I am currently a fourth-year mathematics student at Chiba University, Japan.
My graduation seminar focuses on commutative algebra under the supervision of Professor Sato.

Miscellaneous
Running
I started running in October 2025 after I was hit by a taxi.
Since I used to be obese (肥満体) back in 2023, running has now become a way for me to maintain my weight.

Triathlon
After completing my first full marathon in April 2026, I plan to sign up for an IRONMAN 70.3 triathlon in the near future.
(Once I have invested in a decent bike, the biggest investment I will need is simply enough time to exercise.)
