We have already met Nichiren in my article NAM MYOHO RENGE KYO dealing with Lotus Sutra – Hoke-kyo. We have also visited the holliest site in the Nichiren Buddhist tradition – Ryuukou-ji in Enoshima in my article RYUUKOU-JI AND ST. NICHIREN.
St. Nichiren (1222-1282) was the founding priest of the temple we are about to visit now.
