Akadama (red ball earth) is a volcanic byproduct mined exclusively in Japan. It is in some ways similar to clay, but with a unique microscopic structure that makes it ideal for bonsai use. Akadama is excellent as a component in bonsai soil as it retains nutrients. It also allows roots to grow through it and breaks down over time. Akadama is a key component in nearly all quality bonsai soils.
The shipping process will break down some of the Akadama so it will need to be sifted prior to use. The fines in Akadama restrict aeration within bonsai soil so need to be removed prior to repotting. The fines can be saved and mixed with sphagnum moss and sphagnum peat moss to create muck which is commonly used in forest plantings.

We supply a variety of brands including Kobayashi, Kotobuki, Double Line and Ibaraki.  In my opinion they all seem to be of equal quality.

Akadama Grain Sizes Available:
2mm or 2.5mm - Extra Small Size - @ 1/32" - 1/8" - For Very Small Trees (Shohin, Mame)
5mm - Small - Standard Bonsai Use @ 1/16" - 1/4" - The Most Common Size
7mm - Medium - Most pieces @ 1/4" and 1/2" - Many Use It For Larger Trees and Some Pines.  I use it as part of my drainage layer and for some pines.

Akadama Bag Sizes Available:
13 Liters - A full Japanese bag of Kobayashi  About 3.44 Gallons
14 Liters - A full Japanese Bag of Double Line, Kotabuki, or Ibaraki - About 3.7 Gallons

All of these brands are very similar in terms of hardness when completely dry.  We strive to import the hardest Akadama available to the United States. 

This is a hard quality Akadama imported from Japan.

  • Akadama is a semi-hard substance that can be crushed in your hand.  It is softer when wet and harder when dry.  When dry it is nearly as hard as rock.
  • Perfect for adding to your own bonsai mix
  • This product will need to be sifted prior to use to remove any fines that accumulate from the shipping process.  Normally fines 1/32" or smaller are less than 5% in the 5mm bags.  Fines can be used to make muck. Wear a mask for safety.
  • Prior to shipping from japan this product was sieved to be the appropriate size.

Great soil component

I mix my own bonsai soil and for my conifer mix I always include Akadama. It works well with deciduous trees as well as a main component but different amounts. Akadama will break down over longer periods of time however by repotting on a regular schedule it holds up very well.

I tried this for the first time last year, and this year I came back for more and got 8 bags of it. Superfly provides a high quality product at a good price, has good customer service, and ships fast.
