Rider naming scheme?
 

Has anyone else noticed that a lot of Riders have real names where their first name ends in an "oh" sound and the last name ends in an "e" sound or vice versa?

Takeshi Hongo

Hayato Ichimoji

Shiro Kazame

Yuriko Masaki (yes she counts)

Kotaro Minami

Shiro Mizuki

Shinji Kido

Masashi Sudo

Mutsuki Kamijo

Souji Tendou

Tsurugi Kamishiro

Ryotaro Nogami

Kotaro Nogami

Shotaro Hidari

Daiki Kaito

Eiji Hino

Gentarou Kisaragi

That's 17 riders with this little trait in common. Is this a coincidence or is it a deliberate homage to the man who created Kamen Rider: Shotaro Ishinomori?

Or am I going crazy?

pretty sure it's just because Japanese is such a vowel-centric language and there are only 5 Vowel sounds.
