Why no Samsung laptops in Japan?

I keep seeing these reviews of wonderful looking Samsung series 9 laptops, but can't find any purchasing information on amazon.co.jp, and there's no mention of Samsung laptops on their Japan website. The Japanese wikipedia article mentions that Samsung made a decision to pull out of sales of home appliances in Japan due to poor sales figures, but I didn't see any specific mention of personal computers.

Is there perhaps an exclusivity deal with a Japanese computer maker that they supply components to? Or is not selling laptops in Japan linked with pulling out of the home appliance market. Anyone know why I can't get a series 9?
