Background

What happened

Nishiyamato Academy of California has notified the California Attorney General that it became aware of unauthorized access to its computer network on or about March 27, 2026. According to the school, it secured its systems and engaged outside cybersecurity specialists to investigate. The investigation determined that an unauthorized party had access to the network between March 25 and March 28, 2026, and that certain files may have been accessed or acquired during that window.

The school completed its review of the affected files on September 1, 2026 and filed its notice with the California Attorney General on September 30, 2026. The public notice states that the files contained recipients' full names along with other personal information, but the sample letter does not itemize the additional data elements. Nishiyamato Academy is offering complimentary Kroll identity monitoring, including single bureau credit monitoring, fraud consultation, and identity theft restoration. About six months passed between the school's discovery of the incident in March 2026 and the September 2026 notice letters.

Schools often hold records about children as well as adults, including enrollment, family contact, and employment records. Because the public notice does not list the data categories involved, notice recipients should read their individual letter closely, and parents should consider whether a child's information may have been included.

What to do if you received a letter

1

Keep your notice letter

Do not discard it. Your letter contains the enrollment code for the Kroll identity monitoring and is important evidence if you decide to participate in a lawsuit. It is also the only document that lists the specific information involved for you, since the public filing does not.

2

Enroll in the free Kroll identity monitoring

Enroll in the Kroll identity monitoring offered in your letter at enroll.krollmonitoring.com before the activation deadline printed on it. The service includes single bureau credit monitoring, fraud consultation, and identity theft restoration. Accepting this benefit does not waive your right to pursue legal action.

3

Place a fraud alert or credit freeze

Contact Equifax, Experian, and TransUnion to place a fraud alert or freeze on your file. Request a free weekly credit report from AnnualCreditReport.com, and use the FTC's IdentityTheft.gov recovery guide. Also request your free annual credit reports at AnnualCreditReport.com and look for accounts or inquiries you do not recognize. If your child's information may be involved, consider asking the credit bureaus whether a credit file exists in the child's name and placing a freeze.

FAQ

Common questions

I received a data breach letter from Nishiyamato Academy. What should I do? +

Keep your notice letter, then activate the free Kroll identity monitoring using the instructions and activation code printed on it. Review your bank, credit card, and other financial statements for charges you do not recognize, pull your free credit reports at AnnualCreditReport.com, and consider a fraud alert or a credit freeze with Equifax, Experian, and TransUnion. Parents should also consider whether a child's information may be involved. If you see anything unfamiliar, document it, because out-of-pocket losses and time spent responding can matter in a class action.

Am I eligible to join a class action against Nishiyamato Academy? +

If you received a notice letter from Nishiyamato Academy, your information was in the affected files and you may qualify. Eligibility generally depends on your state of residence, the categories of information involved in your specific letter, and whether you can document losses or time spent responding. A free evaluation is the fastest way to find out where you stand.

How much money could I receive from a class action lawsuit? +

Data breach class action recoveries vary significantly. Settlements typically range from a few hundred dollars for basic out-of-pocket losses to several thousand dollars for documented identity theft, with class size, damages, and negotiation all affecting the final amount. No payout is guaranteed, and this investigation has not yet resulted in a settlement.

What personal information was exposed in the breach? +

Nishiyamato Academy's notice says the affected files contained recipients' full names and other personal information, but the sample letter filed with the California Attorney General does not list the additional data elements. Your individual letter is the document that identifies what applied to you, so read it closely and keep it. We do not assume more was exposed than the school has stated.

Did Nishiyamato Academy offer free credit monitoring? +

Yes. Nishiyamato Academy is offering complimentary identity monitoring through Kroll, covering single bureau credit monitoring, fraud consultation, and identity theft restoration. The public sample letter does not state the length of the service, so check your own letter for the duration and the activation deadline. Enrolling does not waive your right to pursue a claim.

How many people were affected by the Nishiyamato Academy breach? +

Nishiyamato Academy has not publicly disclosed the total number of individuals affected. The sample notice filed with the California Attorney General on September 30, 2026 does not include a count. This page will be updated if the school or a regulator releases that figure.

Is there a deadline to take legal action? +

Yes. Statutes of limitations for data breach claims vary by state and legal theory, typically ranging from one to six years. Waiting can permanently bar your claim. Contact us as soon as possible for a free evaluation.

How do I get a copy of the official breach notice? +

The sample notice is posted on the California Attorney General's data breach notification site, and it is linked in the Sources section of this page. If you cannot locate your copy or need help reading it, Dapeer Law can help you obtain and review it during a free consultation.
