Bandai, Medicom and other Japanese toy companies have some ties, Probably hard to break in, I guess.
However, it could have been much better if Hot toys had a more knowledgeable director and more aggressive marketing strategy. They just made some bad choices for first few figures.
Technically, Kerberos is Live-action Concept figure. They also had Kamui figures from Live action film.
The thing is that City Hunter was huge in Hong-Kong before it became part of China) My guess is that it was Howard Chan's personal favorite license. It wasn't so big elsewhere - And they made a bad assumption about the sales - and it ended up in bargain bin - probably gave Hot toys the idea 'stay away from Anime figures'
I remember some 3rd party made 2 figures (live-action version of Sanji and Zorro) and didn't do well. Hot toys wouldn't make that type of toon characters. Can you imagine they make 1/6 Simpsons figure line?
That's why they need a marketing director who knows what's popular and where in Anime licenses and control the sales expectation..etc.
In US, for example, Ninja Scroll and Voltron was popular. In Japan, they weren't so hot.
In Europe, Go Nagai robot series was huge, but not in US.
