TOKYO, Sep 16 (News On Japan) - More than 80% of internet users in Japan say they have encountered so-called "dark patterns"—web or app design practices that mislead consumers into accepting unfavorable contracts or purchases, according to a survey conducted by an internet industry group.
The study found that 86% of respondents had been exposed to dark patterns such as automatically renewing subscriptions, hidden conditions written in small print, or websites that make canceling contracts unnecessarily complicated. Around 30% reported that they suffered financial losses in the past year, with damages estimated to reach nearly 1.7 trillion yen annually in Japan.
Examples of dark patterns include countdown timers designed to pressure purchases, claims of limited stock or exaggerated numbers of viewers, and pop-ups urging immediate decisions. Other tactics involve free-trial offers that automatically convert into costly subscriptions or misleading discount campaigns. Many respondents also noted frustration with cancellation processes that force them to call by phone or search online for how to cancel, despite initially signing up through a website.
Experts warn that such designs exploit consumer psychology by inducing panic, urgency, or trust through fake customer reviews. In some cases, services request unnecessary amounts of personal data, raising concerns over privacy violations.
Industry groups have responded by forming the Dark Pattern Countermeasures Association, which promotes awareness of deceptive practices and plans to certify websites that operate transparently. They emphasize the importance of taking screenshots when suspicious terms appear, as many websites are deliberately designed so users cannot later review the conditions they agreed to.
While dark patterns may temporarily increase sales for companies, experts caution that reliance on such tactics risks eroding brand trust in the long term. Efforts are now underway to encourage ethical design standards and reduce consumer harm.
