History
Ten'yaba Station opened on 14 March 1992 as a station of the Mooka Railway, in the Kitatakaoka district of the town of Motegi in Haga District, Tochigi Prefecture. Motegi sits in the south-east of Tochigi on the border with Ibaraki Prefecture, where the Naka River flows through the town and salmon ascend the river — making salmon one of the town's local specialities. The current Motegi was formed on 1 August 1954 by the merger of the former Motegi-machi with the villages of Sakagawa, Nakagawa and Sudō.

Notes
The Motegi article notes that the Mooka Railway's ancestor — the Mōka Light Railway — was extended to Motegi as far back as 15 December 1920 (Nanai–Motegi section), and that the rail-end town later became the site of the 1997 opening of Twin Ring Motegi (the motorsports facility renamed Mobility Resort Motegi in 2022).
