Kanji

馬が走ってく 馬が走ってく
でっかい鼻の穴おっぴろげて 馬が走ってく

馬が笑ってる 馬が笑ってる
でっかい口をおっぴろげて 馬が笑ってる

馬が飛んでゆく 馬がとんでゆく
両手両足おっぴろげて 馬が飛んでゆく

馬が手を振った 馬が手を振った
空の上からニカッと笑って 馬が手を振った

馬が歌ってる 馬が歌ってる
今日までそして明日からを 馬が歌ってる

Romaji

Uma ga hashitteku uma ga hashitteku
Dekkai hana no ana oppirogete uma ga hashitteku

Uma ga waratteru uma ga waratteru
Dekkai kuchi wo oppirogete uma ga waratteru

Uma ga tonde yuku uma ga tonde yuku
Ryoute ryouashi oppirogete uma ga tonde yuku

Uma ga te wo futta uma ga te wo futta
Sora no ue kara nikatto waratte uma ga te wo futta

Uma ga utatteru uma ga utatteru
Kyou made soshite ashita kara wo uma ga utatteru

Translation

The horse is running, the horse is running
It’s large nostrils flaring, the horse is running

The horse is laughing, the horse is laughing
It’s large mouth open, the horse is laughing

The horse is flying, the horse is flying
It’s arms and legs apart, the horse is flying

The horse is waving, the horse is waving
Grinning from the sky above, the horse is waving

The horse is singing, the horse is singing
Till today and through tomorrow, the horse is singing
