What is "ryuko-ji"

is a temple of the Nichiren Shū in the city of Fujisawa, Kanagawa Prefecture, Japan. It stands on the site of the former Tatsukuchi (or Tatsunokuchi) Execution Grounds, and its name uses the same two kanji meaning "dragon mouth".

Major buildings at the temple include the Hondō, a five-story pagoda, a stupa (sharitō), and the Shichimendō. The cave where Nichiren was confined is preserved on the grounds. A statue of him stands in the courtyard in front of the Hondō.
