Take Keikyu Line (to Shinagawa) + JR to Tokyo Station or the Airport Limousine depending on luggage — approx 40–60 minutes to Tokyo Station, then make your shinkansen connection.
Board the Hokuriku/Asama shinkansen from Tokyo to Nagano (about 1h30m). Reserve seats if possible; trains are frequent but winter weekends can be busy.
Transfer to the Alpico/Nagaden bus from Nagano Station to Hakuba (approx 1h–1h20). Snow conditions are normal for February but allow some margin for winter traffic.
Check in at a Hakuba ryokan/hotel or guesthouse and warm up in an on-site onsen or public bath — many onsen operate afternoon→late-evening (confirm hotel hours).
Head to Hakuba’s Echoland area for a cozy izakaya meal or try local soba for warming mountain flavors; Echoland restaurants are lively in the evening and perfect after travel.
Take the resort shuttle or local bus to Happo-One (approx 10–30 minutes depending on lodging); lifts typically start around 8:30–9:00 in winter — check lift opening times before you go.
Enjoy Hakuba Happo-One’s long runs and varied terrain — it’s a premier resort for powder and views of the Northern Alps. Prioritize popular lifts early; lift hours commonly end around 4:00–4:30pm.
Return to your accommodation or a public onsen for a soothing soak to relieve tired muscles; many onsen near Happo are open through the evening (confirm local hours).
Organize transport/tickets for tomorrow (if doing Snow Monkey day trip) and rest for an early start; many shops close early in mountain towns so prepare ahead.
Have an early breakfast and catch the bus toward Nagano Station to connect to the Nagano Dentetsu line for Yudanaka — an early start ensures time at the park and a relaxed return.
Board the Nagano Dentetsu (local/private line) from Nagano to Yudanaka (approx 40–50 minutes); trains are scenic in winter — buy tickets at Nagano Station.
From Yudanaka/nearby bus stop, take the local bus or taxi to the park trailhead and walk (~30–40 minutes) through forest to see wild Japanese macaques bathing in hot springs — park hours are generally around 9:00–16:00 in winter, so check current times.
Retrace by train and bus to Nagano then the Hakuba bus — total travel back is around 2–2.5 hours depending on connections, so expect to arrive in Hakuba late afternoon.
Head to Shibuya for the famous crossing, Hachiko statue and nearby Harajuku/Omotesando for a stroll and lunch; this gives a modern Tokyo contrast to your mountain days.
If you prefer calm, visit Meiji Shrine (open in winter daylight hours) or wander Ginza for shopping and tea; plan to finish early to collect luggage and head to Haneda.
Enjoy a last Tokyo meal — standing sushi bar in Ginza, ramen, or a cosy izakaya near Tokyo Station; keep enough time to travel to the airport comfortably.
Take the Keikyu Express or Airport Limousine (allow ~1 hour from central Tokyo to Haneda with traffic margins). Aim to arrive ~3 hours before the midnight (00:05) international flight.
