Close

Along its 125.3-kilometer-long (77.9 mi) course, National Route 246 passes from Chiyoda through Minato, Shibuya, Meguro, Setagaya in Tokyo (called Aoyama-dori (青山通り) or Tamagawa-dori (玉川通り) in part of this section), and into Kanagawa Prefecture, entering Kawasaki (Takatsu and Miyamae), Yokohama (Tsuzuki, Aoba and Midori), Machida (Tokyo), Yamato, Atsugi, Isehara, Matsuda and Yamakita (called Ō-yama-kaidō (大山街道) or Atsugi-kaidō (厚木街道) in part of this section). In Shizuoka Prefecture, it passes through Susono, Oyama, and Nagaizumi en route to its terminus in Numazu.

Part of the route – running through Shibuya and past the outer gardens of the Meiji Jingu – was recreated in Gran Turismo 3: A-Spec under the name Tokyo Route 246. The same track is also featured in subsequent games in the series up until Gran Turismo 6. The Nogizaka46 song "Route 246" is named after the route.
