According to the Jim Dunlop website :

Shin Suzuki is the most celebrated amp and pedal designer in Japan, renowned by tonechasers the world over for his ability to faithfully recreate some of the most elusive sounds in music history. As proprietor of Shin’s Music in Tokyo, he has cultivated an unfailing ear for incredible tones. In 2016, Shin collaborated with the MXR Custom Shop to create the Shin-Juku™ Drive, a pedal widely praised for the way it captured the raw sonic complexity of a rare amplifier with a legendary reputation. Shin and the MXR Custom Shop have come together once again to create the MXR Raijin Drive, a pedal that reinvents two iconic Japanese stompboxes—an overdrive and a distortion—with greater tonal range and usability so that those beloved sounds can keep up with the modern tone chase.

I can add to this that - Mxr already made also collaborations with other small pedal builders , like Carlo Sorazio (Il Torino Overdrive and Il Diavolo) . Working this way the non-american smaller builers can catch more attention to their product . However all these collaborations are only working for short term , and this one is no exception as it was discontinued few years ago .

Anyway , mine works perfect and looks good , and has the original box .
