What is Takaoka Copperware? The 400-Year Craft Story of “Kanaya-machi”
“Takaoka Copperware,” passed down for over 400 years in Takaoka City, Toyama Prefecture, is one of Japan’s representative traditional crafts. Its origins date back to the early Edo period, beginning as an industrial promotion policy by the Kaga Domain.
Centered in Kanaya-machi, this region has adapted to changing times, creating products spanning from religious items like Buddhist altar fittings and bronze statues to contemporary art and interior design. Here, we’ll introduce the origins and development of Takaoka Copperware, along with its world-renowned craftsmanship and networks, from three perspectives.
Japan’s Premier Copperware Production Center Built by Kaga Domain Casting Artisans
The origins of Takaoka Copperware trace back to 1609, when Kaga Domain lord Maeda Toshimasa built Takaoka Castle and invited seven casting masters to what is now Kanaya-machi, establishing a foundry. This was implemented as an industrial promotion policy to support the castle town’s economy.
The invited craftsmen primarily cast daily necessities and farming tools like pots, kettles, and hoes. By the mid-Edo period, they expanded their product range to include Buddhist altar fittings, tea ceremony utensils, and artistic vases. Through this evolution, Takaoka developed into a nationally renowned casting town, continuously refining its techniques.
During the Meiji and Taisho periods, they incorporated Western-style sand casting, new coloring methods, and electric blowers, expanding into bronze statues and modern interior items. Today, Takaoka has become Japan’s largest casting production center, with over 90% of the domestic copperware market share.
Kanaya-machi preserves stone-paved streets and traditional latticed townhouses, designated as an Important Traditional Buildings Preservation District, carrying forward over 400 years of casting culture and craftsman pride.
From Buddhist Altar Fittings to Art Pieces – Evolving Design and Techniques
Takaoka Copperware has evolved its design and techniques to meet contemporary needs, extending beyond traditional products like Buddhist altar fittings and bronze statues. Recent years have seen active collaborations with domestic and international designers and brands, gaining attention in contemporary art, interior design, and lifestyle goods.
For example, the specialized coloring workshop “Momentum Factory Orii” developed copper panel “ORII MARBLE,” which won the 2017 Good Design Award for its minimal forms utilizing traditional coloring techniques.
Additionally, the brass and copper vessel brand “KISEN” continues exhibiting at European trade shows, promoting Takaoka Copperware’s aesthetic sensibilities to international markets.
Takaoka’s unique finishing techniques known as “iro-age” (chemical coloring) and “ihada-shiage” (cast surface finishing) bring out textures unique to handcraft, adding warm depth to contemporary products like vases and lighting. Local technical introduction websites also highlight the coloring process as a major attraction of Takaoka Copperware.
This advancement is realized through the fusion of long-cultivated casting and coloring techniques with fresh ideas from young craftsmen and creators. The appeal of Takaoka Copperware lies in its re-evaluation as items that harmonize with contemporary lifestyles while maintaining their traditional craft heritage.

Division of Labor and Craftsman Networks Supporting UNESCO Registration
The quality and diversity of Takaoka Copperware are supported by its “division of labor system” and “craftsman networks.” A single product involves over 10 processes including casting, polishing, metal engraving, coloring, and finishing, each handled by specialized craftsmen.
This sophisticated division of labor system enables the creation of complex, high-quality products impossible for a single craftsperson. The craftsmen are concentrated in the Takaoka region, collaborating through detailed communication to complete products, which is another distinctive feature.
This regional integrated craft culture supports the inheritance and development of techniques, leading to Takaoka City’s registration in UNESCO’s Creative Cities Network under “Crafts and Folk Arts” in 2017. Activities for nurturing young craftsmen, regional exhibitions, and open factory events continue actively, sustaining efforts that carry forward the future of Takaoka as a manufacturing city.
Deep Dive into Appeal! Three Reasons Why Takaoka Copperware is Loved Worldwide
Takaoka Copperware, boasting 400 years of tradition, is highly valued not only domestically but internationally. Its appeal extends beyond being merely “traditional craftsmanship” to encompass remarkably precise techniques, material characteristics that allow enjoyment of aging, and fusion with contemporary design.
Why is Takaoka Copperware attracting attention from users and artists worldwide today? Here, we’ll explore three perspectives on why Takaoka Copperware is loved globally.
1/100mm Precision Cast Surface Quality and Diverse Coloring Techniques
One of Takaoka Copperware’s greatest attractions lies in its precise casting technology and unique coloring methods. In the casting process, copper alloys are melted at approximately 1150-1250°C, and temperature control when pouring into molds is extremely critical. If the temperature is too high, the surface becomes rough, so craftsmen work with utmost care.
