Hirosue High (広末 Hirosue) is the high school Senku, Taiju and Yuzuriha attended prior to petrification. The Camphor Tree is in the courtyard.



  • The school's name is composed of the kanji for "big, vast" (広) and "trunk/leaves of a tree" (末), probably a nod to the camphor tree that grows on the grounds.
    • Had Taiju graduated from the school, his diploma would have read "big-tree big-tree from big-tree high school".
  • The high school's name was only revealed in Chapter 157, page 4.
