What is Atopiyo?
Atopiyo is Japan's first app dedicated to supporting the early recovery of eczema (atopic dermatitis) patients through the unique power of images, not just text. It enables users to anonymously track and share their skin symptoms, itching and skincare.
Founded by Ryotaro Ako, a former eczema patient, Atopiyo launched in July 2018 and has since received 11 awards, including the prestigious Ministry of Health, Labor, and Welfare's "Extend Your Healthy Life Expectancy! Award". As of October 2024, Atopiyo has grown into Japan's largest eczema community, boasting 29,000 downloads and 66,000 user-submitted images. Users have responded positively, giving the app an average rating of 4.5 out of 5 on the App Store and 4.0 out of 5 on Google Play.
We are currently advancing big data analysis and disease awareness in eczema through collaborations with Keio University and six other university and national hospitals, as well as partnerships with pharmaceutical companies.

Representative・Developer
Ryotaro AKO
Former atopic dermatitis patient. Developer. Masters degree in engineering. Certified public accountant.
Because of his experience with three allergic diseases: atopic dermatitis, asthma, and rhinitis, he engaged in volunteer activities at patient groups. He then developed this app after interviewing people with atopic dermatitis, with input from pharmacist Akiko Ako and the guidance and supervision of developers.
After completing the master's program at Keio University Graduate School of Science and Engineering, Ryotaro passed the certified public accountant examination. After working at Ernst & Young ShinNihon LLC and Renova Co., Ltd., he then established Atopiyo LLC.
Background
After his experience of suffering from atopic dermatitis in childhood, Ryotaro Ako learned programming and developed "Atopiyo", an app for visualizing atopic dermatitis, based on interviews with people with atopic dermatitis, the opinions of pharmacist Akiko Ako, and the guidance and supervision of programmers.
With atopic dermatitis, the itching continues even when you sleep 24 hours a day, and since the symptom can draw other people's attention, it can have a big impact on your mental health. This app aims to provide support for early recovery by providing a place for people suffering from atopic dermatitis to (1) control their symptoms and (2) exchange information with each other. The aim is to collaborate with pharmaceutical companies, medical institutions, etc., and contribute to research, research, product development, and disease awareness in the field of atopic dermatitis.
