Product details

The Kujira Osono 50" is designed as a large fire pit and modern hearth for patios, decks, and backyard settings. Its bowl-shaped cement vessel creates a clean, circular silhouette that complements contemporary and traditional landscapes alike. The UHPC construction provides dense, durable material that holds heat and resists the freeze–thaw cycles common in outdoor environments without compromising the artisan matte appearance.


Fuel and burner

This fire feature ships with an HPC Match Light burner sized for the 50" bowl and is set up to operate on either natural gas or liquid propane; it is a luxury gas pit solution for anyone seeking a reliable patio heater or backyard heating element. The included tumbled Mexican lava rock conceals the burner and creates a natural-looking flame bed suitable for social spaces and ambient lighting. For propane fire setups, follow local codes and use an appropriate regulator and tank placement.


Materials, finish, and care

Handmade in the USA from UHPC, the Osono Model is crafted by artisans and finished with a natural matte surface that minimizes glare and highlights texture. Routine care is simple: keep the bowl clear of debris, cover during extended wet or freezing conditions if possible, and remove excessive soot or residue from the lava rock after heavy use. Avoid using harsh chemical cleaners that could alter the Kujira concrete color or finish.


Installation guidance

Because the 50" bowl weighs 280 pounds, plan for a stable, level base—concrete pads, compacted gravel, or pavers are appropriate. Consider professional installation for gas line hookup to ensure the burner and propane or natural gas supply meet local codes. The unit functions as a permanent fire feature when set on a fixed base but can also be integrated into custom landscape designs as a standalone round stone pit focal point.

The Nature of Concrete


KUJIRA products are handcrafted one at a time using a custom concrete formulation designed to endure. Because concrete is a living material, each piece carries its own distinct character—soft tonal shifts, organic texture, and natural variation. This individuality is intentional, embracing the material’s honesty and making every KUJIRA piece truly one of a kind.

Holes & Pock Marks

Naturally occurring air pockets formed during casting.

Color Variation

Subtle shifts in tone are inherent to concrete and vary from piece to piece.

Texture & Flow Lines

Organic movement created as the material settles and cures.

Connection Seam

A visible line where molds meet — intentional, honest, and structural.
