Trust me, I know what a haiku is; they
are Japanese to begin with.
The ones I posted are 5/7/5. You just have to understand how Japanese syllables work. Tenjou for example is a 4-syllable word in Japanese. TE-N-JO-U. The extended vowels—and that solo N—are syllables on their own. Haiku in Japanese are written using these sounds in 5/7/5 pattern—not Western style syllables.
There
are actually other types of haiku (including types of poems that are longer, and involve haiku in them), however mine are of the standard 17-syllable (or perhaps better said 17-
on) variety.
The wiki entry has lots of information on haiku, and other similar forms of oriental poetry.
The poems again with the Japanese syllables separated:
MO-U FU-YU DA
A-RA-TA NA A-NI-ME
GA KI-TE-RU YO
YA-RI-YA-SU-I
HA-I-KU O KA-KU NO
KO-RE DE I-I
YA-RU ZE-N-BU
TE-N-JO-U NE-KO GA
MI-TE-I-RU ZO
