This is a manhole photo in Otawara I posted this last year but I wanted to post it again since I found who I believe the samurai is. I believe this is Nasu no Yoichi. There is a statue in Otawara that also is Nasu no Yoichi so he must be a symbol of the city.
Nasu no Yoichi (那須 与一?) (c. 1169 – c. 1232) was a samurai who fought alongside the Minamoto clan in the Genpei War. He is particularly famous for his actions at the Battle of Yashima in 1184. According to the Heike Monogatari, the enemy Taira placed a fan atop the mast of one of their ships, claiming it protected the ship from arrows, and daring the Minamoto warriors to shoot it off. Sitting atop his mount in the waves, his target atop the ship rocking as well, Nasu nevertheless shot it down with only one shot. (Wikipedia)
