Because this name, Mototsugu, is not found in other records, it is generally considered a previous name of Motomasa; however, there are other opinions including that Mototsugu was an older brother of Motomasa, Mototsugu was in fact Shiro (a father of Onami) who was a younger brother of Zeami, or that Mototsugu was the same person as 'Goro KANZE' recorded as a person who performed with Onami.
この元次は他に記録に名が見えないため、元雅の前名とするのが一般的であるが、元雅の兄とする説、世阿弥の弟である四郎（音阿弥の父）とする説、音阿弥の共演者として記録に名の見える「観世五郎」と同一人物視する説もある。
