About RKwoodshawaii

RKobayashi 2017-6311     RAYMOND KOBAYASHI, JR.

Owner- Wood Crafter

As a long-time Big Island home builder, using local wood in his homes has been Ray’s passion.  Examples of the 500 homes built by R.K. Builders, Inc. can be found in almost every Hilo and Puna subdivision.

In his own lumber mill, Ray is able to take a tree log, dry it, trim it and use it to create finished pieces.  His own residence features koa and eucalyptus ceilings as well as koa and sugi pine walls and cabinets.

Koa is scarce and becoming more difficult to obtain, resulting in higher prices.  As a result, Ray has begun creating carved mango doors, mango rocking chairs and mango barstools.



Manager/ Sales Coordinator

Ray creates the products, and wife Gloria markets them.  Using her experience as a long-time Realtor and retired educator, she is responsible for quality control, pricing, and developing online sales and marketing of furniture, koa jewelry boxes and koa and mango urns.
