I really don't have much info on this song, other than it is a training song.
Lyrics: (May not be 100% accurately transcribed)
nippondanshi to umare kite
sen no ba ni tatsukara wa
na o koso oshime bushi yo
chirubeki toki ni kiyoku chiri
mikuni ni kaore ōka.
nasake ni atsuki jōbu mo
tadashiki ken toru toki wa
zenman'nin mo jisuru nashi
shinzuru mono wa tsuneni kachi
sumeragi-shi ni mukau teki araji
Gojō no kun kashiko mite
sen'ya ni shikabane sarasu koso
bujin no kakugo mukashi yori
ichi kami tsuchi ni nokosazu mo
Homare ni nan no shi Ya aru.
