-Ame ni mo Makezu-
ame ni mo makezu
kaze ni mo makezu
yuki ni mo natsuno atsusa ni mo makenu
jobu na karada wo mochi
yoku wa naku
kesshite ikarazu
itsumo shizuka ni waratte iru
ichinichi ni genmai yon go to
miso to sukoshi no yasai wo tabe
arayuru koto wo jibun no kanjo ni irezu
yoku mikiki shi wakari
soshite wasurezu
nohara no matsu no hayashi no kage no
higashi ni byoki no kodomo areba, itte kanbyo shite yari
nishi ni tsukareta haha areba, itte sono ine no taba wo oi
minami ni shiniso na hito areba itte kowagaranakute mo ii to ii
kita ni kenka ya sosho ga areba, tsumaranai kara yamero to ii
hideri no toki wa namida wo nagashi
samusa no natsu wa oro-oro aruki
minna ni deku-no-bo to yobare
homerare mo sezu
ku ni mo sarezu
so iu mono ni watashi wa naritai
