Best way to find jobs in Japan from the US (as someone who moved to US from Japan as a fresh grad)

Hi guys,

Have a question.

I moved to the US from Japan as a fresh grad for a job. I worked 2 years in one company and now on my 2nd company. Both are Japanese companies that has it's headquarter in Japan (first one being the restaurant equipment industry, current one in entertainment/anime industry which I really like).

Down the line I plan to moving back to Japan, within 2-3 years, but I have no job experience in Japan, only part times.

I went to Japanese elementary school and the went to international. My Japanese speaking and writing (emails) are perfect. My English isn't fluent but business level, I don't have any problem socializing or working or getting by in LA.

What are some good ways to land a job in Japan from the US? Im 28, so thinking of moving back by the time Im 30. Im in sales, have no certificates or specific skills other than college in Japan.

I know the work culture is worse and the pay is lower in Japan, but I need to move back with the given circumstances (family and partner).

I want it to be as safe as possible, so I dont end up quitting few months in or get rejected due to some reasons. Open to building any necessary skills too.
