Leave the suitcase: packing for three days out of a month-long base
Most trips to Japan are spent moving luggage. You check out, you wheel a suitcase to a station, you find the coin lockers are full, you check in somewhere else. A month in one place turns that on its head. Your things stay put. When you want to go somewhere — a ridge, a castle town, an onsen two hours out — you take a day pack and leave the rest in the room.
Here is how to actually do that.
What stays in the room
Everything you don’t need for two or three nights:
- The suitcase itself, most clothes, anything valuable you’re not carrying
- Chargers and adapters you have spares of
- The heavy layers you’ll only want back in the city
A furnished flat has a wardrobe and a lock. Use them. There’s no need to carry your whole trip up a mountain.
What goes in the pack
For an overnight or two on a trail, in the warmer half of the year:
- One change of clothes, plus a warm layer and a rain shell — the weather turns fast above 1,000 m even in summer
- Head torch, water (1.5–2 L, refill where you can), snacks, a small first-aid kit
- Cash — mountain huts and rural buses often don’t take cards
- Your phone, a paper map or an offline one, a power bank
- If you’re camping: sleeping bag, mat, tent — see below
That’s a 30–40 L pack, not a 70 L one. If you’re only doing day hikes and coming back each night, half of that.
Laundry between trips
You’ll get back with a bag of wet, muddy clothes and want to go out again in two days. A washer-dryer in the flat is the quiet luxury here — start a load when you walk in, and everything’s dry by the time you’ve had a bath and slept. Plan your trips a day apart and you never run out of clean layers.
The gear problem, solved by staying still
The catch with hiking from a short trip is the equipment. You either fly it in — a tent and a pack eaten straight out of your baggage allowance — or you rent, and the convenient way to rent (order online, have it delivered) needs a Japanese address you don’t have.
Staying a month fixes both. Your address is the flat. We keep a pack, boots and a tent that live in your room for the length of your stay, so you fly in with a normal suitcase and still walk out for three days on a ridge.
