The Suzuka 8 Hours is returning to the calendar this year after being cancelled in both 2020 and '21 due to the COVID-19 pandemic.
Six-time World Superbike champion Jonathan Rea will spearhead Kawasaki's assault as the manufacturer aims to score back-to-back wins following its triumph in 2019.
There will be no factory team from Yamaha at Suzuka, but it will be represented by a slew of outfits including EWC regular YART.
Honda's factory line-up will be led by its new WSBK signing Iker Lecuona, while Suzuki will also have sizeable presence at the race.
