VoIP is fully legal in Japan. The Ministry of Internal Affairs and Communications (MIC) regulates telecommunications, and VoIP services — including the popular 050 IP phone numbers — are widely used. Browser-based VoIP calling is unrestricted.
NTT, SoftBank, and KDDI are the main carriers. International calls typically cost ¥30-100 per minute. Japan has relatively high international calling rates compared to other developed countries. 050 numbers (VoIP-based phone numbers) are popular but require separate registration.
Japan has a unique telecom landscape where LINE is so dominant that many people rarely need traditional international calling. However, LINE only works for LINE-to-LINE calls — you cannot call a regular phone number. For calling family abroad who don't use LINE, or for business calls to regular phone numbers, a service like PhoneTheWorld is essential.
Many Japanese users try to get Google Voice working through unofficial methods. Here's what people attempt — and why PhoneTheWorld is simpler.
PhoneTheWorld requires none of these workarounds. Just sign up with your email, add credits, and start calling — it works natively in Japan.
