Yamaaki

山秋

Two generations

Recorded in 2006 as the largest maker of high-grade Tokoname bonsai pots. It ran two quite different things under one name — ware made in numbers, and handmade pots made singly or in short limited runs — and the mark is what tells you which one you are holding.

01 · 落款 The mark

Which of the two lines is this?

The record describes two quite different things sold under one name, and telling them apart is the first thing to do with a Yamaaki pot.

The marks separate them. 山秋造, stamped, goes on pots made in some number. The 松泉 marks, nail-carved or stamped, go on the handmade line.

You can call it handmade only when the mark says 松泉.

So a Yamaaki pot can be called handmade only when the mark is one of the 松泉 family. If the mark is 山秋造, it is from the other line — which is not a criticism of it. On the one such pot currently known, the form is well proportioned and the clay falls between udei and shidei, and that it is finished too well to be spent on everyday growing.

02 · 年代 Dating

1985, and 1995

Two dates, and both of them come from the second generation's name rather than from the pot.

He began signing 小松泉, Ko-Shōsen, around 1985, and took the name 松泉 after his father died in 1995. So a handmade pot marked Ko-Shōsen falls between those years; one marked Shōsen came after. Neither tells you the year.

Further back is the first generation's own ground, the pre-war pots carrying 金華造印. His page is here.

03 · 土 The clay

Tokoname udei, and who made it

The clay most associated with the house is 常滑烏泥, Tokoname udei, and it is credited to the second generation: zisha bought in from China, blended with Tokoname clay. It produced a great many followers.

Which is worth knowing when another kiln offers you a Tokoname udei pot — it may be one of them.

The first generation's contribution was a different body: 山秋焼, Tokoname clay mixed with chamotte and sawdust and fired to an open, porous state.

04 · 窯 The kiln

One of the largest gas kilns in Tokoname

It is a bell kiln, and the firing it gives has a name for being steady.

Forming is press-moulding finished by hand. Glazed pots and small pots are made, but the main line is unglazed clay in medium and large sizes.

05 · 落款 The mark

Four documented marks, and a calendar

Read this table as a calendar and a spec sheet at once. The first two place a pot between the name changes. The third tells you it was made in numbers. The fourth belongs to the first generation.

Other kilns use their marks the same way, for different distinctions. Yamafusa marks grade on the older pots and era on the newer; Gyōzan Nakano separates slab- and coil-built work from moulded. Neither of those readings applies to Yamaaki’s marks.

Mark Reading Note
松泉焼 / 松泉焼山秋造Shōsen — nail-carved and stampedHandmade pots, after he succeeded to the name in 1995.
小松泉作 / 小松泉造Ko-Shōsen — nail-carved and stampedHandmade pots, before 1995.
山秋造Yamaaki-zō — stampedPots made in some number. Not made singly.
金華造印Kinka-zō-in — wording onlyPre-war, the first generation's. Only the wording is known; there is no impression of it.

Read the mark before the price

Only the 松泉 marks indicate a handmade pot. 山秋造 is the other line.

Recorded works

Not for sale — works recorded for this house. They span it: the first is the first generation’s, the second carries the production stamp, the third is the second generation before he succeeded, the fourth after.
