Caution regarding "re-entry to Japan"

If you are a Japanese national or a registered foreign resident of Japan and you re-entered Japan on re-entry permit within three months of leaving the country, the period of validity of an international driver's license or foreign driver's license does not start anew from the date of re-entry.

In other words, when going overseas and returning to Japan the period of license validity starts anew only if you are away for three months or more. Note therefore, that if you stay away for less than three months you may not be allowed to legally drive in Japan on your return.
