Japan's international country code is +81. It was assigned by the International Telecommunication Union under recommendation E.164 and is the dialing prefix at the start of every Japan phone number written in international format.
You'll often see +81 referred to in search as the "81 area code". Strictly speaking, +81 is a country code — area codes are sub-national, used inside Japan. The practical meaning is the same: any number starting with +81 or 0081 is a Japan number.
TwinPhone routes calls to every +81 number directly from your browser — no app, no SIM card, no calling card. Type +81 followed by the local number, press call, and you're connected.
Dialing codes immediately above and below +81 in the ITU plan — handy if you mistyped a digit or are dialing across a region.
