Nitori says personal data of up to 37.62 million records may have leaked

Nitori Holdings, Japan's big furniture and home goods retailer, has confirmed that someone got into its systems from the outside. On November 9, the company announced that up to 37.62 million personal data records may have been leaked.

The data that may be affected includes member information for both individual and corporate customers. Nitori says the figure is a maximum, and it describes the leak as a possibility, not a confirmed loss of every record.

That is a huge number in a country of about 125 million people. If you have ever signed up as a Nitori member, this one is worth following.

Not the first big hit

Japanese companies have had a rough year online. In September 2025, Asahi Group was hit by ransomware that disrupted its ordering and shipping. In October 2025, the same kind of attack on office supplies retailer Askul halted orders for Muji and Loft online shops.
