It's a kendo school run by Japanese police and that is
all over the country.
The teachers are also policemen.

Never heard that they train their brain.
Well, maybe there's no such teacher among them.

警官が集まって 「 ヤアー!トオー!」 剣道のおけいこ。
いつものこと。
警官の有段者が先生。
頭のおけいこは?
いやっ!無理か!
先生がいないか・・
It's insane
not to train
your brain.
It's your strain
and pain
that you gain
if you don't train
your brain
despite rain.
You drive in pain
in the empty lane
or fly in vain
on the plane
if you don't gain
your brain.
No gain?
Try again
in the rain
and
stay sane.
