reached, though some outlets call it mandatory.
Quick answers
Are wildlife sightings guaranteed in Japan?
No. The Jigokudani park says monkeys may not appear, and drift ice, cranes and whales depend on weather and timing. Ask the operator about your dates.
Can I climb Mt Fuji in winter?
Not as a normal climb. The 2026 Yoshida season ran 1 July to 10 September, and one guide reports that climbing above the 5th stations out of season is prohibited by law. From December to March, going above about the 8th station on the Yoshida trail requires a climbing plan.
Are bears a real risk when hiking in Japan?
Yes, on Honshu and Hokkaido. The Ministry of the Environment recorded 238 people hurt and 13 deaths in FY2025, a record (preliminary). Kyushu and Okinawa are reported bear-free. Make noise with a bell or your voice, check recent sightings and do not hike alone.
