About Nishiyamato Academy
Nishiyamato Academy of California is a private Japanese international day school serving students from pre-kindergarten through 9th grade in the Los Angeles metropolitan area. Founded in 1992 and located in Lomita, California, the school offers a bilingual Japanese-English curriculum recognized by Japan’s Ministry of Education and enrolls approximately 150 students. It is a sister school of Nishiyamato Gakuen in Nara Prefecture, Japan, and also operates a Saturday school program for children of Japanese expatriates.
What Happened?
Nishiyamato Academy was listed in a California Attorney General sample breach notice filed on September 30th, 2026. According to that filing, the school discovered unauthorized access to its computer network on or about March 27th, 2026. Working with external cybersecurity professionals, the school investigated the incident, and on September 1st, 2026, the investigation concluded that between March 25th, 2026 and March 28th, 2026, certain files containing personally identifiable information may have been subject to unauthorized access or acquisition. The notice confirms that full names were potentially exposed, along with additional data elements that were not publicly specified in the available notice text due to template placeholders. Kroll was engaged to provide complimentary identity monitoring services to affected individuals, though the duration of coverage and the enrollment deadline were also listed as template placeholders in the publicly available version of the notice.
The roughly six-month gap between the school’s discovery of the incident on March 27th, 2026 and the filing of consumer notifications on September 30th, 2026 is notable. No ransomware group claims, threat-actor attribution, prior breach history, or litigation related to this incident were found.

For stronger protection, a credit freeze with each bureau prevents new credit from being opened in your name entirely.
