Ok I didnt go on day1 so I will just describe the layout for day2.
There are 6halls on East side. If that anon is right about 6 being touhou, so 4 & 5 are for fujoshis.
3 is 100% Touhou. 2 is for cosplay shit, you can see all lenfried fans lining up for heruheru3 and you can see girls wearing very revealing wresting clothes and other cosplay stuff.
East 1 is misc stuff, books, handmade crafts and other stuff.
Now lets move on to West1, 100% vocaloid.
In between West1 and West2, you can see get music, movie, games non touhou/original.
But the some of the huge popular circle will be in West like those breakaway Iosys circle.
West1 you get mostly yuri stuff and the extreme left you get to see your obaasan and aunties.
Now if you consider day1 as fujoshi day, what do you think about touhou presence in comiket?
