[Accessible Japan]

Hey!

Of course it is OK to ask here!

Not living with IBS, but know the need of finding a toilet!  You may want to try out some of these toilet apps!  They can help you find the nearest toilet.  It certainly helps to just know where they are in a pinch.  The @トイレ app even has a big “Emergency!” button (it is actually made by a company that sells diarrhea medication) 🙂

• 緊急！トイレ情報共有マップくん！ (iOS, Android)
• ＠トイレ (by Lion, iOS, Android)
• Check a Toilet (iOS, Android)

These should at least help you when going out.  Even if in Japanese, you can still get the idea.

You mention working here?  After you move in and get on Japanese health insurance, you should go to a doctor to see about prescribed medicine.

Hope this helps!
