大弓

大弓 (daikyū, ōyumi): diagram of a traditional Japanese longbow.

大弓 (ōyumi): an ancient Qin dynasty stonebow.

May have been coined in Japan of Middle Chinese-derived components, as a compound of 大 (dai, “large, great”) +‎ 弓 (kyū, “bow”).

Alternatively, may be a reanalysis of older term 大弓 (ōyumi, see below), applying the on'yomi to the characters.
