I believe he means the worldwide sales for this week which show as 788,311. Not total sales in Japan, which happen to be 810000 according to the front page. I was also not sure which was going to be talked about until I read the first post. (I don't usually pay much attention to the regional totals)
Anyhow, I think it's possible. They've certainly been picking up some steam in Japan this year.
