White porcelain and earthenware, made on the same island. Amakusa yields both porcelain stone and clay, and the kilns are distributed across the island rather than gathered in one place. Porcelain stone produces white porcelain; the clay produces the heavier earthenware known as tsuchimono; and because both materials occur here, two quite different kinds of ware are made within the same district.

Having two raw materials available means each kiln can choose what it works with, which widens the range of what the island produces and makes the district considerably harder to summarise in a sentence. The kilns are scattered rather than clustered because each established itself near the material it uses — an arrangement that made sense when moving raw stone or clay any distance was the largest cost involved. Kumamoto is about two hours away by car. Bridges connect the island to the mainland, so it is not isolated in the way islands usually are, but getting around within it assumes a vehicle of your own.

A dispersed producing district holds together less well than a concentrated one. What it gains in exchange is proximity to its materials, which reduces haulage and leaves each kiln more independent than it would be inside a cluster — and independence, over time, produces divergence. That is why Amakusa ware makes a weaker single impression than other districts of comparable size, and why it is harder to describe in one sentence. There was never one producing district here; there were several, sharing an island and two quite different kinds of ground.
