Iroha

Iro wa nioedo
Chirinuru o
Wa ga yo tare zo
Tsune naran
Ui no okuyama
Kyō koete
Asaki yume miji
Ei mo sezu.

Meaning:
As flowers are brilliant but [inevitably] fall,
who could remain constant in our world? [No one could]
Today let us transcend the high mountain of transience,
and there will be no more shallow dreaming,
no more drunkenness.

A perfect pangram, containing each character of the Japanese syllabary exactly once
