The Shimōsa (しもうさ) is an all-stations train service in Japan operated by the East Japan Railway Company (JR East) between Kaihimmakuhari in the Chiba Prefecture and Ōmiya in theSaitama Prefecture.^[1] The Shimosa looks like the Musashino train because they use the same train stock. However, there are some differences between these two services, the Musashino train goes from Hachioji or Fuchu-hommachi whereas the Shimosa goes from Shin-Narashino or Kaihimmakuhari.

Three services operate every day, during the morning and evening rush hours. In the morning, 1 train originates from Shin-Narashino to Ōmiya, then returning to Kaihimmakuhari. In the evening, 2 trains originate from Shin-Narashino to Ōmiya, return to Nishi-Funabashi, then head back to Ōmiya again, before returning to Shin-Narashino. The timetables for weekdays and weekends are different. As a side note, the morning return train operates a one-stop service after it returns to Kaihimmakuhari, from Kaihimmakuhari to Shin-Narashino.^{[citation needed]}

The trains to and from Ōmiya use one of the Musashino Line freight branches, which connects the Musashino Line (Musashi-Urawa Station) and the Tōhoku Main Line (Yono Station).^[2] It also use parts of the Keiyo Line, from Minami-Funabashi to Kaihimmakuhari.
