Awabancha tub
阿波晩茶 漬け込み 桶 · Awabancha fermentation tub · 阿波晩茶の桶
A large wooden tub used in Tokushima to ferment heated, worked Awabancha leaves with their cooking liquor. Its size and construction details are not specified in the sources.
Regional history
Awabancha is a household tea associated with the mountain districts of Tokushima, including Kamikatsu, Naka and Minami. It was historically made mainly for home use and sharing with relatives and neighbours; production later also supported household trade. The 2021 designation by Japan's Agency for Cultural Affairs recognizes the regional production technique. It does not date the first use of this tub, which remains unknown. The tub is one part of a wider seasonal practice that runs from harvesting later-grown summer leaves through cooking, working, fermentation, drying and selection.

The tub and its role
The Awabancha tub is the vessel at the wet fermentation stage. It holds tea leaves after they have been heated and worked, together with liquor retained from cooking them. The regional account describes a large wooden tub, but gives no capacity or measurements. “Tub” is not a standard model specification: the sources do not identify a wood species, exact joinery or universal design. A current producer likewise shows and describes a tub or barrel in use, but this contemporary example does not establish one design for every household or district.
Packing and fermentation
Producers cook the summer-harvested leaves in a large kettle, then rub or work them so their surfaces are marked; the regional account says this helps fermentation proceed after packing. The tub receives the worked leaves and their cooking liquor. They are packed down and covered for lactic fermentation. In the detailed heritage account, banana or palm leaves may line the cover to close gaps, natural stones weigh it down, and cooking liquor fills the vessel. Packing and covering aim to expel trapped air and seal the ferment. A national agriculture feature describes summer tub fermentation lasting two weeks to one month, followed by drying. Those durations describe the tea process, not a capacity specification for the vessel.

How it differs from other tea vessels
The tub contains the packed leaves and cooking liquor during summer fermentation. Compression and a close cover reduce spaces where air remains, while the liquor keeps the leaves in the wet stage. This differs from the preceding cooking vessel and the later drying surface: the tub is for fermentation, not boiling or drying. Awabancha has one fermentation stage. The Ministry of Agriculture contrasts it with Shikoku teas such as Goishicha and Ishizuchi-kurocha, which have an earlier mould stage before lactic fermentation. An Awabancha tub should not be confused with a steamer or the room used for another tea's first stage. The records give no purchase route, cleaning routine, storage practice or stated limitation for this particular equipment; no general instruction is inferred from its traditional use.

History
Awabancha is a household tea of Tokushima's mountain districts. The technique has been practised for family use and sharing, and later also as a household trade. Its documented range includes Kamikatsu, Naka and Minami. The 11 March 2021 designation recognizes the production technique, not the invention or first use of the tub. The vessel form itself is not dated.

Made of
- Wood — Tub body
A large wooden tub is documented; wood species, joinery and dimensions are not specified. - Natural stones — Weights on the cover
Natural stones hold the cover down in the regional method; their number and mass are not specified. - Plant leaves — Lining beneath the cover
Banana or palm leaves are described as possible liners that close gaps; they are process materials, not tub construction.
