Is renewal of the period of stay of "Short-Term Stay" permitted?

"Short-Term Stay" generally means staying within 90 days.
In addition, most of the purposes of visiting Japan for "Short-Term Stays" are tourism and business, so it is not expected that the period of stay will be renewed.
However, if updates are not allowed at all, that is not the case.
If there are "true humanitarian unavoidable circumstances or special circumstances equivalent to this", the period of stay may be renewed.
For example, if you were hospitalized due to illness or injury while staying in Japan and could not leave the country during your period of stay.
However, this is an exceptional measure, so it is necessary to apply for it within the deadline and get permission.
