Woah! In 2006, Kozo Sugino invited Mo from Keirin Berlin to check out all that Japan had to offer in terms of NJS framebuilders. He went to Osaka to meet the amazing Nagasawa-San, then the late Doi-San of Ganwell Pro before visiting the Sugino factory to meet with Kozo Sugino.
Finally, he headed up to Shuzenji to see the Keirin school and further up north with the Shinkansen to Tokyo to see MKS, Nitto and meet Tanabe-San at Kalavinka.
This looks like an insane trip!
