Hidden within the grounds of a serene temple in Hiroshima Prefecture lies a breathtaking white marble paradise that looks like something from another world. Welcome to Miraishin no Oka (未来心の丘), or “Hill of Hope,” a unique open-air art space where spirituality and sculpture meet.
A Work of Art in a Temple Setting
Unlike many art installations, Miraishin no Oka is located inside the grounds of Kōsanji Temple (耕三寺), a historic and visually striking temple in Ikuchijima Island, part of the Seto Inland Sea. The location itself adds a spiritual and peaceful atmosphere to the experience.

This hilltop art space was created by world-renowned Japanese sculptor Itto Kuetani (杭谷一東). The entire site is made of pure white marble imported from Carrara, Italy, the same marble used by Michelangelo. The contrast between the marble’s crisp white and the blue sea and sky of Setouchi is absolutely stunning.
What to See
Miraishin no Oka spans 5,000 square meters, filled with abstract sculptures, stairways, arches, and platforms—all inviting visitors to explore and interact. Highlights include:
- “Tower of Light”, a symbolic sculpture standing proudly in the center of the site.
- Panoramic Views of the Seto Inland Sea and surrounding islands—perfect for photos.
- The marble itself, which changes color subtly with the sunlight, creating a dynamic visual experience.
This place is a fusion of Italian material, Japanese artistry, and spiritual expression. It’s also highly Instagrammable, especially during golden hour.
