A May 2025 survey by Teikoku Databank found that around a third of Japanese companies had experienced a cyberattack. The online survey was aimed at 26,389 companies nationwide, receiving 10,645 valid responses.

A total of 32.0% of companies said that they had experienced a cyberattack, while 52.4% said that they had not and 15.6% said that they did not know. Large companies were more likely to have experienced such an attack at 41.9%, compared with 30.3% for small and medium-sized companies and 28.1% for small businesses alone.

Overall, 6.7% of companies experienced a cyberattack in the past month, but for this time period it was more common at smaller enterprises, affecting 6.9% of small and medium-sized companies and 7.9% of small businesses. Teikoku Databank noted the rapid recent rise in risk for such firms.
