I started Trademark Wagon with a mission to support overseas clients who plan to start or run a business in Japan, in the trademark field.


I worked at a Japanese automobile company where I was in charge of international trademarks in more than 100 regions or countries. I handled trademark prosecutions, International Registrations under the Madrid Protocol, renewals, agreements and contracts, trademark assignments, disputes and lawsuits, and so on. 


Then, I made a career shift to work as a trademark attorney at one of the major patent attorneys offices in Japan. I supported both Japanese clients and overseas clients in trademark matters.


I was a member of the Small and Medium-Sized Enterprises and Start-ups Support Committee formed under the Kanto Branch of Japan Patent Attorneys Association in the year 2018 and 2019, and am now a member of the Trade Facilitation Measures Committee formed under Japan Patent Attorneys Association from April 2021. I also serve as an International Business Advisor and consultant of G-JIC (Global Jinzai Ikusei Center) from April 1, 2018 and as an advisor at the Permanent Intellectual Property Consultation Center operated by the Kanto Branch of Japan Patent Attorneys Association from April 1, 2019, until now.

I delivered a lecture in the "Intellectual Property Seminars 2018" hosted by the Kanto Branch of Japan Patent Attorneys Association in October 2018.


At the desk...

Trademark is deep. I learn something new and interesting every day.  I love coffee especially with a lot of fresh milk. 


After leaving the desk...

I love birds, both wild birds and companion birds. Looking at birds in the city will never make me bored. Yet, what I have now is a dog, who loves chasing birds….

I’m a member of Wild Bird Society of Japan, Small Birds Rescue Association and other bird rescue association in Japan.
