Where Ko-Uda closes with the Nanbokuchō generations, the chapter that follows opens in early Muromachi and runs to the end of the period. The setsumei draw the boundary plainly: works that descend no later than Nanbokuchō are called Ko-Uda, while everything thereafter is referred to simply as Uda. This later phase is the long Muromachi continuation in Etchū, where the Kuni-named line that began with Ko-Nyūdō Kunimitsu of Uda District in Yamato extends across successive generations sharing single names.
