While the 'Shin-shui wakashu' (the New Collected Gleanings (of waka poetry)) was still in the middle of being compiled, its compiler, Tameaki NIJO, passed away, so Tona took over for him and completed the work; at the time he became compiler, he was 76.
「新拾遺和歌集」撰進の際には撰者二条為明が選集の途中で亡くなったことから、頓阿がそれを引き継いで完成させたが、撰者となったのは76歳の時である。
