Princess Junshi (ç£åÂÂå 親çÂÂ; 1311 â 11 June 1337), or Shin-Muromachi-in (æ°室çºé¢), was a Japanese princess and an empress consort (Chà «gà «) of Emperor Go-Daigo of Japan.
She was a daughter of Emperor Go-Fushimi and the Court Lady Saionji (Fujiwara) Neishi. She was a younger sister of Emperor Kà Âgon, who was a member of the Jimyà Âin family line. For a period of time in the 13th and 14th centuries, the imperial line of succession would "swap" between two family lines: the Jimyà Âin and the Daikakuji. A Jimyà Âin emperor would be followed by a Daikakuji emperor, and so on.
In 1318, Go-Daigo, of the Daikakuji line, became emperor. In 1331, during the Genkà  incident, his plot to overthrow the Kamakura shogun was discovered, and the shogun responded by removing him from the throne, replacing him with Emperor Kà Âgon of the Jimyà Âin.
In 1333, after much conflict, Go-Daigo re-took the throne. As part of his plan to neutralize the potential power of Kà Âgon and the Jimyà Âin family, Go-Daigo married Junshi - Kà Âgon's sister.
Later on, she became known as Empress Dowager Shin-Muromachi-in.
