CHANT CEO Tanioka appeared as a guest on "Sotokoto Radio", which aired on Friday, November 8, 2025! 🎉
"Sotokoto Radio" is a highly informative program that explores various social issues from the perspective of "related populations", a key concept that supports regional revitalization and vitalizes exchange between rural and urban areas.
I participated in a talk session with personalities Chie Kurose (CEO of Sophia Planning Co., Ltd.) and Mizuho Onuma (former House of Councillors member, associate professor at Taisho University).
A connection with a best friend from high school!
In fact, Mizuho Onuma, one of the guests, and Tanioka, CEO of CHANT, are best friends from high school, which led to this opportunity to appear on the show! I believe we were able to have a relaxed and in-depth conversation thanks to our long-standing acquaintance.


She also appeared on an Instagram live stream before!

Here are some of the topics that generated particular excitement!

- CHANT's initiatives to create a "related population": New connections between urban and rural areas born from product development.
- Differences between TANE and KIYOME: The features of the two types of all-in-one shampoo bars.
