Bloomberg "about 2,000 people" lined up at store in Akihabara, a shopping area in Tokyo, in hopes of obtaining a 3DS after electronic retailers sold out on pre-orders alone.

Reuters customers were also lined up at a camera store in Yurakucho, Tokyo, though didn't offer estimates (much of the story's dedicated to frowning on the 3DS's chances in light of tablet and smartphone alternatives).

And The Wall Street Journal "hundreds of people" lined up outside a store in Ikebukuro, Tokyo, with the "line snaking around the building." The WSJ also notes people lined up outside multiple Tokyo stores the night before.

Adult anime and manga site Sankaku Complex that's apparently compiling Twitter dispatches from fresh 3DS owners complaining about (though also praising) the 3DS's 3D mode. One person claims to suffer eye pain after playing for five minutes, with others mention taking breaks after experiencing eye "tiredness" or "soreness." It's way too early to read these as more than anecdotal, but it'll be interesting to watch--both how Japanese gamers respond to the technology, and how the Japanese media handles reports of issues with it.
