01 · 経路 The route in

Agriculture first, then the wheel

He was born in Tokoname, a place that makes bonsai pots, to a father who makes them. He went round by way of a graduate degree in agriculture at Shizuoka University, then trained in wheel work and other techniques at the city's ceramic training centre, and then came to the family kiln.

His specialisms are glazed hand-building (tebineri) and slab-building (tatara). Alongside the bonsai ware he also makes modern pieces meant for Western rooms.

02 · 家伝 The family green

A named glaze

The most telling piece currently known is a hexagonal pot with cusped-window panels, glazed in green. The glaze is given a specific phrase: 家伝の緑釉 — the family's green.

家伝の緑釉 — the family's green.

03 · 落款 The mark

One mark

樹晃 is the only form documented here. No impression of it is documented here, so there is nothing to match a pot against.

Our record also notes two forms that appeared in earlier unsourced text — 晃 and 樹晃造 — but they are not among the forms currently documented here. Their status is unverified. Where a pot carries the kiln name as well, see Koyo.

Recorded works

Not for sale — three works recorded for this maker. Only one carries a size.

Work Size (cm)
Unglazed rectangle, outer rim, indented corners — a classical, refined form, of the kind called Shōkōdō, with the drip edge left off. He is often thought of as a glaze specialist, and he does have many excellent glazed works — but his unglazed work shows real distinction too—
Keiketsu-glazed rectangle — another form copied from an old Chinese pot, the body curve soft. The glaze is neither the usual selenium red nor iron red; copper in the mix is the suggestion. Part of it turned green through kiln effects, creating an interesting surface—
Green-glazed hexagon, outer rim — the family green, over panels framed in the cusped window outline. Quiet colour and quiet decoration, and they agree with each other13.5 × 7.3

05 · 展開 Widening out

Pots, and then some

Lately the range has widened: unglazed pots, flower vessels and water trays, tableware, interior pieces, creative teapots.

The note on the unglazed work is worth keeping. A maker taken for a glaze man turns out to have a sure hand in bare clay as well.
