I've seen him in some movies and want to watch more of him, what is/are the best shows with Takeru starring as ML! 

<3 

My personal top 3: 

Bitter Blood (great comedy)

Tenno no ryoriban (probably the best tv drama I've seen him in)

Kamen Rider Den-O (if you're into tokusatsu, Den-O is really fun)

Thank youuuuuu!!!!

I liked him in An incurable case of love/love will last forever

He also acts in

Rurouni kenshin LA

The liar and his lover
