The 3000 words nadiatims mentions are more than adequate to allow a person to be comfortable in conversation. Not quite enough to function well in a work environment, but quite enough to allow one to move to a country and live there. If the level they reach is not adequate, it's not because they lack the vocabulary, but because they can't use it. Besides, it'd be difficult to teach more words than that: it's more than 5 words an hour. That's fine for passive acquisition, but not for active use.
While I'm no specialist on ESL education in Japan, I do know that the purpose of high school English classes is not to make people fluent, but to allow them to pass entrance tests. And for that, it's adequate. But as far as actual proficiency is concerned, it's crap. And it has nothing to do with vocabulary size.
