I recommended avoiding IMO Talent Agency due to my less-than-favorable past experience with them, but are there any good talent agencies for us foreigners here in Tokyo? I compiled a brief list:
While at an IMO job, I met a fellow American that pointed me in the right direction by referring me to Zenith. Zenith was a breath of fresh air―they asked for my bank account information when registering (a good sign they intend to pay), they paid me exactly 1 month after the job, and they're friendly and pleasant to work with.
I haven't registered with Avocado, so I don't have personal experience with them. However, I've heard from others that they're professionally-run and respectable. In fact, I believe they're run by foreigners frustrated by the questionable business practices of other talent agencies.
DAG Music is a talent agency primarily for musicians. I am finishing the registration process with them (I have to record my demo medley), so unfortunately I haven't done any jobs for them yet. Nevertheless, like the others, I was referred to them on the advice of fellow foreigners.
Ask others about the above agencies, and you'll likely hear positive things. I can't stress this enough--it's critically important to vet and validate when working in this under-regulated industry. Best of luck to you, fellow foreigner!
Thanks to a very kind reader, here are some more talent agencies that others report favorable experiences with
