According to Kojiki, it is said that he wrote a poem "Kunishinobi uta" (a song to remember the country) with thinking of Yamato shortly before his death; this poem became very popular among soldiers dispatched to East Asia during the Pacific War.
なお、『古事記』によれば、死の直前に大和を懐かしんで「思国歌（くにしのびうた）」を詠んだとされ、この歌は、太平洋戦争中に東アジア地域へ派遣された兵士の間で大変流行ったという。
