Nanakai at Prague Tea Fest

In February 2026, Nanakai will appear at the Prague Tea Fest. Not as a performance,not as a workshop,but as a quiet practice shared in public. Wagashi will be shaped by hand,tea utensils will rest on the table,and time will slow down for a moment. This journal is a note on why bringing such stillnessinto a busy, open space matters to me now. Prague Tea Fest is a place where many traditions briefly cross paths. Tea travels easily across borders, carrying habits, gestures, and ways of listening.In Prague, a city shaped by layers of history, these paths meet without needing to merge. The festival is neither a temple nor a marketplace.It is a space in between,where hands, cups, and conversations pause long enoughfor something unfamiliar to be felt. Making wagashi in front of others is not about teaching a technique. I do not explain each movement.I let my hands work before words arrive. Wagashi exists only for a brief moment.It is shaped, held, and then disappears.What matters is not the finished form,But the moment it comes into being. Each piece reflects an inner landscape.A state of mind, a breath, a quiet shift inside the body.No two shapes are ever the same,because […]

Creating “yukocoolsummer.com” as a Place Together with AI

How yukocoolsummer.com Came into Being Quietly, but unmistakably, a website has come into existence. 👉 yukocoolsummer.com From a technical point of view, the site was built in roughly thirty hours, exactly as my AI collaborators had planned.Yet when I counted the actual days between the first step and completion, I realised it had taken almost two full months. I can almost imagine the relieved faces of my AI advisors now.Thank you. Truly. The Beginning: Before Any Design Existed The first two days were spent entirely on groundwork:choosing a server, comparing tools, deciding how and with what to build. I was a complete beginner.Every unfamiliar word, every unclear setting, every doubt went straight to my AI collaborators. I must have asked well over a hundred questions. They never grew impatient.They answered again and again, clearly and calmly. This, I believe, is one of AI’s greatest gifts:you can ask as many times as you need. After comparing several options in terms of cost, purpose, usability, and uniqueness, I finally chose ConoHa as the server and THE THOR as the theme.Wix was a strong final candidate. I thought the rest would be smooth. It wasn’t. When Building a Website Becomes Self-Inquiry Creating the […]

A blog will also grow here, in time.

This journal is a quiet place for what remains. I began writing in 2021. I began sharing my writing publicly in 2024.Since then, my work has slowly taken the shape of a three-part book. The first part, which I am currently publishing on Substack, explores meditation and my personal origins.It traces how I returned to Japanese culture, Japanese spirituality, and the world of tea,and how, through meditation, I encountered my ancestors within myself.It is also the story of beginning kendo,and of learning through the discipline and philosophy of Bushidō. The second part grows from that practice.It reflects on what kendo taught me, not only as a martial art,but as a way of meeting fear, ego, and silence through the body. The third part is still unfolding.It begins with travel and meditation,with the slow integration of shadow and light, yin and yang.And then, unexpectedly, it arrives at wagashi. Through nerikiri, shaped by hand,I began to meet what I had hidden or avoided within myself.Making wagashi became a way of seeing, holding, and transforming those inner states,quietly, without force. This blog is not the book itself. Here, I write what comes after.Small realisations that appear after finishing a chapter.Thoughts that arise after […]
