We'll start selling tickets for the conference on Tuesday, March 25th 10:00am JST (= 1:00am UTC). Payments are made online using PayPal, so there's no actual paper tickets and all you need is your credit card.
The price of the tickets are 3,500 JPY for the early-bird payments (first 7 days) and 3,000 JPY for students (You need a proof of your studentship at the venue). This fee includes an access to all sessions and a schwag bag.
The # of available tickets is about 300, and we had a record of selling 300 tickets about in a week last year, so don't get late!
Note that the speakers and volunteer staff are not required to purchase the ticket.
