NHK Radio 2 (JOIB) started on September 3, 1945, while also providing facilities for an AFRS station (WLKD) later that month.
On March 3, 2021, regional programming (in an initial phase from the core stations) was added to NHK Plus.
[5] NHK was looking for a new location for its aging Sapporo Broadcasting Hall, which was built over 50 years ago, and initially considered moving to the adjacent Sapporo Sosei Square, but in March 2012, a redevelopment plan was announced.
A development plan was being considered based on six concepts: a hall that contributes to the development of local culture and connects with the people of Hokkaido, a hall that is friendly to people and the environment and takes advantage of Hokkaido's unique character, and a new sales call center.
