Tekkoshocon moved to the larger David L. Lawrence Convention Center in 2009 and for 2010 expanded into a four-day convention. In 2011 due to the lack of available space at the David L. Lawrence Convention Center, the convention moved to the Wyndham Grand Pittsburgh Downtown (formerly Pittsburgh Hilton). The convention celebrated its tenth anniversary and remained at the Wyndham Grand for 2012 while adding a fifth evening of events offsite at the Hollywood Theater Dormont. Due to various issues (crowded staircases, hotel issues, noise complaints including an early shutdown Sunday morning), the convention announced that it would not be returning to the Wyndham Grand for 2013. Tekkoshocon Inc. transferred its property to the Pittsburgh Japanese Culture Society, a non-profit organization, in September 2012. The convention returned to the David L. Lawrence Convention Center starting in 2013, with the name shortened to Tekko for 2014.
