First Week in Japan: Practical Setup Guide for Daily Life

Arriving in Japan is an exciting milestone, but the first week is much more than a sightseeing opportunity or a simple move-in process. It is a critical 168-hour setup window where your daily life systems are established. Establishing your connectivity, payment pathways, transit habits, and basic apartment organization early saves you time and avoids friction.

This guide outlines the core steps to make your transition into Japan smooth, practical, and highly efficient.

Without reliable mobile data, navigating Japan is extremely difficult. You need connectivity for maps, translation services, messaging apps, and local emergency information.

• eSIM: Usually the most convenient option if your device supports it, allowing instant activation upon landing.
• Physical SIM: Ideal for older devices, available for pick-up at major airports.
• Pocket Wi-Fi: Ideal if you have multiple devices (laptop, tablet, phone) that need data simultaneously.

Decide and arrange this before you arrive to avoid overpaying at airport service counters or spending days offline.

While credit card acceptance is growing, Japan remains a society where cash is essential for smaller shops, local eateries, and laundromats.

• Cash Reserves: Keep a small amount of physical yen for immediate needs. Standard cash withdrawals are most conveniently made at convenience store ATMs (such as 7-Bank or Lawson Bank), which support international debit cards.
• Transit IC Cards: Secure a Suica or Pasmo card. If physical cards are unavailable due to global chip shortages, add a digital transit card directly to your phone's Apple Wallet or Google Wallet. This works for trains, buses, and instant payments at convenience stores and vending machines.
• Foreign Card Friction: Be prepared for occasional card rejection at local online portals or smaller retail terminals. Always carry a secondary payment method.

Japan’s transit system is world-class but complex. Navigation apps (like Google Maps or local routing tools) are indispensable for platform numbers, transfer times, and station exit guidance.

• Station Exits: Train stations in cities like Tokyo can have dozens of exits. Check which exit matches your final destination before leaving the platform to avoid long detours.
• Luggage and Rush Hours: Avoid traveling with large suitcases on trains during morning (7:30–9:00 AM) and evening rush hours. If moving heavy luggage, consider using domestic luggage forwarding services (takuhaibin) directly from the airport to your lodging.
• Walking Reality: Be prepared for significant walking distances inside station transfers. Comfortable, supportive walking shoes are essential.

Japanese convenience stores (konbini) like 7-Eleven, Lawson, and FamilyMart are high-quality lifestyle hubs. Reaching for konbini meals is a practical option for busy setup days, but smart choices keep you energized.

• Nutritional Balance: Look for ready-to-eat protein sources like steamed chicken breast (salad chicken), grilled fish, and boiled eggs. Pair them with fiber-rich options like seaweed salad or edamame.
• Hydration: Buy unsweetened green tea, barley tea (mugicha), or water in bulk rather than sugary soft drinks to handle warm temperatures.
• Avoiding Restaurant Fatigue: Dining out for every single meal can be expensive and time-consuming. Using convenience stores for quick, balanced breakfasts or light lunches keeps your schedule flexible.

Japan’s climate can shift rapidly, with high humidity and heat in summer, sudden rains, and cold winters.

• Layering System: Pack and wear lightweight, breathable layers that can be easily stowed in a backpack. Merino wool or synthetic tech fabrics work well.
• Rain Readiness: A compact, lightweight folding umbrella is a non-negotiable commuter tool. Avoid cheap plastic umbrellas from convenience stores if you want something that lasts and fits easily in your bag.
• Footwear Care: Bring water-repellent or quick-drying shoes, and keep shoe inserts handy to manage dampness from walking outside.

Moving into a new Japanese apartment requires immediate adaptation to local residential standards.

• Trash Sorting: Waste disposal rules are highly detailed and vary by municipality. Secure separate bins or bags for combustible waste, non-combustible waste, plastics, and recyclable bottles/cans.
• Entryway (Genkan) Manners: Never wear outdoor shoes past the raised step of the genkan. Keep a dedicated shoe tray or vertical rack to organize footwear in narrow entrance spaces.
• Laundry & Drying: Most apartments do not have clothes dryers. Set up a compact folding rack in a well-ventilated indoor spot, and use a fan or circulator to prevent dampness and odors.

Managing your paperwork and personal safety basics during the first week ensures a worry-free stay.

• Physical Document Management: Keep your passport, residence card (zairyu card), and health insurance card securely stored in a flat, water-resistant organizer. In Japan, foreign residents are legally required to carry their residence card at all times.
• Medication & Health Planning: Ensure you bring an adequate supply of personal prescription medicines, along with English copies of your prescriptions or doctor’s notes. Standard over-the-counter painkillers or cold medicines can be found at local drugstores, but active ingredients may differ from those in your home country.
• Emergency Contacts: Store local emergency numbers in your phone: 119 for fire and ambulance, and 110 for police. Keep a physical note of your lodging address in both English and Japanese.
