Diatec Co., Ltd., the Japanese manufacturer behind the FILCO mechanical keyboard brand, has ceased operations as of April 22, 2026. The company issued a notice on its website thanking customers for their support and announcing the sudden closure. Known for producing quality mechanical keyboards, Diatec's exit marks another shift in the competitive peripheral market.

FILCO gained recognition among keyboard enthusiasts for its Majestouch series, featuring robust casings and premium build quality. Their 2022 Majestouch Convertible3 supported both wired and wireless connections with multiple switch options. The 2023 Majestouch Xacro M10SP showcased innovation with its split design and 10 macro keys, appealing to ergonomic-focused users.

The company confirmed all personal data collected from customers was securely deleted by the closure date. Diatec's departure leaves a void in the premium mechanical keyboard segment, particularly for users who valued their no-frills, high-quality approach. The closure follows broader industry consolidation as keyboard manufacturing becomes increasingly competitive.
