Emperor Go-Fukakusa (後深草天皇, Go-Fukakusa-tennō, 28 June 1243 – 17 August 1304) was the 89th emperor of Japan, according to the traditional order of succession. This reign spanned the years 1246 through 1260. This 13th-century sovereign was named after the 9th-century Emperor Ninmyō and go- (後), translates literally as "later", and thus he could be called the "Later Emperor Fukakusa". The Japanese word go has also been translated to mean the "second one"; and in some older sources, this emperor may be identified as "Fukakusa, the second", or as "Fukakusa II".
