JR-Freight KoKi 100 series container wagon

The Koki 100 series is a container car of JR Freight, which was introduced in 1987. The floor height was lowered to 100mm and the maximum speed is 110km/h. The current collection includes the KoKi 104, of which more than 2,000 cars have been produced since 1989, the KoKi 106, which has been produced since 1997 for use with marine containers, and the KoKi 107, which has been produced since 2006 as the next-generation model.

It also includes 12ft, 20ft, and 31ft containers to be loaded on Koki 104, 106, and 107. Koki 106 and 107 require the Cargo Asset Set to carry ISO 20ft and 40ft containers.

April 2022 update: Koki 104, 106, and 107 can now also carry steel and construction materials. Lumber and planks can also be transported by Koki 106 and 107 using ISO containers. When carrying a loaded ISO container, only two are loaded due to weight restrictions.

As of the June 12, 2022 update, in KoKi 106/107, fuel, oil, and crude oil can also be transported in tank containers. At the moment, only one 20ft tank container is loaded.

The October 8, 2022 update adds a Koki 104 ISO shipping container loader. It will be marked with an "M" and will be available from 1996 to 2002. For now, it will not carry JR containers, but only the ISO shipping containers included in the Cargo Asset Set.
