Other Yamamoto projects for Toei

[DB1984]

Besides Dragon Ball, what other stuff did Kenji Yamamoto do for Toei (Live-Action and Animation)?

All I know is that he was the music arranger for the opening and ending themes of Sentai Zyuranger.

I don't know how accurate this wiki is, but if it's anything to go by, he was quite active outside of Dragon Ball.

Japanese Wikipedia is usually fairly accurate about these sort of things. I guess I'll note what it says.

Chikyuu Sentai Fiveman:
Arranged the OP.

Choujin Sentai Jetman:
Arranged the ED and an insert song.

Gosei Sentai Dairanger:
Arranged the OP and ED.

Ninja Sentai Kakuranger:
Arranged the OP and ED.

Bakuryuu Sentai Abaranger:
The series BGM composer is a group called "Kentarou Haneda With Healthy Wings." It includes the namesake Haneda, Yamamoto, Kousuke Yamashita, Hiroshi Takaki, and Megumi Oohashi.
Yamamoto also arranged three insert songs, as well as composing two of those three.

Bishoujo Kamen Poitrine:
Arranged the OP and an insert song.

Magical Taluluto-kun:
Arranged the OP, both EDs, and seven insert songs.

Dr. Slump (Playstation game):
Composer.

Those are just the Toei projects (besides DB and Zyu). But he also did plenty of non-Toei work. I suppose I'll note those too in a spoiler cut, since I have the tabs open anyway, and it might interest someone.

Spoiler:

Kiteretsu Daihyakka:
Arranged OPs 1, 2, 3, and EDs 1, 3, 4.

Tenkuu Senki Shurato:
Arranged OP 1 and ED 1.

Madou King Granzort:
Arranged the OP and ED.

Yuusha Exkaizer:
Arranged the OP and ED.

B B-Daman Bakugaiden:

Harigumo Harley:

He also arranged a lot of songs for Hiromi Gou, some for Hironobu Kageyama, one for Megumi Hayashibara, and he arranged the official theme for the Fukuoka SoftBank Hawks baseball team.

I probably already know the answer to this question, but why wasn't Yamamoto involved with the DBZ Anime, after the opening and ending themes changed in 1993?

I don't know for sure, but that was around when he started composing lots of DBZ game music. Super Butouden 2 came out in 1993. Maybe he was just too busy, combined with his other TV work.

I heard that he had had some problems with Columbia Japan, so MONOLITH got broken up.