In finishing processes, techniques like polishing, metal engraving, and inlay (zogan) are employed, carefully finishing even the finest details. Particularly in coloring, techniques utilizing copper’s corrosive properties create colors and patterns through chemical reactions between chemicals, flames, and other natural elements with metal. This produces products with unique characteristics like verdigris green and red copper colors.
Durability × Aging Beauty – “Bronze Flavor” that Deepens with Use
Takaoka Copperware is characterized by durability and beauty through aging. Copper has excellent corrosion resistance and doesn’t easily corrode even when exposed to wind and rain, which is why many bronze bells and swords excavated from ancient ruins retain their original forms.
Similarly, Takaoka Copperware can maintain its beauty over long periods with proper maintenance. Additionally, unique characteristics develop on the surface over time, and the flavor deepens with use, which is another attraction. Due to these properties, Takaoka Copperware is also called “craft for appreciating patina,” becoming a reason for long-term cherishment.
Unique Designs Born from Collaborations with Contemporary Artists
While preserving traditional techniques, Takaoka Copperware actively collaborates with contemporary artists and designers to create new value. For example, Momentum Factory Orii develops products different from conventional crafts using unique coloring methods that evolved from traditional coloring techniques.
Additionally, Nagae Co., Ltd.’s art division develops products suited to contemporary lifestyles through designer collaborations. These initiatives have attracted international attention to Takaoka Copperware, expanding new possibilities for traditional crafts.
How to Choose Takaoka Copperware?
Takaoka Copperware receives high praise domestically and internationally for its quality and beauty. However, first-time buyers may wonder how to choose properly.
Here, we’ll explain in detail the key points for selecting Takaoka Copperware, including how to verify traditional marks and artist signatures, quality assessment checkpoints, and size and weight guidelines by intended use.
Verifying Traditional Marks “Takaoka Copperware Seals” and Artist Signatures
The first step in identifying authentic Takaoka Copperware is confirming the presence of the gold “traditional mark” certificate given to nationally designated “Traditional Crafts” and the regional certificate managed by the Takaoka Copperware Promotion Cooperative. The gold traditional mark is official endorsement affixed only to products meeting five conditions under the Traditional Crafts Act: daily use items, primarily handmade, techniques continuing over 100 years, among others. The certificate includes identification numbers enabling origin tracking.
The regional certificate is a sticker bearing “Takaoka Copperware” designation and cooperative seal, indicating that casting through finishing was performed within Takaoka City. The cooperative warns that products with only “Takaoka” characters carved on overseas castings are “not recognized as Takaoka Copperware,” and legitimate products always bear this certificate.
Next to note are artist signatures. Takaoka Copperware has a tradition of engraving artist names, workshop names, and production years on the bottom or sides of pieces. Signatures from Cultural Medal recipients and traditional craft masters particularly influence market value significantly. Having signatures also facilitates maintenance and appraisal history management, becoming elements that enhance future asset value.
Thus, by checking these three points: ①gold traditional mark, ②Takaoka Copperware regional certificate, ③engraved artist signatures, you can identify authentic Takaoka Copperware with high accuracy. When purchasing, don’t judge solely from online images; confirm close-up photos of certificates and signature locations, and contact the cooperative if you have questions.
Size and Weight Guidelines for Buddhist Altar Fittings, Tea Utensils, and Interior Items
While Takaoka Copperware varies greatly in size and weight depending on intended use, knowing rough guidelines is helpful when purchasing.
Buddhist Altar Fittings
Commercially available small Buddhist altar fittings like incense burners and candle holders are typically 6-10 cm in height and weigh 200-600g. For example, a 6.4 cm tall candlestick (2-sun size) is extra-small, weighing approximately 200g. Conversely, tall items like flower holders and bells can reach 18 cm in height and 1.6 kg in weight, requiring consideration of Buddhist altar size and stability. Therefore, the general guideline for Buddhist altar fittings is “height 5-18 cm, weight 200g-1.6 kg.”
Tea Utensils
Tea utensils are represented by teapots and tea caddies. For example, a copper side-handle teapot sold by Seigado at Mitsukoshi Isetan has approximately 350 mL capacity and weighs about 330g, making it a compact desktop size.
Additionally, FUTAGAMI’s brass “Susumu Tea Caddy (Medium)” measures 87mm diameter × 75.5mm height, weighs about 580g, and stores about 100g of sencha tea. Particularly in Takaoka Copperware, thick cast surfaces are retained to enhance heat retention, tending to be somewhat heavier than ceramic versions. The practical range is 100-350 mL capacity with 300-800g weight.
Interior Items
Interior ornaments and vases prioritize design, with vastly different sizes and weights. Desktop palm-sized vases are around 10 cm height and 300g weight, but large floor-standing bronze statues can weigh dozens of kilograms. Consider installation site load capacity and transport routes, checking not only dimensions but “whether it’s movable weight” and “shelf load capacity” for peace of mind.
