Additionally, there is folklore in one of the Goto Islands, Uku Island in Nagasaki Prefecture, that, to elude the hunt for remnants of the defeated Heike clan after the Battle of Dan-no-ura, a younger brother of Kiyomori by the name of TAIRA no Iemori migrated to Uku Island under the assumed name of Jiro-Iemori UKU becoming the forefather of the Uku clan (the Goto clan).
なお、長崎県の五島列島宇久島には清盛の弟の平家盛という名の人物が壇ノ浦の戦いの後、落ち武者狩りを逃れて移り住み、宇久次郎家盛と名乗って宇久氏（五島氏）の祖となったという伝承が残っている。
