The Hanshin Expressway Loop Route
Located in the very heart of downtown Osaka, the Hanshin Expressway Route 1 Loop Line (commonly known simply as the "Kanjo Loop") is a 10.3-kilometer clockwise circuit of elevated urban highway. While Tokyo has the Bayshore Route (Wangan) famous for its top-speed, high-horsepower runs, Osaka's Kanjo Loop is entirely different. It is tight, highly technical, and deeply entrenched in local lore as the undisputed home of the Kanjozoku—Japan's most infamous underground street racing subculture.
The Kanjozoku & The Honda Connection
Unlike other regions that favored powerful inline-sixes or rotary engines, the Kanjo Loop has always been dominated by one specific platform: the Honda Civic.
Since the late 1980s and 1990s, local racing teams (with names like No Good Racing, Temple Racing, and Law Break) adopted the Civic—specifically the EF9, EG6, and EK4/9 chassis. Why? Because the Kanjo is incredibly tight. It demands a chassis that is lightweight, stops on a dime, and possesses razor-sharp agility to weave through complex interchanges. These teams took heavy inspiration from the Group A and "One-Make" Civic races happening at the nearby Suzuka Circuit, bringing those stripped-down, loud, and highly functional racing setups directly to the Osaka streets.
The Circuit Characteristics
Driving the Loop legally today still gives you a clear understanding of why it became such a legendary proving ground.
-
The Layout: The course weaves directly through the densely packed skyscrapers of central Osaka (passing through wards like Naniwa-ku and Kita-ku). The road width changes constantly, and the surface features challenging elevation changes and oddly shaped, off-camber corners.
-
The Driving Dynamic: It requires specialized cornering techniques and rapid acceleration rather than just holding down the throttle. The transitions from short, high-speed straights into sudden, narrow hairpins make it feel more like a massive, elevated go-kart track than a traditional highway.
