How to Dial Japan From the US

Cost Comparison: Calling Japan

LINE is Japan's most popular messaging app — far more common than WhatsApp. Install LINE if you regularly call Japan.

Best Time to Call Japan

Japan is in Japan Standard Time (JST, UTC+9). Japan does not observe daylight saving time.

  • 14 hours ahead of ET: 9 AM in New York = 11 PM in Tokyo (same day)
  • 17 hours ahead of PT: 9 AM in Los Angeles = 2 AM next day in Tokyo
  • Best window from ET: 7-9 AM ET = 9-11 PM JST (evening in Japan)
  • Best window from PT: 4-6 PM PT = 9-11 AM JST (morning in Japan)

    • The large time difference makes scheduling tricky. Early US mornings or late US afternoons work best for catching Japan during waking hours.

    Tips for Calling Japan

  • Use LINE, not WhatsApp: LINE dominates in Japan with 95 million users. Most Japanese people prefer LINE for calls and messages.
  • Business etiquette: Japanese businesses expect formal greetings. State your name and company before your request.
  • Avoid New Year: December 29 to January 3 is the biggest holiday period. Most businesses close.
  • Mobile numbers are personal: Japanese people may not answer calls from unknown international numbers. Text or message via LINE first.
