正月が過ぎたら まわしを しめなよ
2月が来たなら すもうを とりなよ
もしも君が 出不精でも
逆に外へ 出たがりでも

8月が来たなら 土俵へ おりなよ
いろいろ忘れて しこを ふみなよ
ビーチが君を 誘ってきても
セミがふ化して 夏に飛んでも


shougatsu ga sugitara mawashi wo shimenayo
kitaki ga kitanara sumou wo torinayo
moshimo kimi ga debushou demo
gyaku ni soto he detagari demo
oretachi wa itsudatte sou sa

hachi gatsu ga kitanara dohyou he orinayo
iroiro wasurete shiko wo fuminayo
Beach ga kimi wo sasottekite mo
semi ga fukashite natsu ni tondemo
oretachi wa itsudatte sou sa


When the new year is here, tighten your mawashi!
When February comes, do some sumoing!
Even if you're always lying around,
Or even if you like going out on the town,
That's how we'll always be!

When August comes, step into the ring!
Stomp your feet and forget everything!
Even when the beach beckons you to drop by,
Even when cicadas hatch in the summer and fly,
That's how we'll always be!

Song Production Information

There's another version of this song.
Originally, the lyrics were so vulgar that we couldn't post them, but we reluctantly made them somewhat more normal.
I'd love to see your expressions when you find out what they were originally supposed to be, haha.
I love this song! Why not make up your own lyrics to it, too?

Video Production Information


Melodic core is here!!
Stomp your feet! How does it feel!?
It's supposed to be a sumo song, yet the singer sounds like a cool youth in the same style as J---ny's!!
The lyrics are so weird, yet sound refreshing...
What are those yells?
The sound of sumo wrestlers surrounding the cool youth on a beach? "KOI!"
The song is hot even in the winter!
It's "hot" in many different senses!
It's really interesting, but you probably shouldn't think too hard about it...

Staff Comments


Alright... it's almost time to do some sumoing, isn't it?
