Hello from Shinjuku, Tokyo! 🇯🇵
I am the CEO & Founder of Jon & Coo Inc., and I’m currently building a "Culture OS" to connect the world.
Software Engineers often talk about "Optimization" and "Efficiency." But look around. People are more connected than ever, yet we are lonelier than ever. We optimized our communication, but we lost our "Heat."
That’s why I decided to build a platform based on Japan’s most powerful social technology: The MATSURI (Festival).
🏮 What is "Matsuri"?
In Japan, a Matsuri isn't just a holiday. It is controlled chaos. It’s where boundaries between strangers dissolve. It’s where the quiet Japanese society suddenly explodes with energy, music, and unity.
My mission? To digitize this energy.
I am building a platform called "Matsuri" (part of my Culture OS). It’s not just an event app; it’s an engine to spark real-world interactions, like our "Night Picnics" in Shinjuku, where locals and global travelers mix without barriers.
💻 The Tech: Orchestrating the Chaos
Building a platform that manages real-time cultural experiences requires a robust yet flexible stack. Here is how I’m engineering the "Matsuri":
The Backend: Django (Python)
Why? Managing communities, user karma, and event data requires structure. Django’s stability allows me to focus on the business logic of "connecting people" rather than reinventing the wheel. It handles the heavy lifting of our ecosystem.
The Frontend: Next.js 14+ (TypeScript)
Why? A festival is dynamic. The UI must be fast, responsive, and alive. I use Next.js to deliver a seamless experience, whether you are browsing on a laptop or checking in at a chaotic street party in Tokyo.
The Design Philosophy:
I treat UI/UX not just as "screens," but as "Omotenashi" (Japanese Hospitality). Every interaction should feel welcoming and intuitive.
🌏 Refactoring Society for World Peace
As a developer, when I see a bug, I want to fix it. I believe "Loneliness" is the biggest bug in modern society.
My approach isn't to build a Metaverse where we escape reality. My approach is to use Tech (AI & Web) to enhance Reality.
I am refactoring the way people meet. I am rewriting the code of "Socializing." By combining Ancient Japanese community concepts with modern Web technology, I aim to create a world where everyone can find their tribe.
🚀 Join the Picnic!
I am currently working on scaling this "Culture OS" from Tokyo to the world. It’s a messy, exciting, and challenging journey involving large-scale refactoring and community building.
text me anytime:)
I’ll be writing about:
How to build community-driven apps with Next.js & Django.
The struggles of a Non-English native founder going global.
How to apply Japanese philosophy to Software Engineering.
