Vision & Mission / What we are building
A future where yakuzen wisdom is simply part of life for everyone.
We are building a platform that works as infrastructure for yakuzen practitioners working on their own, so that the value of yakuzen circulates fairly. The constitution check is the door that connects people to yakuzen.

Find a professional / Find a practitioner
Search by specialty and meet a practitioner you can trust.
You can filter by qualification, school and specialty. Only people holding the Kokusai Yakuzenshi (international yakuzen practitioner) qualification are listed.
What comes after the qualification differs from person to person. Some opened a school, some supervise recipes for companies, some launched their own yakuzen tea brand. One of our eight registered practitioners, someone whose path is close to yours, will take 45 minutes online with you.
These sessions are about how to use yakuzen and where to take your career. They do not involve diagnosis, treatment, medication or any other medical act.
OEM, product development and supervision, matched to the right practitioner.
When you want to work with a yakuzen practitioner on recipe development or supervision for a new product, we bring in the right expert and drive the project with you.
