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 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 Japan’s bureaucracy is process-heavy, paper-based, and office-specific — meaning the wrong office can’t help you even if it wanted to. The key: bring your residence card and passport everywhere, bring originals AND photocopies, go to the ward office (区役所) for most daily life registrations, and go in the morning (opens at 8:30–9:00, shorter queues). Google Translate camera mode is your most practical tool. “I went to three different offices and nobody could help me.” Sound familiar? Japan’s administrative system works — it’s actually remarkably efficient by international standards — but only if you’re inside the logic of it. For foreigners, the first few encounters feel like a bureaucratic maze designed to reject you. ...

Quick Answer The language barrier in Japan is manageable for tourism but genuinely stressful for long-term residents. High-impact moments: medical visits (symptoms in Japanese), bureaucratic forms, landlord communications, and workplace meetings. Most useful tools: Google Translate camera mode (instant sign/document translation), DeepL (superior for nuanced text), and a basic Japanese phrasebook for emergencies. Long-term, even N4–N3 level Japanese dramatically reduces daily friction. “Everyone was nice, but I had no idea what was happening for 30 minutes.” That’s the experience of a Japanese medical visit for many foreigners. Or the bank appointment. Or the phone call from city hall. ...
