In 2019 MIE Racing participated in a joint project with Honda and Althea Racing, entering the FIM WorldSBK Championship with an HRC factory-supported team, the Moriwaki Althea Honda Team, and fielding experienced British rider Leon Camier and Japanese rider Ryuichi Kiyonari.

MIE Racing founder and Team Principal Midori Moriwaki managed the project. Though challenging, the 2019 season allowed MIE Racing and Honda to gain important experience in view of the 2020 season.

In 2020 MIE Racing confirmed its firm commitment to the FIM WorldSBK Championship in entering the series with the satellite MIE Racing Honda Team AND 2017 MFJ*3 All Japan Road Race Championship winner and factory HRC rider Takumi Takahashi.

In 2021  MIE Racing Honda Team announced Leandro Mercado as its rider for the 2021 Superbike World Championship aboard the CBR1000RR-R FIREBLADE. The former 2014 Superstock 1000 champion has regularly demonstrated his ability to quickly adapt and be fast aboard different machines. 29 years old, he is an experienced rider whose race career has spanned different categories, including six seasons in the Superbike World Championship.
