I bought this solar-powered Casio calculator at the weird ‘n wonderful Olympic store in Koenji, Tokyo, 31 years ago. Olympic is just a few blocks from one of the apartments I lived in during my Japan years.

Olympic is one of those places where you can get dry goods, clothes, luggage, sports equipment, bicycles, electronics, etc., spread over four or five jumbled floors.

We dropped into Olympic on our last Japan trip a few years ago.
