Before you book anything, I thought you might want to know who you're actually spending the day with.

​

For a decade, I built my career in corporate Japan — three years in sales, five years coaching English one-on-one, and three years in customer satisfaction management. Wherever I went, I delivered results. But I never quite felt satisfied. That quiet conflict eventually gave me a realization: I wanted to take my strengths and challenge myself, fully, in my own life — to put the kind of service I could picture in my head out into the world, and grow the number of people made happier by it.

 

Travel gave me something different at every milestone along the way. In India, living with almost nothing, I saw how different daily life could look on the surface, and yet how remarkably similar people's lives really are underneath it — a realization that left me with a quiet confidence that I could build a life almost anywhere. And through all of it, one thing was always true: what stayed with me longest was never the place itself, but the people I shared it with.

 

Somewhere between that and my background in hospitality, an idea started taking shape that I couldn't let go of.

 

I’ve always believed that the most extraordinary service comes from people who aren't just doing a job, but living their passion. For me, guiding and hospitality are not a routine profession — they are my life’s work. When you truly love what you do, every detail and every effort becomes pure joy.

​

That is the foundation of SINCERE: a fully private, fully tailored experience driven by genuine passion. Some clients are visiting Japan for the first time; others have been many times before and want to go deeper. What sets it apart is how far the customization actually goes — one lawyer I guided ended up inside an actual court hearing, simply because that's what genuinely interested him.

 

Whatever pulls at your curiosity, that's where we go. If it's food, I'll take you to a local sushi spot with the atmosphere and prices locals actually get, not the one in the guidebook. If it's history, I'll walk you through the real story behind the places we visit. That same instinct lets me show you something a travel agency can't package: real neighborhoods, walked the way locals walk them, and a genuine feel for how people here live.

​

Above all, my goal goes beyond showing you the sights. I want to deliver a moment of genuine awe — an experience so authentic and deeply tailored that it gives you a chance to pause, reflect, and perhaps find something you’ve been searching for in your own life.

​

I was made for this work — every day here only confirms it.

 

I look forward to creating an unforgettable journey with you.
