Your salary matters far less than what is left after rent, food, and transport. These three markets have very different cost profiles, and the cheapest city is not always the one that pays least.
Housing and rent
In Korea, schools commonly provide a furnished studio or a monthly housing allowance, which removes the biggest expense from your budget. In Japan, some employers help with the first apartment, but most teachers pay their own rent. Taiwan usually expects you to find your own place, but rent in cities outside Taipei is very reasonable.
If you rent privately, deposits vary a lot by country. In Taiwan, expect about two months’ rent. In Japan, move-in costs such as key money, agency fees and a deposit often add up to three to five months’ rent. In Korea, monthly rentals usually need a much larger deposit — often KRW 3–10 million (about $2,000–$7,000) — which is returned when you move out.
Food and transport
Local food is affordable in all three markets. Eating out at casual restaurants costs roughly $4 to $10 per meal, while Western groceries and imported goods are the main budget risk.
Public transport is excellent and cheap across the region. Monthly transport in Seoul, Tokyo and Taipei usually costs $30 to $100, and Japanese employers often reimburse your commute.
- South Korea — high rent if not covered, very cheap food and transport
- Japan — premium city rent, efficient but pricier transport
- Taiwan — lowest overall cost of living

Rough single-person estimates for a major city. Smaller cities are usually cheaper.
After housing, most teachers spend $400 to $900 a month on food, transport, phone, and going out. Keep that figure in mind when comparing offers — it can be the difference between saving nothing and saving well.
What you can realistically save
With housing covered, teachers in Korea commonly save $800 to $1,200 a month. In Taiwan, lower costs often allow similar savings even without free housing, while teachers in Tokyo or Osaka tend to save less unless they share an apartment or live outside the city center.
Track your first month of spending carefully against your salary, then adjust before you get comfortable.
