Air Do (HD, Sapporo Chitose) will transfer four of its Sapporo Chitose routes to ANA - All Nippon Airways (NH, Tokyo Haneda) this summer the Zipanguflyer blog reports.

Citing poor demand, the Japanese domestic operator will transfer its Fukushima, Niigata, Komatsu, and Toyama services to ANA beginning March 29 with each to be downgraded to a single daily return flight. All flights will be operated by an ANA B737-800 with the exception of Niigata, which will be operated by an ANA Wings (EH, Sapporo Chitose) Dash 8-400.

Ironically, it was ANA that switched the routes out to Air Do in November 2009, preferring to codeshare on the flights instead.
