Board-certified neurologist and headache specialist. After clinical work and research in the Department of Neurology at The University of Tokyo, now focuses fully on headache care. Headache diaries are essential to headache care, yet many are still kept on paper, and most apps on the market are hard to use. To solve this, built the headache diary app Zutsu Note. Also works as an engineer, a "headache specialist who builds," and approaches headache care from both the clinic and the development side.

Headaches aren't something you just have to put up with. They're something you can learn to manage. Finding a headache clinic that's right for you is an important first step.
