Shared Forges and Equipment Sharing in the Sword Industry: New Trends in Regional Swordsmith Collaboration

Structural Burden of Sword Makers' Independent Business Startup

Modern swordsmiths who wish to set up their own independent forges require initial investments of several million yen just for basic equipment such as furnaces, bellows, anvils, and various hammers. Moreover, considering the practical customary target for the number of swords made (approximately 24 per year according to guidance from the Agency for Cultural Affairs) and the costs of materials and utilities, independent management by young sword makers is extremely difficult. In rural areas, cases are mounting where disciples close their business immediately upon independence, which has become one cause of the succession problem.

The burden is not limited to equipment costs alone. Securing a location for the forge, considerations for fire prevention and soundproofing, and coordination with neighboring residents are among the hurdles besides financial matters that accompany independent startup. In urban areas, suitable properties for forges are scarce, and even in rural areas, many cases involve searching for suitable locations by converting vacant buildings or closed workshops. These non-financial burdens are also one factor making independent startup difficult.

Recently attracting attention as a means to overcome this situation are shared forges (kyōdōkajiba) and equipment sharing systems. This is a mechanism in which multiple sword makers share furnaces and large equipment, dividing usage fees to reduce individual fixed costs.

Precedent Cases of Shared Forges — Shimane, Fukuoka, and Gifu

Notable among precedent cases is the training forge attached to "Nittoho Tatara" in Shimane Prefecture. Here, young sword makers engage in sword making while sharing equipment for a certain period, sharing material costs and furnace maintenance expenses. It functions as "equipment use with apprenticeship" before independent startup, and is highly regarded as a regional sword maker support model.

In Fukuoka, a case has emerged where multiple young sword makers established a voluntary association and operate a shared forge in a renovated traditional house. Being a loose partnership without legal entity status, capital risk is low, and its characteristic feature is the flexible form where each maintains independent accounting while sharing only the facilities.

In Seki, Gifu, against the background of concentration of the cutlery industry, discussion is underway on setting up "cutlery hub" type facilities where sword makers and cutlery craftspeople share equipment within the same facility. Although swords and kitchen knives differ in forging temperature and finishing, there are not few common specifications between furnaces and blowers.

Common to all three cases is that rather than building shared forges from scratch, they are based on frameworks already existing in the region, such as existing training systems, industrial concentration, and voluntary associations. The concept of how to combine regional resources has become the common key to realizing shared forges.

Business Model Changes Brought by Equipment Sharing

The traditional sword maker business model was fundamentally a single path: "independence from the master's workshop → establishing one's own forge → nurturing successors through master-disciple relationships." Equipment sharing adds alternative options to this structure.

The specific economic benefits are as follows. A furnace's useful life can extend 20 to 30 years or more with proper management, but in sole ownership it is limited by the annual operating hours of a single sword maker. Sharing increases utilization rate and shortens the depreciation period for repair costs. The same applies to bellows and electric blowers.

However, challenges also exist. Clarifying operational rules is essential, such as adjusting usage times, managing furnace temperature history, and dividing the burden of consumables (bricks, refractory materials). Since sword makers are individual artisans, there is some psychological resistance to entering another person's forge.

Practical Points to Confirm Before Implementing Sharing

For sword makers considering participation in shared forges, there are many practical matters that should be agreed upon in advance. Representative items are listed below.

• Usage schedule management method: To avoid duplicate reservations, a mechanism to clearly specify who uses the furnace and when is needed.
• Standards for burden of consumables and repair costs: Prior agreement is required on whether replacement costs for bricks and refractory materials are divided according to usage frequency or divided equally.
• Scope of responsibility in case of accidents or damage: It is necessary to clearly define who bears responsibility and to what extent in case of unforeseen circumstances such as equipment damage or fire.
• Rules for withdrawal and new participation: How to recalculate equipment shares and burden amounts when membership changes should also be agreed upon.

These are points common to all mechanisms where multiple businesses share assets, not limited to shared forges, and documenting them rather than relying on verbal agreements is the basis for avoiding troubles.

Possibilities for Coordination with Local Governments and Subsidies

In recent years, there has been active movement to allocate subsidies for equipment setup of traditional crafts in the context of regional revitalization. There is increasing effort to attract public funds for shared forge development by utilizing the Agency for Cultural Affairs' "Cultural Arts Promotion Subsidy" and various prefectural industrial support subsidies.

Importantly, by applying in the form of "subsidies to joint facilities development and operating organizations" rather than "subsidies to individual sword makers," it becomes easier for multiple sword makers to be recognized as beneficiaries. A comprehensive application scheme involving both the cultural heritage division and the industrial promotion division of local governments is considered effective.

In utilizing subsidies, it is practically important to clarify in advance how eligible expenses are categorized (whether they fall under equipment costs, renovation costs, or operational costs) and to keep expense records in preparation for performance reports after application. Such administrative work, which tends to be time-consuming for individual sword makers, becomes easier to share when the operating organization centralizes the contact point.

Limits of Sharing and Respect for Individual Craftsmanship

However, Japanese swords are founded on the cultural premise that "one sword maker bears responsibility for one blade." Even if multiple sword makers use the same furnace in a shared forge, each remains an independent sword-making entity. The signature is cut by an individual, and the responsibility for creation cannot be divided.

Equipment sharing is limited to "sharing the space and equipment" and is not "sharing the creation process." Maintaining this distinction clearly is essential to ensure the credibility and legal validity of the sharing arrangement.

This point is the same in the context of appraisal. Even for swords made in shared forges, appraisal and issuance of appraisal certificates are done for individual works, and whether equipment is shared does not affect the evaluation of the works themselves. Sharing is merely a rationalization of the production environment and exists in a separate dimension from the value of works or individual skill.

Industry Adoption Issues and Future Outlook

At present, cases of shared forges are still few in number, and institutional adoption requires involvement of industry organizations (such as the All Japan Sword Preservation Society and the Japan Art Sword Preservation Association). The next step would be to share model cases across the entire industry and establish guidelines and standard contract formats regarding equipment sharing.

In the digitalized present day, shared forges equipped with cloud-based equipment reservation management systems have begun to appear experimentally. There are also efforts to record and share furnace temperature history using IoT sensors, and technological advancement has the potential to support institutional sharing.

In parallel with such technical improvements, operational coordination is also essential, such as how much information participating sword makers share with each other and at what frequency operations are reviewed. Only when both the institutional and technological wheels are in place can shared forges function not as temporary support measures but as sustainable business foundations.

How to balance the individuality of sword makers with rational equipment sharing — this question has become a critical point determining the sustainable future of the Japanese sword industry.
