Are you joking? I don't know what's funnier, that you think a Naruto movie would only sell a thousand copy in Japan, or that a Berserk movie would outdo Naruto 10:1. Either way it's ridiculous and I'm asking you to stop posting nonsense.
It's a little more than 1,000 but I said so since Bleach stopped selling that much. Let's make 3000 the approximate number of sales for one Naruto and Bleach release
I was speaking about Naruto anime in general not movies.
Here's some previous sales of Naruto and Bleach

Yes most of them are first week sales, but they rarely appear in the rankings after that, so they couldn't have sold that much.
For movies they sell more though, I know Bleach once sold 20,000 for it's 4th movie and Naruto sold 12,000 + for it's latest movie Blood Prison
