Kinokuniya has started taking in pre-orders for school calendars of the various Johnny's groups! Drop by the customer service counter/ Japanese books section and you'd find a teeny weeny notice displaying the different groups as well as prices. Deadline for pre-orders is 14 Jan 09. Arashi's calendar (refer to lovely preview by ichaa) is going for SGD46.30, which is probably cheaper than ordering from most online places like yesasia etc.
Non-refundable deposit of SGD20 required. Collection period probably late March to early April.
