Money logistics are one of the least glamorous parts of planning a stay abroad, and also one of the easiest to get wrong in ways that cost you unnecessarily. Here’s what actually matters for a monthly stay in Tokyo.
Banking: you likely don’t need a Japanese bank account
Opening a bank account in Japan as a short-term visitor is difficult, and for a stay of a month or two it’s usually unnecessary. If you do need one, the ease varies a lot by institution. Japan Post Bank is the most accessible, generally requiring only about three months of residency versus roughly six months at most other banks. Online banks such as Rakuten Bank, Sony Bank, and PayPay Bank are a reasonable middle option. Regional banks come next, and the major "mega banks" — MUFG, Mizuho, and SMBC — tend to be hardest for foreign residents, with more Japanese-only paperwork. If you go this route, expect to need your residence card, proof of address, passport, a Japanese phone number, and sometimes a personal seal (hanko). For most monthly stays, an international card or a travel-friendly multi-currency account handles everything without any of this.
Card fees add up faster than the exchange rate
The bigger cost for most travelers isn’t the yen exchange rate itself, but foreign transaction fees and poor ATM withdrawal rates. Before you arrive, check whether your card charges a foreign transaction fee, and consider a travel-focused card or account designed for low or no fees abroad — the savings over a month of daily spending are meaningful. 7-Eleven ATMs and Japan Post Bank ATMs are the most reliable for international card withdrawals nationwide, including late at night.
What utilities actually cost in Tokyo
If you’re in a standard (non-bundled) apartment, monthly averages run roughly ¥6,500–7,000 for electricity, ¥4,000–5,000 for gas, ¥2,000–3,000 for water, and ¥4,000–6,000 for internet — a combined ¥15,000–30,000 per month. Electricity is commonly supplied by TEPCO, ENEOS Denki, or Looop Denki; gas by Tokyo Gas or ENEOS Gas; water through the metropolitan water service; and internet via fiber or wireless providers, usually billed monthly or bimonthly by card, bank transfer, or convenience-store payment. The real advantage of a monthly apartment is that most or all of this is already bundled into a single rate — always confirm exactly what’s included before booking, since a lower headline rate sometimes hides utility costs added on separately.
Budgeting for a realistic monthly cost
Beyond your apartment, plan for groceries, transport, and dining out. Grocery costs in Tokyo are broadly comparable to other major global cities, sometimes lower for produce bought at local markets rather than convenience stores. Transport is inexpensive per trip but adds up if you commute daily — an IC card with auto-recharge makes this easy to track.
Keep a simple record as you go
A month is long enough that untracked spending can drift more than you’d expect, especially with a new currency and unfamiliar price points. A basic running total — even a simple notes app — helps you notice early if dining out or taxis are eating more of your budget than planned.
Getting the apartment cost right from the start
Because early reservations on monthly apartments can save up to 60% compared to booking close to your move-in date, the single biggest financial decision is often how early you start the process — not which card you use once you’re here. If you’re planning a trip, reach out a few months ahead and we’ll help you lock in a fair rate before availability tightens.
