Naze naze
Kokoro ga itamu to namida ni naru
Naze naze
Namida ga ochiru to hitori ni naru
Chīsana hiza kakae
Tōku o mata miageru
Hiroi hiroi kono sora yori
Motto hiroi hazu da
Takai takai ano kumo yori
Motto takai hazu da
Kimi no kokoro mo
Naze naze
Kokoro o hiraku to egao ni naru
Naze naze
Egao o miteru to yūki ni naru

Ōkina yume kakae
Tōku o mata miageru
Hiroi hiroi kono sora yori
Motto hiroi hazu da
Takai takai ano kumo yori
Motto takai hazu da
Tōi tōi ano hoshi yori
Motto tōi hazu da
Yukō yukō ryōte hiroge
Kitto yukeru hazu da
Kimi no kokoro mo
