      在創作理念上，石山哲也關注「存在轉化」的過程，透過對各種角色的想像與詮釋，捕捉平凡形象瞬間轉變為「神」的片刻。他對於那些原本並非神祇的角色，如何在意識流轉中逐漸被賦予神性，產生濃厚興趣。藝術家以細膩且富有張力的造形，塑造出獨特而鮮明的神性形象，並藉由這些作品開啟對未知世界的探索。

Tetsuya Ishiyama was born in Saitama, Japan. He has undertaken artist residencies in Taiwan, Hong Kong, and China, building an extensive exhibition record and holding numerous solo exhibitions across Japan, Taiwan, and Hong Kong. He previously worked at the Shigaraki Ceramic Cultural Park, where he developed strong expertise in both artistic practice and kiln-firing techniques, demonstrating a high level of maturity and technical excellence. His work has received wide recognition, including the Shiga Prefecture Cultural Arts Encouragement Award and the Excellence Prize at the Taiwan International Ceramics Biennale. He holds a significant presence among mid-career artists in Japan and is also highly regarded in Taiwan, where he currently resides and continues his practice.

Conceptually, Ishiyama’s work centers on the process of “transformation of existence.” Through the imagination and reinterpretation of various figures, he captures the moment in which ordinary forms are transformed into icons—figures that embody an emergent sense of divinity. He is particularly interested in how beings that are not originally divine gradually acquire a sense of divinity through shifts in consciousness. With refined and dynamic sculptural forms, the artist creates distinctive and vividly characterized divine figures, using these works as a gateway to explore unknown realms and expand the imaginative possibilities between reality and the unseen.
