It's a pretty lively gathering. A group of eikaiwa teachers are noisily denouncing their employers, while nearby a pair of leery Charisma Men are swapping tales of sexual conquests, and next to them some language students are loudly debating the Yasukuni Shrine.
Almost lost among the din, is another group in the corner quietly discussing Haruki Murakami's latest novel.
No, not a night out in the Shibuya Cat and Fiddle, just a brief visit to one of Japan's English language discussion boards.
