[Kawaguchi Town Factory's Challenge] Introducing the 'Ginen Plate,' a 6mm Ultra-Thick Stainless Steel Plate that Overturns Conventional Heat Control Wisdom. Offering 'Permanent Re-polishing Refresh Service' as a Lifelong Partner.

Fujimura Seisakusho Co., Ltd., which has honed its precision sheet metal processing skills in Kawaguchi City, Saitama Prefecture for 25 years, will be pre-releasing the 'Ginen (Silver Flame) Plate,' a 6mm ultra-thick stainless steel griddle that redefines the norms of outdoor and home cooking, on Makuake starting April 30, 2026, under its original brand 'Digital Structure.' Luxuriously using high-grade SUS304 stainless steel, also used in food processing equipment, it achieves overwhelming toughness as a 'no-fuss griddle' that is rust-free, robust, and hygienic, allowing for knife use and metal scourer cleaning without hesitation. Furthermore, it offers a 'Permanent Re-polishing Refresh Service' where craftsmen inspect and re-polish each griddle, addressing scratches and dullness that occur with use. Leveraging the material characteristics of 6mm ultra-thick stainless steel, this service aims to restore the griddle to optimal practical condition without limitations on frequency or years of use. It's not disposable, but a tool that can be used for a long time with care. We deliver the value of a 'lifelong griddle' that will accompany you forever.

■ Why a stainless steel griddle now?

With the growing popularity of outdoor activities and the diversification of home cooking, cooking utensils are now required to have even greater 'hygiene,' 'durability,' and 'ease of handling.'
Traditional carbon steel griddles, while having the charm of 'developing character with use,' were prone to rust and required seasoning and careful storage.

This is where SUS304 stainless steel, also adopted for food processing equipment, is drawing attention.

Extremely resistant to rust, easy to use both outdoors and at home. Odor and dirt-resistant, highly hygienic. No seasoning required, easy to clean with a metal scourer. High strength, resistant to scratches even with a knife.

The strength of stainless steel griddles is to present a new standard of 'maintenance-free' x 'hygienic' x 'robust' in the outdoor domain, where 'seasoning griddles' were mainstream.

Even if burns or scratches occur with use, craftsmen will inspect the condition and re-polish it to prepare the surface for continued use. It is outdoor gear for a long relationship through care, not replacement.

■ Development Background: 25 years of technology into 'tools that connect with users'

Fujimura Seisakusho is a town factory that has honed its skills for 25 years in a world where even a 0.1mm deviation is unforgivable, producing industrial equipment and precision parts.

The 'Ginen Plate,' a 6mm ultra-thick stainless steel griddle, was born from the desire to elevate the processing technology cultivated over many years into 'a lifelong tool that remains in the user's hands.'

This product, where all cutting, chamfering, and polishing are meticulously finished by skilled craftsmen one by one, pursues a design that can be a long-term companion as a 'nurturing gear,' not a consumable.

Furthermore, the 'Ginen Plate' uses 6mm thick SUS304, which entails significant processing load and cost. However, this structure was chosen because it was 'inevitable for achieving the highest quality.'

A craftsman's belief that they wanted to create something they could proudly call the 'best griddle,' even if it meant disregarding the raw material cost, is condensed into this single griddle.

6mm ultra-thick stainless steel 'Ginen Plate' born from 25 years of precision sheet metal processing technology.

Uses 6mm thick SUS304 stainless steel.
Utilizing its thickness and material properties, it is an outdoor plate whose value accumulates with continued use.

■ Three innovations of the 'Ginen Plate'

① [Heat Battery] Overwhelming heat storage capacity created by 6mm ultra-thick SUS304

The Ginen Plate adopts a '6mm thickness,' thicker than general cooking plates. While stainless steel has low thermal conductivity, increasing its thickness enhances heat storage, making heat control easier to stabilize. The stable heat generated by its thickness beautifully finishes steaks with a perfect sear and fluffy pancakes. It's a griddle that can achieve 'next-level grilling' even outdoors.

Development secret story: Confirmation of the effectiveness of the 6mm heat storage structure through actual use verification.

Prototypes were provided to outdoor enthusiasts and cooking experts for verification in actual use environments.

During this process, interesting cases confirming the validity of the product specifications were identified.

One verifier reported that when cooking pancakes, 'it was easier to bake evenly even with residual heat.'

Pancakes are prone to burning and uneven cooking, and it is said that adjusting heat is difficult with general cooking utensils. However, the 6mm thick SUS304 plate adopted in this product significantly improves heat storage by compensating for the low thermal conductivity characteristic of stainless steel with its thickness. This result is an example demonstrating the effectiveness of the 6mm thick heat storage design.

Regarding this verification result, some collaborators gave feedback such as 'I felt high heat stability for home use,' which became a strong basis for the final decision to adopt the 6mm thick specification. Thick steaks also, with the 6mm heat storage, will be crispy on the outside and juicy on the inside.
