10/20/2025, 9:32:56 PM
Overview of the Incident
A significant cyberattack on Askul Corp., a Japanese office supplies retailer, has led to widespread disruptions in e-commerce operations for several major retailers, including Ryohin Keikaku Co., the parent company of the Muji brand, and The Loft Co. This ransomware attack, confirmed on October 20, 2025, has forced Askul to suspend online orders and product shipments across its platforms, including Askul, Lohaco, and Soloel Arena.
Impact on Retailers
Following the attack, Ryohin Keikaku announced the suspension of its Muji e-commerce site, effective from 9 p.m. on the same day. The Loft Co. also reported similar disruptions, halting its online sales due to logistics issues stemming from the attack. Both companies have indicated that their physical store operations remain unaffected, but the timeline for resuming online sales is currently undetermined.
The attack has raised concerns regarding the vulnerability of Japan's e-commerce infrastructure, particularly as this incident follows a recent cyberattack on Asahi Group, Japan's largest brewer, which disrupted its production and shipment processes. Analysts suggest that the cumulative impact of these incidents could lead to a loss of consumer confidence in online shopping.
Official Responses
Askul has publicly apologized for the inconvenience caused to its customers and stakeholders, stating that it is actively investigating the extent of the breach and working to restore its systems. The company is also assessing whether any personal or client data has been compromised. Ryohin Keikaku has downplayed the impact on its overall operations, noting that its e-commerce exposure is relatively low.
Criticism & Opposition
Critics have voiced concerns over the preparedness of Japanese retailers to handle cyber threats, especially given the recurrence of such incidents within a short timeframe. The reliance on shared logistics and e-commerce platforms among retailers has been highlighted as a potential risk factor that could exacerbate the effects of future cyberattacks.
