::Which of the several other web pages were you thinking of? The first one listed was a discussion of Chinese units, not Japanese, and the next 2 were broken links, followed by the Japanese wikipedia article and a newspaper article about the size of priests' rooms. Given the nature of wikipedia, I don't think it's a terribly good idea to regard another wikipedia article as being an authoritative reference. Your method of pointing others to vast amounts of Japanese text, only a small part of which is relevant, comes across as a way of boasting how much better your Japanese language skills are. If you want to cite an article to back your views, by all means cite one that is relevant. But that link admirably demonstrates the weakness inherent in relying on a search engine. By teh logic you used, any search for weights and measures in teh English language would only ever find English language units, which plainly isn't true by virtue of this discussion we are having.
