 With a great number of out-of-province Guests invited in 2009, Otakuthon was upgraded from a regional-level convention to a national-level one.2010 introduced a Thursday evening badge pickup option for pre-registered attendees, which alleviated the long lineups on Friday as well as provided them immediate access to the convention area when the doors opened on Friday afternoon.Year after year, Otakuthon has occupied more and more conference spaces and hallways of the convention center following an annual progressive growth; while in 2008 less than half of the 5th and 7th floors were booked, in 2010 nearly 80% of those floors plus the main exhibition hall of the 2nd floor (for Registration) were open for the convention.
