With "Korotsua" starting from today, 試遊 table of Smash Bros. 3DS has come out. Person near you please by all means. Today Shiga Prefecture. It seems to be accepted until 16:00.
Refer to my above best guess for the translation.
"With "Korotsua" starting from today" = "With the Corotour starting today"
"試遊(basically demo, from what I can gather) table of Smash Bros. 3DS has come out" = It'll have have a 3DS demo kiosk.
"Person near you please by all means." = If you're near it, feel free to go to it.
"Today Shiga Prefecture." = It (Corotour's starting point) is in the Shiga Prefecture.
"It seems to be accepted until 16:00." = Until 4:00PM.
Combined with the second tweet, the it seems he's intent on clarifying that the final version is much more polished than these demo versions everyone is playing.
The big things I'm taking from this are that Sakurai is definitely connected with Corocoro (not that that's all that important... just a thing to keep in mind) and that the final version
will be different enough from the E3 version for Sakurai to mention like that.
