WorldESIM's plans for Japan are primarily data-focused and do not come with a local +81 phone number. Obtaining a traditional voice SIM as a tourist in Japan can be quite challenging due to local regulations. However, this doesn't hinder your ability to make reservations. Many establishments in Tokyo and Osaka now offer online booking systems (e.g., TableCheck, Google Reservations). For direct calls, you can use VoIP apps like WhatsApp or Skype over your WorldESIM data connection, ensuring you can still reach out when needed.
