I just posted an article on Asiajin on GREE having announced the opening of an office in San Francisco.
Read it here: GREE opens subsidiary in the US.
If GREE succeeds in the US, it would be the first web company from Japan in history. I am skeptical personally, but I am even more skeptical of DeNA’s decision to pay $400 million for ngmoco – even though both companies have done more than a great job so far in their home market.
