Based in Paris, Galerie Guillaume Castellano specialises in Japanese art, with a particular focus on Buddhist sculpture, antique objects, and modern painting.

Maintaining close ties with Japan for over a decade, the gallery travels there regularly to source new works. Each piece is selected for its aesthetic quality, rarity, and historical significance.

The gallery’s selection highlights both the timeless elegance of classical arts and the expressive power of modern Japanese artists.

The gallery supports private collectors, enthusiasts, and institutions in building refined, high-quality collections.
