Recent reports have shed light on the phenomenon of "dark patterns" prevalent in Japanese e-commerce websites and digital services. These user interface designs manipulate customers into making purchases they didn't originally intend. The urgent issue has grabbed wide attention, instigating calls for implementing tighter regulations to protect consumers. The cases are seen in a wide range of service types and have generated discussion on consumer rights in the midst of a growing online shopping trend.

In Japan, public concern is rising over these dark patterns, especially in light of the explosion of e-commerce due to the COVID-19 pandemic. There is a strong sense of urgency and demand for action, amplified by Japan's cultural respect for consumer rights and established legal frameworks designed to protect them.

The dark pattern phenomenon is not unique to Japan. In the EU and US, pending bills or established laws are in place to regulate such designs. In the US, the Federal Trade Commission has been urged to investigate dark patterns, and there are anti-dark pattern bills awaiting Congress' approval. In the EU, the phenomenon is monitored under the General Data Protection Regulation (GDPR).
