Sadamine Pass

Sadamine Pass, also known as Sadamine Touge, is a mountain road in Saitama Prefecture connecting Tokigawa with Higashichichibu. This technical 8.5-kilometer circuit is famous for its extremely tight hairpins and steep elevation changes. It's part of the territory controlled by the Northern Saitama Alliance and is known for testing braking ability and control in slow corners.

Sadamine Pass has been an important mountain route in the Saitama region since ancient times. During the golden age of touge racing in the 90s, it became a preferred training ground for drivers looking to master slow corner techniques and precise braking. The Northern Saitama Alliance established their dominance here thanks to their deep knowledge of every hairpin and their ability to maintain speed through the tightest corners.
