I have consulted with over 3,278 companies on web design, microcopy, trust formats, and other improvement methods based on A/B testing and data analysis of web pages. Since 2017, I have held the first Microcopy writing workshop in Japan and have conducted tests with over 2,364 client companies, mainly e-commerce business owners throughout Japan. In my own company, Orecon, I have executed more than 1,663 case studies in Japan and abroad. The clients I consulted with improved their conversion rates by 50% and sales by 13 times in just 15 minutes, for a total improvement of more than 416.8 million yen throughout my career.Also, We run a website called Darkpatterns.jp(https://darkpatterns.jp). There are many deceptive patterns in Japan , just as they are prevalent around the world. We are working to reduce the number of consumers who are deceived as much as possible.
