NHK WORLD-JAPAN Radio begins shortwave for Iran

2 March 2026

In light of recent developments in the situation in Iran, NHK has begun temporary shortwave transmissions of its Japanese language international radio service, NHK WORLD-JAPAN Radio. NHK’s mission as an international public service media has led to this initiative to provide essential information to Japanese nationals residing in or travelling in the region.

Following the attacks on Iran by the United States and Israel, Internet connectivity and international telephone services in the region have become unstable resulting in limited access to information in Japanese. In response NHK has begun temporary shortwave transmissions of its Japanese language international radio service to provide essential information to Japanese nationals in the area the broadcast started at 11:30 AM Japan time (0230 GMT) on 1 March.

NHK normally broadcast six hours of shortwave programming every day to the Middle East. However, in view of the current situation the broadcast schedule has been expanded to provide a continuous 24-hour service. In addition to content from NHK Radio 1, the broadcasts will include safety and security information for those in the region.

For those in neighbouring countries or other areas where Internet access remains available NHK also provides Japanese language news on the NHK world Japan website, along with simultaneous and on demand streaming of its television and radio programmes.
