We grow the best divers on Earth.

Pinnacle Diving Company is an American veteran-operated English-speaking professional diving service based in Kanagawa, Japan, and we nurture and grow the best divers on Earth.

It's a bold thing to say, and we know it. Yet we also know for a fact that amazing divers must be "grown" by leaders capable of solid mentorship, and this is exactly where Pinnacle Diving Company comes in.

We have a passion for diving. Our adventure is exploring the world-over, our mission is to teach, train, certify, and mentor, hands-down, the best divers in the world, and our goal is to grow a competent, confident, capable, and safe dive community, that truly cares about the health of the oceans, the planet, and each other.

Perhaps the biggest service PDC provides is "mentorship", and best of all, we do it for free!

Mentorship is an essential component to the growth of an individual in any field, occupation, or activity, and a key aspect to your progression.

The willingness to seek out guidance and be receptive to constructive feedback not only helps us all improve, it provides us with opportunities to see things we couldn't see for ourselves, and demonstrates good character traits critical for activities such as diving.

PDC staff are always teaching, coaching, mentoring, and guiding certified divers to help them improve their skills, maintain proficiency, grow as divers, and to enjoy diving to the fullest.

PDC believes in "diving for a purpose", and there are opportunities to practice, improve, and grow on every dive.

From recreational to technical, not only do we dive for fun, but we routinely practice skills proficiency, progression, continuation training, and maintaining currency, all while enjoying being in the water, and we openly invite certified divers of all levels to engage us in helping them improve, even if only in some small way.

While we're enjoying time spent underwater, feel free to ask us for tips on improving something you've been struggling with or don't feel confident about, or even simply practicing something you want to maintain proficiency with, and we'll work it into the dive.
