Little is known about this contest, other than that it was clearly sponsored by Emperor Uda. One of its poems made its way into Fubokushō (XI: 4232), where it is conflated together with poems from the Teishi-in ominaeshi awase, but as that poem does not appear in that contest’s texts, it must be from a separate contest. Hagitani (1963, 107) suggests that this contest could have taken place at any time prior to Engi 延喜 13  with the most likely timing being a few years after Teishi-in ominaeshi awase in Shōtai 昌泰 1 .
The exact extent of this contest is also unclear, but it must have had at least ten rounds, of which only seven survive.
