Tomo-Dachi was an anime convention based in Derry, Northern Ireland. Starting in the summer of 2005, Tomo-Dachi was the first anime convention to run in Ireland. The original venue was The Nerve Centre, on Magazine Street in the city centre of Derry. Tomo-Dachi, also known as TDXX (the "XX" is replaced by the year - such as TD05, TD06, etc.) is now held annually at the Magee College of the University of Ulster. The name of the event comes from the word tomodachi (友達), which means "friends" in Japanese.
