Trust me when I say that you should take down the JP site immediately. Your friend might be "native-Japanese," but he or she is only directly translating your text from English.

The biggest part might be simply that you are not incorporated inside of Japan. It's fine to state your fondness of Japanese culture to the JP press, but if you want to get serious about Japan, get incorporated and let your Japanese 代表 ("daihyou") take care of things for you.

The worst thing you could do in Japan is release a (in your words) "Work in Progress." Keep things that are incomplete in the labs and refine them until they are ready for society to enjoy. Japanese society is all about keeping risk low for oneself, one's partners and especially the general public.

If you are really serious about Japan, feel free to drop me a line. If you really think that directly translating English to Japanese will add value to your company, you are gravely mistaken.

Remember to manage your customer's expectations. If they expect you to be a Japanese company and you are not one, you are in for a world of hurt.
