Exhibiting at the 23rd Information Security Expo [Spring] (April 8-10, 2026, Tokyo Big Sight). April 6, 2026, Japan - Nitto Horukamu Co., Ltd. (Representatives: Masuo Karakama, Orio Karakama) announces that it holds numerous patents and utility models related to data destruction services that issue physical destruction certificates for various storage devices, including HDDs and SSDs.
Over the years, our company has thoroughly pursued the 'completeness,' 'provability,' and 'reproducibility' of data destruction, developing unique technologies that scientifically guarantee zero residual data after physical destruction. These technologies have already been patented and registered as utility models, and can be utilized by domestic IT Asset Disposition (ITAD) and IT Lifecycle Management (LCM) operators as a decisive platform for reliability and differentiation.
Specific Technical Details of Major Patents and Utility Models:
Our intellectual property portfolio consists of both hardware technology for physical destruction devices and software systems for operational management and certificate issuance, designed to be easily integrated into the services of ITAD/LCM operators.
- Patent No. 6734498 (Management method for information recording media destruction devices)
International patents (including Taiwan) acquired.
Specific content: A destruction device operation management system utilizing smartphones and management terminals. During the destruction work, it automatically acquires and transmits to a server the operator's personal identification information, destruction device identification information, GPS location information, work date and time, and image/video logs before and after destruction. By centrally managing this, it records 'when, where, who, what, and how' the destruction occurred with tamper-proofing (time-stamping and hashing). It significantly reduces the risk of fake destruction reports or media theft, realizing court-admissible traceability. Complies with the 5W2H2C high-risk approach framework.
- Utility Model Registration No. 3237647 (Adapter for information recording media destruction device)
Right holder: Masuo Karakama (Registered in 2022).
Specific content: Media fixing adapter compatible with the CrushBox series. With a V-groove and fixing pin structure, it stably secures various media such as HDDs/SSDs, enabling efficient and uniform crushing (punch & bend & waffle method). Meets physical destruction standards compliant with NSA/NIST.
- Utility Model Registration No. 3244870 (Adapter for information recording media destruction device)
Right holder: Masuo Karakama (Registered in 2023).
Specific content: Improved adapter specializing in SSD/LTO. Equipped with a precision adjustment mechanism, it supports crushing under 2mm square (cluster destruction) according to NSA standards. Also realizes the Japanese method of destruction that reduces environmental load while keeping the original shape.
