Quick Answer Best banks for new foreign residents in Japan: Japan Post Bank (ゆうちょ) accepts foreigners from day one with just a residence card and passport. Rakuten Bank is 100% online with English support. Sony Bank offers foreign currency accounts and fee-free Visa debit. Avoid the major megabanks (MUFG, SMBC, Mizuho) until you have 6+ months of residence — they frequently reject new arrivals. You need a Japanese bank account to get paid, pay rent, and handle almost every part of daily life here — and you need one fast. The problem is that banks in Japan are notoriously picky: wrong visa type, wrong documents, or not enough residency history, and you walk out empty-handed. This guide tells you exactly which banks accept foreigners with minimal fuss, what documents to bring, and how to have an account open within a week of landing. ...

Quick Answer Foreigners can rent apartments in Japan privately, but you need a guarantor company (保証会社), valid visa, and upfront costs of 4–6x monthly rent. Use foreigner-friendly agencies like Sakura House, Able, or Suumo’s foreigner support services to simplify the process. Apartment hunting in Japan is stressful for everyone — but as a foreigner, you’re starting with a stack of extra obstacles. Some landlords will say no simply because of your nationality. The paperwork is in Japanese. The upfront costs are genuinely significant. And the “guarantor” requirement traditionally assumed you knew a Japanese person willing to vouch for you financially. ...

Quick Answer Japan’s convenience stores (コンビニ, konbini) are open 24/7 and do far more than sell food. At any 7-Eleven, Lawson, or FamilyMart you can: pay electricity/gas/water bills in cash at the register, withdraw money from an ATM that accepts foreign Visa and Mastercard cards (7-Eleven is most reliable), print or scan documents (¥10–30/page), send a package nationwide, receive online deliveries, buy concert and event tickets, and fax documents. The food — onigiri, hot fried chicken, bento boxes — is genuinely good quality and cheap (¥130–400/item). ...

Quick Answer Japan is one of the most cash-dependent developed countries in the world, though this is changing quickly. Many small restaurants, local shops, temples, and some clinics are cash-only. Always carry ¥5,000–10,000 in cash. Best ATM for foreign cards: 7-Bank (inside 7-Eleven), available 24/7. For residents, a Japan Post Bank or Rakuten Bank account with a Visa debit eliminates most daily cash friction. PayPay (QR code payment app) is increasingly accepted where cards are not. ...

Quick Answer Japan’s rainy season (梅雨, tsuyu) runs approximately June 8 to July 21 in Tokyo (varies by region and year), bringing high humidity (85–95%), frequent rain, and major mold risk. Essentials: a good umbrella (not a travel umbrella — a real one), a dehumidifier or silica gel packs, anti-mold spray for bathroom grout and window frames, and preparation for clothes that won’t dry. Mentally: the grey skies compound expat seasonal mood dips — build outdoor activities for the breaks in rain. ...

Quick Answer Key money (礼金, reikin) is a non-refundable payment of 1–2 months’ rent made directly to the landlord when signing a Japanese lease. It is not a deposit — you get nothing back. Combined with security deposit (敷金), agency fee (仲介手数料), and guarantor insurance, move-in costs in Japan typically reach 4–6 months’ rent before you spend a yen on furniture. Key money has no legal requirement — many apartments, especially newer ones and UR housing, no longer charge it. ...

Quick Answer LINE is Japan’s dominant messaging app with over 96 million active users — effectively the national communication infrastructure. Your employer will use it for team updates, your doctor’s clinic may have a LINE account for appointments, your kids’ school communicates via LINE, and Japanese friends will expect to exchange LINE IDs, not phone numbers. Download it before you arrive, register with your Japanese phone number, and treat it as an essential utility, not a social media app. ...

Quick Answer Culture shock in Japan follows 4 stages: Honeymoon (everything is exciting), Frustration (everything is exhausting), Adjustment (finding coping strategies), and Adaptation (functioning effectively in both cultures). Most foreigners hit frustration at 3–6 months. The key insight: frustration is a sign of engagement — you’re experiencing Japan deeply enough to be affected by it, not just observing from a distance. “I came to Japan because I loved everything about it. Now I find myself irritated by things I used to love. What happened?” ...

Quick Answer Expat burnout in Japan often builds slowly and invisibly: you’re managing a foreign language, decoding cultural rules, working long hours, and doing it without your normal support system. Warning signs include emotional numbness about Japan, dreading social interaction, physical exhaustion that sleep doesn’t fix, and growing resentment toward Japanese people or culture. It’s treatable — but first you have to name it. It doesn’t announce itself. One day you realise you’ve stopped noticing things you used to find interesting. The food that excited you is just fuel. The country that felt like an adventure feels like a sentence. You’re exhausted in a way that sleep doesn’t fix, and you’re not sure why. ...

Quick Answer Getting medical care in Japan as a foreigner: start at a clinic (クリニック), not a hospital — clinics are cheaper, faster, and handle 90% of needs. Bring your health insurance card (保険証) and residence card. For English-speaking doctors, use the AMDA International Medical Information Center (03-5285-8088) or search Zocdoc Japan / Japan Healthcare Info. Out-of-pocket with National Health Insurance is typically ¥1,000–3,000 for a GP visit. “I had a fever of 39°C and no idea where to go or how to explain what was wrong.” That’s one of the most stressful experiences foreigners in Japan report — needing medical care urgently and not knowing the system. ...
