Lyrics:
1.
Ware wa kan gun wagateki wa
Tenchiirezaru choutekizo
Teki no taishou taru mono wa
Kokon musou no eiyuu de
Kore ni shitagou tsu wa mono wa
Tomo ni hyoukan kesshinoshi
Kijinni hajinu yuuaru mo (sometimes written as "Kishin ni hajinu yuuaru mo")
Tenno yurusanu hangyaku wo
Okoseshi mono wa mukashi yori
Sakae shitame shi arazaru zo
Teki no horoburu sore made wa
Susume ya susume moro tomo ni
Tamachiru tsurugi nuki tsurete
Shisuru kaku gode susumubeshi
2.
Mikuni no fuuto mono no fu wa
Sonomi wo mamoru tamashii no
Ishiin kono kata suta retaru
Nippon to no ima sara ni
Mata yo niizuru mi no homare
Teki mo mika tamo moro tomo ni
Yaeba no moto ni shisubeki ni (Sometimes written as "Yaeba no shita ni shisubeki ni")
Yamato-damashii aru mono wo
Shisubeki toki wa ima naru zo
Hi toni oku rete ha jikaku na
Teki no horoburu sore made wa
Susume ya susume moro tomo ni
Tamachiru tsurugi nuki tsurete
Shisuru kaku gode susumubeshi
