How much percent tax does Japan have?

Question:

Like do they have gst, pst all those types of taxes?
If I buy something for 100 yen, how much tax will be added on to the total price?

Answer:

You have to pay 5% with something like GST and PST combined in Japan.

You have to pay 105 yen.

You said "all taxes". But it's long to explain about other taxes like income tax or cooperation tax.
