Introducing the Kaji Border tile, a remarkable creation crafted by one of Mittsu’s master ceramicists using traditional Japanese techniques. Each porcelain tile showcases the beauty of fine craftsmanship, offering a truly artisanal product. The deep, rich tones of the Koyohen tile, combined with its naturally occurring glaze variations, make it an exceptional choice for those seeking a blend of heritage and sophistication.

What sets the Kaji Border tile apart is its distinct glaze finish, which offers a mesmerising interplay of light and shadow. The glaze is carefully applied to create a dynamic, almost tactile surface that reflects its natural surroundings, enhancing the depth of each tile. This subtle texture gives the tile a multi-dimensional quality, making it not only visually appealing but also stimulating to the touch. The glaze’s variations in tone and finish, ensure that no two tiles are the same, adding a layer of uniqueness to any space.

Kaji Border features an intriguing and sympathetic aesthetic that’s rooted in its earthy, natural palette. Its slightly uneven texture evokes the feel of handcrafted pottery, while maintaining the durability and precision of modern ceramic work. This versatile tile is equally at home on walls or floors, providing an elegant yet timeless touch to both residential and commercial projects. Whether you’re seeking to add texture to a bathroom or bring an artistic element to a kitchen, Kaji Border is designed to enhance any space with its authentic craftsmanship, rich textures, and subtle beauty.

Specification

Specifying Japanese tiles requires a different approach to standard ceramic products.

Mittsu works closely with architects, interior designers and developers to support the specification of authentic Japanese tiles in architectural projects.

These tiles are produced by specialist manufacturers in Japan, often in regions such as Tajimi in Gifu Prefecture, part of the historic Mino ceramics area.

Many of these manufacturers are highly specialised and focused on the domestic market. Mittsu works directly with them and manages the complexity of sourcing, production and logistics.

Selecting tiles

Japanese tiles are selected for their glaze, texture and proportion rather than a fixed pattern.

The surface is created during firing in the kiln. Colour and variation are not printed onto the tile.

This produces natural differences in tone and glaze movement across each tile, creating a surface that behaves like a material once installed.

For this reason, Japanese tiles are often specified based on how they perform across a wall rather than how a single tile appears.

Samples

Most designers review physical samples before final selection.

Samples allow evaluation of colour variation, glaze movement, texture and reflectivity under real lighting conditions.

  • colour variation
  • glaze movement
  • surface texture
  • joint and proportion

Samples are ordered through the website using the sample links on each product page.

Professional project resources can also be accessed through the Specifier Resources page.

Technical information

Each product page includes key specification data required for project work.

  • tile dimensions
  • sheet size where applicable
  • thickness
  • material type
  • application suitability

CAD drawings are available for selected collections, with additional technical guidance provided where required.

Additional technical documents, CAD files and specification resources are available through the Mittsu Specifier Resources page.

Project advice

Mittsu supports architects and designers during the selection stage.

This typically includes guidance on layout, proportions, joint sizes and suitability for the intended application.

Early discussion often helps identify the most appropriate tiles before finalising the specification.

Budget and supply planning

Japanese tiles are produced in specialist kilns and positioned as a premium architectural material.

Aligning budget and design intent early in the project helps ensure the selected tile remains part of the final specification.

Tiles may be supplied from stock in the UK, Europe or UAE, directly from Japan, or produced to order.

Lead times vary depending on availability and production requirements, so early planning is recommended.

Procurement

Procurement is structured to suit the project.

Tiles can be invoiced to the architect, contractor or client, depending on how the project is organised.

Delivery can be arranged directly to site or through the project team.

Mittsu manages international logistics to ensure materials arrive safely and in sequence for installation.

Specification integrity

Kiln-fired Japanese tiles form part of the architectural design of a project.

Substituting alternative materials will change the visual outcome and compromise the intended design.

Japanese tiles should be specified early and considered as a material, not a finish.

Early coordination of samples, budget and lead time ensures the material remains consistent from concept through to installation.

Superclean Grout is an Anti-Mould Grout from master ceramicists, INAX of Japan.

This grout has been developed to exceed the exacting demands for cleanliness and hygiene of the Japanese people.

Moisture and dirt penetrate into conventional cement grout, causing mould growth on the surface. Superclean Grout transforms the property of grout particles to hydrophobic, dramatically reducing the penetration of moisture into the grout and preventing the grout from holding dirt and growing mould.

It's one of the few available in Europe that passes the high standard of Anti-Stain, Anti-Bacterial and Anti-Fungal of ISO Standard - ISO22196. 

Shipping

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.

Mittsu Japanese Tiles

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.
