• 1

  Japan publishes rent affordability 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

  Currency is part of the math: this Japan rent affordability computes in Japanese Yen, so convert a foreign source figure first — applying a local rate to a foreign amount silently inflates or deflates the result.

• 3

  A rent affordability result for Japan is only as current as the rate you typed in: when the figure matters, re-run it with a freshly confirmed Japanese Yen rate instead of one saved last month.

• Property charges in Japan are often banded: the percentage changes across Japanese Yen price slices, so one flat multiplication can misquote the total. Split the amount across the applicable bands before adding the parts back up.

• 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 Rent Affordability field expects before you type.
