About

From the hotel floor
to the codebase.

Hotel General Manager from 2017, then running my own hot spring ryokan from 2018 — bookings, marketing and guest relations, all by hand. What I build now is what I wanted back then.

Shingo Kumon — MUSUBU Tech

Why

The hospitality went into paperwork.

Hotel work is about hospitality. But in reality, most of the staff's time was consumed by tasks — answering calls, transcribing reservation books, replying to emails, checking inventory.

Throughout my hospitality career, I kept asking myself: "What if we could spend this time on the guests instead?"

Now I'm building that answer through technology. Because I know the frontline, I can build tools that actually get used. Because I understand the business, nothing I build is "delivered and forgotten".

Timeline

How I got here.

Hotel General Manager from 2017, then running my own hot spring ryokan from 2018 — handling bookings, marketing and guest relations on the floor. I started building software in 2023 and founded MUSUBU Tech in 2024. That frontline experience is the premise behind everything I build now.

2017
General Manager
Oversaw full hotel operations — people, finances, and service quality.
2018
Running a Ryokan
Started operating my own Japanese inn. Managed reservations, marketing, and guest relations single-handedly.
2023
Discovered AI
"Could AI handle all this manual work?" — I stepped into the world of technology.
2024
Founded MUSUBU Tech
Built MUSUBU — a LINE×AI reservation SaaS. A product built by someone who knows the pain firsthand.
2025
The Orchestrator
Combining AI, tools, and systems to automate businesses. Not just writing code — conducting the whole operation.

Values

Three things I hold to.

ORCHESTRATE, DON'T JUST CODE

Writing code is only part of the job. The real work is combining AI, tools, and people to design the optimal solution.

BUILT FROM THE FRONTLINE

Tools built without frontline experience don't get used on the frontline. Firsthand operations experience is the foundation of everything I build.

AUTOMATE THE BACKSTAGE

Technology belongs behind the scenes. What the customer sees should always be human warmth. Automate everything backstage — relentlessly.

Let's work together

Ready to automate the backstage?

The spec does not have to be settled. We can start by working out which part is worth building.
