Popular actors who were former students in Gokusen

Casting director of Gokusen is insane. Imagine casting 3 batches of relative unknowns who would go on to become highly successful actors. There must be a blessing that comes with being casted in Gokusen. Whenever I rewatch I get excited spotting big stars now that were just students with no speaking lines in the background.

Gokusen 1:
Matsumoto Jun
Oguri Shun
Narimiya Hiroki - retired from entertainment

Matsuyama Kenichi
Wentz Eiji
Tanaka Kei - student of diff school

Gokusen 2:
Kamenashi Kazuya
Akanishi Jin
Motomichi Hayami
Koide Keisuke - cancelled

Mizushima Hiro
Kengo Kora

Gokusen 3:
Miura Haruma - RIP
Ishiguro Hideo
Miura Shohei

Movie:
Kento Kaku

Also I feel like Mizobata Junpei is in 2? But I couldn’t find any credits

On a different note after another rewatch of Hana Yori Dango Returns I realized Omasa Aya plays one of the Eitoku students.
