Activities

Nice to meet you. We are Tsune Quartet.
I write about my daily realizations and learnings on the themes of "knowing," "thinking," and "challenging."

Geography, history, science, philosophy, and other topics that are a little more serious,
We also talk about the Guinness World Record challenge and manufacturing.
This is the place where all information is sent out.

A random question may lead to a new discovery for someone.
With that feeling in mind, I write every day.
