Kyani Equipment Services is a locally owned, family-run business based in Kalaheo, Kaua‘i. Founded by Tyson Yamashita in 2010, the company was built from the ground up by a local operator who knows the land, the lifestyle, and the level of trust it takes to get work done right on this island.

Raised with values that don’t waver — hard work, honesty, and taking care of people — Tyson launched Kyani Equipment Services while still working full-time in the Operators Union, running heavy equipment. Today, his team delivers the kind of personal service and high-performance results that only come from living here and doing the work firsthand.

Helping Landowners Take Back Control

We help Kaua‘i landowners clear, clean, and reclaim their properties — whether it’s fast-growing brush, prepping for a new build, cleaning up for sale, or just taking back control of a yard that’s gotten out of hand.

From realtors looking to boost property value to homeowners needing help with their land, we show up with the tools, experience, and hustle to make it happen.

Not every job is straightforward — and that’s exactly why clients call us. If you’ve got land that needs attention, big or small, we’ll find a way to get it done.
