The new unit Super Junior-83z of Super Junior has been attracting attention even before their debut. Super Junior-83z, consisting of Leeteuk and Heechul, is scheduled to hold a fancon tour '1983' in nine regions across Asia ahead of their official debut in July.

The Super Junior-83z fancon tour will take place in Seoul, Tokyo, Bangkok, Hong Kong, Kuala Lumpur, Macau, Kaohsiung, Singapore, and Taipei. The Seoul concert was originally scheduled to be held at Olympic Hall in Olympic Park, Songpa-gu, from July 25 to 26, but due to all tickets being sold out for every show, an additional performance on the 24th was added. As a result, there will be a total of three performances in Seoul from July 24 to 26.

Tickets for the additional July 24 performance will be available through Melon Ticket, with pre-sale for Super Junior official fan club E.L.F. membership starting at 8 PM on the 29th, and general sales beginning at 8 PM on the 30th.

Super Junior-83z is a unit formed by Leeteuk and Heechul, who are the same age, both born in 1983.
