BROOKLYN MUSEUM items are roughly selected from three types of leather.
Calf imported from Europe, daily steer imported from North America, and Wagyu leather.

A rare and high quality calf in the world.
In Europe, calfskin is supplied as a by-product from cultures such as French cuisine, and due to its quality, many big maisons are selected.
Therefore, it is hard to obtain leather due to the flood of market requests all over the world, but BROOKLYN MUSEUM enables stable procurement with the relationships cultivated over 40 years, and it has a great community formation with suppliers. It has become an asset.

Daily steer is a male cow.
Female dairy cows produce milk, so males are raised as meat. As the technology of artificial insemination has improved, castrated males have a very mild personality and are characterized by few scratches.
The difference between North American and Japanese hide is fiber.
In North America, people spend their time exploring the vast land, eating grain, so their fibers are soft and supple.
In Japan, it is carefully grown even in a limited land and eats grass, resulting in a firm, thin and delicate finish.

Creating things that can be passed on to the next generation.

Aiming for a "richer" expression that we draw, we carefully select the source of the raw leather, quality control, and dyeing method, and output it to the product.

Leather Working Group

An organization that clears environmental and social compliance with high standards and examines the impact on environmental protection and local conservation activities with international standards.

It is made up of brands, tanners, and drug makers related to leather, and has now been certified as a global standard with the luxury brand at the top.

565 companies

The number of tanners that have been certified by LWG worldwide. Among the tens of thousands of tanners, only those that have passed all the examinations such as energy and water usage, waste management, and scrutiny in the working environment can be obtained. Therefore, a rigorous examination is said to result in 90% failure in the first examination.

12.1 billion ℓ

The average amount of water that the world's tannars and manufacturers that are LWG certified reduce each year. About 23% of the world's leather production is LWG certified tanna. The amount of leather is about 3.9 billion ft2.. It is being reduced daily due to various capital investments and environmental considerations.

1 company

The only prosperous leather factory in Japan that has LWG certification. Until it was certified in 2018, we have provided sustainable leather after two years, such as replacing all equipment, replacing chemicals, and optimizing staffing by managing work process data.

Flourishing Leather Industry [Hyogo-Japan]

Obtained LWG certification for the first time in Japan in November 2018. It has been making leather consistently for more than 90 years since its establishment in 1928.
The entire production system has been established from raw leather procurement to finishing, and production recipes have been completely converted into data. 4-5 times a year, we invite engineers from home Italy to attract the finishes that match the world trends with Japanese skill.

Persimmon astringent dyeing

Tanner: flourishing leather industry

"Leather returning to the soil"

"Is it possible to finish leather with natural dyes?" Kakishibu dyeing, which started in 2003 with that in mind, was born in an era when mass production and consumption were flourishing all over the world.
As the harmful effects of air pollution and water pollution began to be shouted, I continued to ask what I could do as a leather industry.

"We should be able to make leather that can be used with more sympathy from natural materials that have no environmental impact."

The leather that has been completed through repeated trial manufacture with suppliers is . The pattern like wood grain is a hand-dyed brush eye.Above all, it is difficult to create this brush eye, and it is the only one in the industry.
However, the tanner who had been supporting us from the beginning did not work because of a lack of successors. BROOKLYN MUSEUM has picked up all the persimmon astringent dyed leather that was in the tanna, and managed to continue producing products so far.

"Kakishibu dyeing cannot be eliminated." Kakishibu dyeing has many fans not only in Japan but also overseas. I managed to find a tanner that can reproduce this brushed eye, but I'm relentlessly passing by.
At that time, I met the prosperous leather industry.

Leather-loving persimmon astringent dyes that have revived after trying many times, passionate about technology, and loving each other. Not only dyes, but also tanning and finishing can be returned to the soil by making things that do not rely on chemicals.

Craftsmanship and pride.
Leather that fascinates the world.

Tanner: Kaname [Tokyo-Japan]

"I want to stick to doing everything in Japan from the ranch to front tanning, rear tanning, dyeing, and finishing."
The person who fulfilled such a request was Kaname, who has long specialized in tanning tanning based on Nume leather.
Yamato, with its beautiful transparency, faithfully reproduces the custom color of BROOKLYN MUSEUM, so the finishing coloring is done by hand dyeing one by one. By this finish, deep aging is realized in the clear.
The high quality is recognized and Yamato items are selected for TOYOTA LEXUS lifestyle collection. I am traveling to the world.

Indigo dye

Dyeing: Aibuya [Tokushima-Japan]

Color that is colored by the balance of blue and purple.
Tokushima Prefecture's designated intangible cultural property "Awa Shoaizome Method". It wasn't the chemical dyes that we were particular about that "Japan Blue" that we met in the workshop that has been protecting traditional crafts as a cotton fabric weave since its founding in 1926. We have been discussing all the techniques of tanning, dyeing, squeezing, and finishing, which are completely different from the know-how of yarn dyeing, and finally indigo dyed leather is born.
Because it dyes leather only with the power to survive nature, it does not dye once. A vivid blue that emerges by spending time and effort looking at the "good mood" of indigo. And it's not just uniform, it's a natural beauty that makes you realize.
The good thing about indigo dyeing is not only the texture but also the sustainable dyeing method. It is natural that you can touch the dye with your bare hands. A craftsmanship-rich leather that has been close to the environment for hundreds of years.

Gross cordovan

Tanner: Shinki Leather [Himeji-Japan]
Radel Ogawa [Chiba-Japan]

Among the Code Van Tanners, which are said to be the only two in the world, we purchase raw leather from Japan's only Tanner , cut it, dye it and finish it to .
By soaking in plenty of oil from a general cordovan, you get a supple strength and firmness from the moment you pick it up. And the color creation of BROOKLYN MUSEUM is expressed by the tag with Radel Ogawa which is said to be the best dyeing technology.
It is a valuable leather that can be used for a lifetime as rare value increases worldwide and it becomes difficult to obtain high quality Cordova.

French calf

Tanner: Peringer [Germany]

BROOKLYN MUSEUM's French calf uses two types of leather according to the characteristics of the item.
Noblessa calf from Germany's prestigious tanner is used for leather accessories.
The birthplace of chrome tanning. Finished by a tanner with a history of more than 150 years in Germany and a number of achievements, a moderate firmness and beautiful shadows make the item elegant when it is picked up.
Of particular note is the richness of coloring. And the point that you can enjoy the color for many years. The firm calf is hard to lose its shape, and can be used for a soft texture. In addition, the finished embossing resists scratches and dirt and fits any lifestyle, so it is highly regarded by world-class luxury brands. We continue to polish top-class technology in terms of quality preservation and environmental consideration as well as the beauty of color development.

French calf

Tanner: Weinheimer [Germany]

BROOKLYN MUSEUM's French calf uses two types of leather according to the characteristics of the item.
The bag we use is a Wine Heimer word processor. Germany's world-famous tanner, and the tanner established by craftsmen in order to inherit traditional techniques from , which closed its history while being missed in recent years WEINHEIMER LEDER
The soft texture of the calf, with the moderate elasticity and fine elasticity of the fibrous material, and the polite finish of the tanna feels as an aura. I came to this leather in search of a body that touches the skin and fits flexibly.
Finish that is strong against scratches, dirt and water. Each time you pick it up, its stylish appearance will widen the range of coordination.
In Germany, which is an environmentally advanced country, the tanner has a clear traceability and faces leather at a higher standard. Feel the aesthetics of craftsmen recognized by the world.
