• 1

  Japan publishes mortgage figures in Japanese Yen, revised periodically — enter the rate currently in force for your case in Japan rather than an older stored figure so the result matches the official calculation.

• 2

  Treat the computed Japanese Yen amount as the base figure for Japan: any additional local fees, deductions, or rounding rules that apply to your situation must be added separately, so the number you rely on stays honest and complete.

• 3

  Keep the mortgage amount and rate for Japan on one period and one basis — monthly Japanese Yen figures with an annual rate, or gross with net, give a number that is arithmetically right but misleading in practice.

• Quoted rates are rarely effective rates: Japan providers may advertise a nominal figure while fees raise the true cost in Japanese Yen. Compare on one basis — effective rate, same period — before trusting the Mortgage output.

• A percentage entered as a whole number where a decimal is expected (15 versus 0.15) is off by ×100 — the most common single error in rate fields. Check which form the Japan Mortgage field expects before you type.
