A Japan leisure trip fails more often from wrong layers and tight transfers than from picking the “wrong” mountain.

Shared packing core

• Passport, cards, small cash, offline maps / JPFun shortlist screenshots.
• Rain shell, quick-dry mid layer, comfortable walk shoes.
• Medicine, power bank, universal plug.

Activity add-ons

• Ski: goggle spare, warm gloves, insurance details.
• Scuba: cert card photos, logbook, reef-safe sunscreen, seasickness plan.
• Surf: wax/comb if needed, rash guard, coin for showers.
• Camp: headlamp, trash bags, wind stakes, warm night layer.

Transit habits

• Build 30–60 minutes of slack on winter roads and island boats.
• One primary base per weekend — do not “collect” regions.
• Soft days (ramen / onsen / golf) live on peer maps: okramen.net, okonsen.net, okcaddie.net.
