A project to deliver Sadako's origami cranes to people around the world, donated to the leaders of the G7 summit countries, Pope Francis, and former President Obama.

キャステム キャステム
Castem manufactures and sells Sadako Sasaki's origami crane "SADAKO," recreated in metal by combining precision casting technology with the latest digital technology. The initiative was prompted by the challenge of preserving and inheriting the origami cranes of Sadako, who lost her life due to the atomic bomb dropped on Hiroshima. Currently, there are about 100 origami cranes remaining with the Sasaki family and the Hiroshima Peace Memorial Museum. Although there have been requests for donations from both domestic and international sources, the number is limited, and it is not possible to meet all requests. Being made of paper, the cranes deteriorate over time, and proper preservation requires specialized knowledge and expensive equipment. To address these challenges, Castem utilized 3D scanning and precision casting technology to accurately recreate Sadako's origami cranes. The stainless steel SADAKO, faithfully reproducing the texture of the paper and the creases, can be preserved permanently and conveys a message of peace to the world. SADAKO was presented to the leaders of various countries at the G7 Hiroshima Summit in 2023, and it will be gifted to Pope Francis in 2024 and former President Obama in 2025, playing a role in spreading the wish for peace worldwide. Castem believes in the symbolic power of this story and the origami crane, and aims to contribute to peace by continuing to promote the project of delivering SADAKO to people around the world.

A trial version of the "Blink Detection Technology" app (browser version) is now available for free, and online sales of the Windows app for research and verification have also begun.

  • NEW
  • PRODUCT

We have released a "trial version app (browser version)" that allows you to freely test the "blinking detection technology" developed using joint patent technology with Panasonic, directly in your browser. No application, installation, or membership registration is required. It measures blinking for 30 seconds using your PC's built-in camera or your smartphone's camera, displaying the number of blinks, the rate per minute, the duration of closed eyes (average and longest), and the intervals between blinks in real-time. The camera footage is processed within the browser, and neither the video nor the measurement results are sent externally. Additionally, we have started online sales of the "blinking detection app (Windows version)" that allows unlimited measurements for research and verification purposes. It supports recording and CSV output, with prices set at 33,000 yen for general users and 16,500 yen for academic institutions (tax included, per license, one-time purchase). The camera input version and the file input version are sold separately. For integration into products and services, we also offer the "blinking detection SDK" (with a one-month free trial version available).

Started providing "Specific Voice Detection Edge AI System" using AI voice analysis.

  • NEW
  • PRODUCT

We will begin providing a new solution for construction companies, the "Specific Voice Detection Edge AI System," utilizing the development and operational insights from the "Specific Vehicle Detection System" co-developed with Toda Corporation, starting in September 2026. This system applies the technology of the productivity-enhancing AI camera "PROLICA" to pre-learn and analyze specific voice data collected by outdoor microphones, allowing AI to detect target sounds in real-time on-site. By using voice detection, it will be possible to early detect the presence of approaching emergency vehicles even in environments where traditional visual checks or image analysis by AI cameras are difficult due to obstructions like buildings or curves. By linking with various devices and automating the control of construction vehicle departures and alerts to workers, it contributes to improving safety at construction sites and surrounding roads. ■ Main Features of This System 1. High-precision detection using voice AI 2. Safety management independent of visibility 3. Real-time processing with edge AI For more details, please check the linked page.
