Yubinohara (夕日野原?) is a location appearing in the Guardian Angels Of The Sky series. Yubinohara is the main location of Guardian Angel Of The Sky: Legend of the Rainbow. Yubinohara is the name of Hisakata before it was changed in the 19th century. Yubinohara is also the place where the Yuujo Castle can be found.
The place's name comes from Yubi (夕日?), also spelled as "Yuuhi", meaning "evening sun", No (野?) meaning "field" and Hara (原?) also meaning "field". 野 and 原 and be fused and it still means "field". So Yubinohara means "place of the evening sun's field". By younger residents, Yubinohara is sometimes referred as "Yubino".
