Question

Answer 1

A visa isn't like a passport where you can use it in every country. One country, one visa. Except of course Schengen visa. You may need to contact the Japanese Embassy in your country if you wish to visit the Land of the Rising Sun.**

Answer 2

each country has their own visa policies, you visa for Singapore is only good for Singapore,

you must apply for a visa to enter Japan
