Ho Yoku Japanese Pumice – Imported Bonsai Soil Aggregate for Drainage & Root Health

Japanese Pumice – The Gold Standard for Precision Bonsai Soil

Imported directly from Japan, this premium pumice—also known as Hyuga Pumice—is favored by serious bonsai professionals for its structure, weight, and performance. It’s the same aggregate we use at New England Bonsai Gardens on high-value imported trees and specimen bonsai in refinement.

Sourced from Japan’s volcanic plains and carefully sieved to remove dust and fines, Ho Yoku Japanese Pumice offers the ideal balance of drainage, moisture retention, and aeration.

What Makes Japanese Pumice Special?

• Heavier and more angular – it stays in place and holds its shape over time
• Highly porous – absorbs and releases moisture consistently
• Preferred for high-end bonsai – especially in refinement or show conditions
• Imported and limited – which increases cost, but delivers unmatched quality

This pumice is ideal for growers who want total control over their soil blend and root development—especially when working with prized or delicate trees.
