Overview
Oxide Corporation (株式会社オキサイド) is a Japanese research-and-development-driven company headquartered in Hokuto, Yamanashi Prefecture. Founded in October 2000 by Yasunori Furukawa, it was established as the first case under Japan's national civil servant dual-employment system, with Furukawa later leaving the National Institute for Materials Science (NIMS) in October 2003 to focus fully on running the company. Its mission is expressed as realizing a prosperous future through light technology. The company is built on proprietary crystal growth technology and optical wavelength-conversion technology. Its product portfolio spans single crystals, lasers, optical devices, optical modules, prototyping and services, and crystals for power semiconductors such as SiC. Early on it succeeded in developing Super LN/LT new products, described as a world first, and began selling them at international exhibitions in 2001. It subsequently expanded into optical devices (2005), optical modules (2006), DUV lasers (2010), and vacuum ultraviolet lasers (2018). Oxide serves the semiconductor, medical, and energy fields, aiming to be a globally leading company with a constant presence in optics. It has received numerous awards, including the Global Niche Top 100 selection by Japan's Ministry of Economy, Trade and Industry in 2014, and a Grand Prix at the Forbes JAPAN SMALL GIANTS AWARD in 2021. It has formed capital and business alliances with companies such as Toshiba Ceramics (now CoorsTek), Nikon, KLA-Tencor (now KLA Corporation), NTT Advanced Technology, and Lasertec. Oxide listed on the Tokyo Stock Exchange Mothers Market in April 2021 and moved to the TSE Growth Market in April 2022. It has expanded its manufacturing footprint in Hokuto with multiple factories and established Oxide Power Crystal Corporation in October 2024 as a consolidated subsidiary. The company continues to pursue growth in markets related to quantum computers and AI data centers, as highlighted in a 2026 Forbes JAPAN feature.
History
Oxide Corporation was founded in October 2000 by Yasunori Furukawa, who became the first person to establish a company under Japan's national civil servant dual-employment system. In October 2003, Furukawa retired from the National Institute for Materials Science (NIMS) to devote himself fully to the company. In May 2001, the company succeeded in developing Super LN/LT new products, described as a world first, and began selling them at international exhibitions. It received the 14th Small and Medium Enterprise Agency Director-General's Award in April 2002 and the 32nd Japanese Association for Crystal Growth Technology Award in July 2003.

In March 2014 it was selected for the Ministry of Economy, Trade and Industry's 'Global Niche Top 100'. In March 2015 it acquired the scintillator single crystal business from Hitachi Chemical (now Resonac). In April 2015 Dr.SPECKLE received the Laser Society of Japan Industry Contribution Award. In July 2015 a third factory was completed in Hokuto City, and in December 2015 a symposium commemorating the 15th anniversary was held. In January 2016 Dr.SPECKLE received the Japan Machinery Federation Chairman's Award. In April 2018 a deep ultraviolet solid-state continuous-wave laser received the Laser Society of Japan Industry Excellence Award, and in August 2018 the vacuum ultraviolet laser business began. In February 2021, the company won the Grand Prix at the Forbes JAPAN SMALL GIANTS AWARD. In April 2021 it listed on the Tokyo Stock Exchange Mothers Market. In October 2021 it formed a capital and business alliance with UJ-Crystal Corporation.
