About Kazuna Lab

The Reset Method

Philosophy

It's okay to stop. If you keep taking steps forward, each one will change your future.

"It's okay to slow down if you're struggling"—this is what I myself wished someone had told me.

For those who push themselves out of fear that "stopping means the end of my career" or "resting means being left behind," we want to say: "It's okay to stop. You can always start walking again."

Kazuna Lab focuses not on recovery after breakdown, but on prevention before it happens. For those who haven't fallen but aren't at their best—we help them avoid falling, move toward their peak performance, and maintain their well-being.

Start fresh, as many times as you need.

My Story

Lessons from 200+ Hours of Monthly Overtime

I once worked over 200 hours of overtime for six consecutive months. One month peaked at 250 hours. I often found myself greeting the morning at the office, taking naps on chairs lined up together.

At the time, I didn't feel it was "hard." I thought it was normal. But looking around, I noticed my colleagues gradually losing their smiles and becoming exhausted. Watching a once-cheerful senior colleague lose their energy deeply affected me, leaving me with a sense of helplessness—"There's nothing I can do."

Discovering Running

I discovered running after picking up a book called "Marathon Junkie." A sudden feeling arose: "Maybe I can become a different person." Without overthinking, I joined an early morning run at Tokyo's Imperial Palace. Luckily, I got to run with the author.

That experience taught me through my body—not "whether I can do it," but "just try it first."

Ultramarathon Completion and "The Power to Rest"

Running gradually led me to attempt an ultramarathon (100km). I finished, but pushed myself so hard that around the 70km mark, my urine turned reddish-brown.

This experience showed me how much strain "overdoing it" puts on the body. I realized the importance of "challenging without overstraining"—progressing at your own pace, little by little.

"No-Time Pochi-ri" (Just Do It)

A phrase I treasure is "No-Time Pochi-ri"—acting on your heart's voice without overthinking, then taking responsibility and planning afterward.

If you feel "staying as I am is a waste" or "I really want to become someone different," try "No-Time Pochi-ri" on whatever interests you.
