Japan Server - this place is totally revved up for Halloween!
There is a costume event going on in Central Plaza. Not sure if it unlocks rewards if you dress appropriately during the schedule, but I think it unlocks affects? You can wear the pumpkin mask during the devil time. Here is the schedule (Japan times):
0:00 FORMAL TIME
3:00 DEVIL TIME
7:00 BEAST TIME
11:00 WING TIME
15:00 FORMAL TIME
19:00 DEVIL TIME
23:00 BEAST TIME

UPDATE - right now, it appears that dressing for the appropriate event unlocks special effects only. The Tekken 6 Jin costume (free from Threads) can be worn for the formal time, and your avatar will be surrounded by a bright red mist with glowing red eyes. Tried it yesterday and it looked pretty cool.
A "Trick or Treat" challenge starts Oct 21 -- more info to come (and hopefully some freebies/rewards).

Free Jack O Lantern mask with glowing red eyes @ threads
IREM Bon Festival:
1) There is a van parked there - talk to the lady to unlock a
food item (I think it's curry in a tin - apartment item).
2) Go to the free yukata lady (under the tent) - talk to her to get an
'Excalibur' sword (giant glowing sword you see everyone running around with). If you pick all the first options, you get the yellow one.
I don't think you can get more than one of these, but I think you might be able to trade it back in by talking to the shady tshirt guy upstairs???
Also, I got a
glowing paper item (under clothing, hand item) - I'm not sure if I got this from talking to the shady thsirt vendor at Irem or by visiting Central Plaza.
ALSO - I've been seeing people run around with
glowing devil horns. I think this might be a Hudson Gate prize (from the
dolphy races). Not sure if this is still available - going to check it out today.
