Yes. A meal at a restaurant rarely costs under 800 yen, whereas a grocery-store meal cooked at home can easily be kept under 300 yen.

Avoid major carriers (Docomo, Au, Softbank). Use an MVNO (Mobile Virtual Network Operator) like LINEMO, IIJmio, or Mineo, which offer data plans starting around 1,000 yen.

How do I save on medical costs?

Ensure you enroll in the National Health Insurance (Kokumin Kenko Hoken). It covers 70% of your medical costs, leaving you responsible for only 30%.

Living on a Budget in Japan as an Expat

Live cheaply by shopping at local supermarkets after 7:00 PM for discounts, using the extensive network of local train lines instead of express ones, and choosing share houses over private apartments. Aim for a monthly grocery budget of 30,000 yen and prioritize cooking at home to keep living costs sustainable.

Master the 'Supermarket Discount' Timing. Japanese supermarkets apply stickers to pre-made meals (bentos, sushi, tempura) starting around 7:00 PM. Discounts start at 20% and reach 50% as closing time approaches. Go shortly before closing to secure your next day's lunch.
Choose Regional Trains Over Limited Express. When traveling between cities, always select 'Local' (futsū) or 'Rapid' (kaisoku) trains. You avoid the 'limited express' surcharge (tokkyū-ryōkin), which can double the cost of a ticket.
Use Share Houses (Share-House). Instead of signing a traditional Japanese lease, which requires high initial fees (reikin/shikikin), look for share houses. They come pre-furnished, include utilities in the rent, and require minimal to no deposit.
Leverage Point Cards and Cashless Apps. Sign up for point cards like T-Point or d-Point at drugstores and convenience stores. Use apps like PayPay for 0.5% to 1.5% cashback on daily purchases, which adds up over a month.
