Founded in 1593 by the powerful samurai warlord Toyotomi Hideyoshi, Kongōbu-ji was established as a spiritual monument dedicated to immortalising his mother. This temple’s creation was more than just an act of filial piety, it became a lasting symbol of religious devotion and architectural mastery. Nestled in Koyasan, Kongōbu-ji quickly rose to prominence as a central hub for Shingon Buddhism, intertwining Hideyoshi’s legacy with the sacred landscape of Japan.

Mount Kōya, or Kōyasan, was first settled in 819AD by the legendary monk Kūkai, also known as Kōbō Daishi, who introduced esoteric Shingon Buddhism to Japan after studying in China.

It was established in 1984, some 1150 years after the death of Grand Master Kobo Daishi, as a place of calm contemplation.

With over 200,000 tombstones snaking through nearly two kilometre’s of the sacred Wakayama mountain forest, the Okunoin cemetery is the epicentre of ancient Shingon Buddhism and the mausoleum site for one of the most revered men in the religious history of Japan. Tucked away in the shadowy heart of Mount Kōya, Japan’s holiest mountain, Okunoin isn’t just Japan’s largest cemetery it’s a spiritual artery that pulses with esoteric energy, ancient Buddhist tradition and a deeply
