Buy a Phone in Japan

New or used, from a carrier or unlocked — how buying a smartphone works, and how it connects to your contract.

Menus, labels and guide explanations are available in the selected language. Carrier names, plan names and other proper nouns may remain in their official form.

Where phones are sold

  • Carrier & sub-brand shops — sell devices tied to a contract, often with installment plans and campaigns.
  • Carrier online stores — same devices, shipped to you or set up as an eSIM.
  • Electronics retailers — sell both carrier devices and SIM-free (unlocked) phones.
  • Manufacturer & unlocked — buy the phone outright, then choose any compatible plan or SIM.
  • Used / refurbished — check the network bands, battery, and that it is not payment-locked (赤ロム).

하나의 청구서에 두 개의 별도 항목이 있습니다. 분할을 이해하면 캠페인을 훨씬 쉽게 읽을 수 있습니다.

A device bought on installments is a separate agreement from your mobile service. If you cancel the service, the remaining device balance is usually still owed.

Bands & compatibility

A phone works best if it supports the frequency bands of the network you choose. Devices sold by a Japanese carrier are tuned for that carrier. An unlocked phone bought abroad may work but can miss some bands — check before you rely on it.
