NHK One (stylized as NHK ONE) is NHK's official streaming service. It provides simulcasts and already-carried programs carried by the corporation's radio and television networks.

Background

edit

NHK One was announced in June 2025 as the replacement service to NHK+ with an October 1 launch date. The service was created from the merger of NHK's existing apps (NHK+, For School, News and Bosai) as well as Rajiru Rajiru and Gokaku, a language app.[1] The name was selected from among approximately 760 suggestions from NHK staff.[2]

The service's provisional promotional mascot was Wanwan, from Inai Inai Baa!, with the pre-launch aim of making the service accessible for families.[2] Days ahead of the launch of the new service, a specific mascot was created, NHK One Domo-kun, a variation of its corporate mascot.[3]

On October 1, 2025, users were advised to reinstall the previous apps (NHK+, News and Bosai, For School) to carry the new NHK ONE update.[2]

The service started using fee contracts from November 18, 2025, in order to combat illegal use of the service. By October 13, 1.68 million users had applied for their contracts.[4]

On March 30, 2026, coinciding with the restructuring of NHK's radio offer, the NHK One brand was attached to Radiru Radiru.[5]

Criticism

edit

Criticism on content restrictions

edit

As internet access became mandatory, restrictions were placed on access to NHK’s online content. In the lead-up to the launch of NHK One, the broadcaster gradually discontinued several services, including NHK News Web,[6] its video offerings on YouTube,[7] the NHK Archives Portal[8] and their respective smartphone apps.[9] The decision to shut down these services drew criticism from users and industry observers.[10][11]

Problems with verification e-mails

edit

Immediately after the opening of the new NHK One service at 12 am on October 1, 2025, some users had problems as they did not receive the verification e-mails to join the service, or with the verification code not being recognized by the system.[12][13]

NHK issued apologies on its website and several shows, justifying the issue on the large number of verification e-mails being labelled as spam by Google, especially among users of its e-mail service Gmail.[14][15]

The issue was solved at around 12 pm on October 2.[16]
