Koyo Ibushi Jin is a large-format tile series handcrafted in Funatsu‑cho, Himeji by the master ceramicists at Koyo Seiga. Made using the traditional Ibushi Kawara method, each tile is formed from clay that is slowly fired and then smoked in a reduction chamber. This process creates a natural carbon layer that gives the surface its distinctive Ibushi Silver finish, a soft metallic sheen that responds subtly to light and continues to develop a refined patina over time. Koyo’s expertise in this technique has been trusted in the restoration of cultural landmarks, including the UNESCO-listed Himeji Castle.
Jin tiles are reversible, offering both a smooth and a finely ribbed face. This dual finish allows designers to alternate textures within a single layout, creating quiet variation through light and shadow. Mounted on mesh for efficient installation, Jin tiles bring structure, rhythm, and calm to both wall and floor applications.
Like all Koyo Ibushi products, Jin is made from clay and carbon only. There are no glazes, synthetic treatments, or chemical additives. Its microporous structure provides natural humidity regulation, odour absorption, UV and frost resistance, and far-infrared emission. These qualities are inherent in the material, making it both beautiful and functional.
Koyo Ibushi Jin is ideal for architectural environments that require discipline, tactility, and a material presence that matures over time. Whether used in minimalist interiors or outdoor surfaces, it brings together traditional craftsmanship and contemporary restraint with quiet authority.
Mittsu operates a structured supply model based on local stock, Japanese stock and samples.
Each route is designed to balance availability, cost and lead time depending on the nature of the project.
Local stock
Local stock represents a smaller portion of the overall range but accounts for the majority of supply by volume.

- Pallet delivery only to ensure safe transport
- Dispatch typically same or next working day
- Delivery usually within 3 to 10 days depending on location

Authentic Japanese ceramic tiles for architectural and interior design projects.
Mittsu specialises in tiles made in Japan, selected for their surface depth, natural glaze variation and architectural character.
Unlike mass-produced alternatives, these tiles are not defined by printed patterns. Their colour and texture are created during firing in the kiln, producing subtle variation across the surface once installed.
Choosing a tile
Japanese tiles are typically selected for their material quality rather than a fixed visual pattern.
Variation between tiles is part of the character. Across a wall, this creates depth and movement rather than repetition.
Collections can be explored online, but most projects benefit from reviewing physical samples before final selection.
Samples
Samples allow colour, glaze movement and surface texture to be evaluated under real lighting conditions.
They are ordered directly through product pages using the sample option for each tile.
For professional projects, the Specifier Program provides access to complimentary samples and technical resources.
Availability and supply
Tiles may be supplied from local stock in the UK, Europe or UAE, sourced from Japan, or produced to order depending on the collection and project requirements.
Lead times vary accordingly and should be considered during the design stage where tiles form part of the architectural concept.
Working with Mittsu
Mittsu works directly with architects, interior designers and private clients across residential, hospitality and commercial projects.
Each enquiry is handled with a focus on material selection, availability and suitability for the intended application.
Japanese tiles are specified as materials, not finishes.

Confirm colour, texture and glaze before specifying.
A sample is an appropriate representation of the tile and colour selected. Larger tiles have a single tile as a sample, smaller tiles have multiple. Samples are sent attached to a card, with the tile detail.
