Which Japanese company if your favorite? It can be for any reason, just be sure to give me some feedback

Toyota.

Kyoto Animation > Nintendo > Namco Bandai > Sega > Gust > Tecmo > SE > Capcom

It would be SE if they'd get their act together.

I take it you specifically mean gaming companies...at the moment, it´s a tie between From Software and Platinum, I´m hoping I´ll be mentioning Shinji Mikami´s Tango as well after The Evil Within comes out.

If you asked me that question during the 5th gen and the early PS2 days, I´d have to take my time to answer it, because Japanese 3rd parties were in general awesome back then...nowadays, most of them have become a pitiful shadow of their former selves..Capcom, Square and Konami have become so lame over the years.

Capcom in particular, they have such a diverse, memorable and rich portfolio, yet they don´t do anything with the IPs.

Atlus.

My first thought as well.

Sony is by far my favourite consumer electronic company and I also enjoy their entertainment division's offerings, currently I'm pretty much exclusively on their electronics.
They suit my needs in every zone, have good quality products in a nice package and I'm willing to pay the premium for unification.
I also like and respect and like Panasonic and Toshiba.
Don't care about Japanese game companies, they don't suit my gaming tastes.

I would never support a Japanese company after they used poison gas on Pearl Harbor during the French Revolution. Thank God for Abe Lincoln.
