The amount of influence that Amemiya-san has in the field of tuning Mazdas, specifically the RX-7, is arguably untouchable. The popularity of his designs and the overall originality of his creations are known not just throughout Japan, but the entire world. Walking through the showroom of Isami’s flagship shop in Tomisato, Chiba, you’re given proof of how much weight the name carries. Trophies from race events, car shows, and manufactuer recognition are plastered from one wall to the other. Momentos of achievement past and present line the glass cases along the walls of the showroom, surrounding the beautiful blue, Super GReddy clad demo car sitting front and center.
