Note
Every figure on this page is an estimate based on the values you entered and on defaults from Japanese national law, Tokyo's rules and common market practice, each as of the date shown next to it. This is not financial, legal or tax advice. The real amounts come from the tax notices, the judicial scrivener's (司法書士) bill and your lender's offer when you buy; check them before you sign. The site does not store the numbers you enter; they stay in the page address.
Monthly rate is the annual rate divided by 12; amounts are in whole yen. Registration and acquisition taxes are worked out on the assessed values you enter, not the price, with the base cut down to the ¥1,000 and the tax to the ¥100.
The link carries only the numbers you entered. The site keeps no copy of them.

- Annuity / equal installments
A repayment method in which every monthly payment is the same amount, principal and interest together, as long as the rate stays the same.
- Declining balance
A repayment method: the same principal every month plus interest on what is still owed, so the first payment is the highest and each later one smaller.
