En Iwamura's artistic exploration centres on transforming viewers' spatial experiences through site-responsive installations, drawing inspiration from the Japanese philosophy of "Ma." This philosophy, encompassing elements like distance, moments, and relationships, is a guiding principle in his work. Iwamura's installations allow viewers to engage with and discover their sense of "Ma" within the space.

In addition to installations, Iwamura creates ceramic characters infused with humour and serenity, inspired by the concept of "Ma”, which imbues tangible energy and emotions into his creations. These characters often feature repeated lines reminiscent of Zen Buddhist garden patterns.

He is an artist who enjoys exploring different styles and materials, such as ceramics. He likes experimenting with different colours and textures, sometimes mixing them by hand. He finds inspiration from various artists, including Ken Price, Katharina Fritsch, and Ugo Rondinone.

Iwamura sees ceramics as a universal cultural language, skillfully blending influences from Japanese traditional craft with a willingness to break conventions by infusing history with pop culture. He reimagines ceramics as a dynamic and evolving art form through his playful and skilful approach.
