When I started the Japanese Grimoire Society, I had one goal: to build a place where the real tradition behind the anime — behind Kuji Kiri, behind Shingon Reiki — finally has a home. Not a wellness app. Not a beginner's course. A real grimoire. The kind that takes years to write. What is already inside: Deep texts on Shinto, Shingon and Shugendo. The real history behind Kuji Kiri. Reiki decoded from Japanese original sources — not the simplified Western version. Spirits, Buddhas, the tradition behind what you have seen in Naruto, Jujutsu Kaisen and Demon Slayer. Some doors are open. Some are still being carved. What is growing — week by week: 🎌 Start Here ⛩️ Shinto · Shingon · Shugendo 📜 The Open Grimoire 🌿 Foundations of Practice 🔮 Kuji Kiri Decoded ☀️ Shingon Reiki Decoded ⚔️ The Warrior's Path Decoded 🔮 Kuji Kiri Levels 1–3 🪷 Shingon Reiki Level 1 🐉 The Warrior's Path 🌙 Live Session Recordings 🖐️ The First Touch 🌬️ The First Step Not all of it is there yet. But it is coming — and it is going to be extraordinary. You are in the right place at exactly the right time. 🐉 Dr. Mark Hosak · PhD Japanese Studies, Heidelberg · Shingon lay monk · Founder of Shingon Reiki
