Joanna Jesh Transport Corporation (JJT) is one of the largest city bus companies in the Philippines. Dubbed "The Twin Sisters" because of the company name fused together, it plies routes from Food Terminal Inc. (FTI) Complex, Taguig City to Navotas City.
Joanna Jesh Transport was taken from the names Joanna and Jessa. The eldest was said to be named Joanna Marie de Guzman Mahilac, while the second one was Jessa de Guzman Mahilac. These were the daughters of Crisinciano E. Mahilac, sole founder and owner of the company.
Founded in 2003 by Crisinciano E. Mahilac, a former Overseas Filipino Worker (OFW) in Saudi Arabia (where the trademark KSA is found inside the bus units), the company started to operate 8 Japayuki buses and 2 ordinary buses for FTI-Navotas route. But the company decided to change these units into all ordinary buses when the company bought two ordinary Daewoo buses, and later, 14 UD Nissan Diesel and 4 Hino ordinary units (in addition with its only one Japayuki unit, which was converted into ordinary). There were additional 10 bus units (UD Nissan Diesel and Hino) which were named as Amtrak Transport Inc. (but the name changed after the serious road accident), plying Baclaran-Navotas route.
