Kakko (instrument)
Japanese drum used in gagaku music

The kakko (羯鼓/鞨鼓) is a Japanese double-headed drum. Kakko drums are usually laid sideways on stands, and are played on both drumheads with sticks known as bachi. Kakko drums have been used in taiko ensembles, but are also used in the gagaku form of older Japanese court music.
History
The kakko is derived from the Chinese jiegu, a drum popular in China during the Tang dynasty; the Korean galgo is also derived from this drum.
Construction
One way in which the kakko differs from the regular taiko drum is in the way in which it is made taut. Like the shime-daiko and tsuzumi, the skin of the heads are first stretched over metal hoops before they are placed on the body, tying them to each other and tightening them making them taut.
This brief starts where responsible research should: with the source description of “Kakko (instrument)” as japanese drum used in gagaku music. Everything that follows is an evidence route, not borrowed authority.
Why this record matters
The subject matters to the general reference register because the source frames it as japanese drum used in gagaku music. Its deeper value depends on whether names, dates, institutions and citations support that framing.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated May 22, 2026. The linked authority identifier is Q15614634. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
