The debut of the Tobu Skytree Line 50050, which offers a direct connection through three of Japan's prefectures - from Kuki/Minami-Kurihashi in the nothern Saitama Prefecture to Chuo-Rinkan in the southern Kanagawa Prefecture, passing Tokyo.

The Tobu Model 50050, which is based on the Tojo Line Model 50000, was introduced in 2005 and functions as a direct train with 10 cars. Trains after Model 50061F are considered part of the late stage series, which is characterized by the lack of a forced ventilation system, and large single pane windows. In recent years, the headlights have been swapped to LED lights.
