−'''''Acer shirasawanum''''' ('''Shirasawa's Maple''' or '''Fullmoon Maple''') is a species of [[maple]] native to [[Japan]], on central and southern [[Honshū]] ([[Fukushima Prefecture]] southwards), [[Shikoku]], and [[Kyūshū]].<ref name=osu>Okayama science university: [http://had0.big.ous.ac.jp/plantsdic/angiospermae/dicotyledoneae/choripetalae/aceraceae/ooitayameigetsu/ooitayameigetsu.htm ''Acer shirasawanum''] (in Japanese; [http://translate.google.com/translate?hl=en&sl=ja&u=http://had0.big.ous.ac.jp/plantsdic/angiospermae/dicotyledoneae/choripetalae/aceraceae/ooitayameigetsu/ooitayameigetsu.htm&sa=X&oi=translate& google translation])</ref>
−It is a [[deciduous]] large [[shrub]] or small [[tree]] growing to 8–15 m tall with a [[trunk (botany)|trunk]] up to 50 cm diameter. The [[bark]] is smooth on both young and old trees. The shoots are slender, and hairless. The [[leaf|leaves]] are rounded, 4.5–8 cm long and 6–12 cm broad, palmately veined and lobed, with 9–13 (rarely 7) serrate shallowly incised lobes; they are hairless, or thinly hairy at first with white hairs; the petiole is 3–7 cm long and hairless. In autumn, the leaves turn bright gold or orange to dark red. The [[flower]]s are 1 cm diameter, with five dark purplish-red sepals, five small whitish petals (soon lost), and red stamens; they are [[plant sexuality|andromonoecious]], with inflorescences containing flowers with either both sexes, or just male, and are produced 10–20 together in erect terminal [[corymb]]s in early spring soon after the leaves appear. The [[fruit]] is a paired [[samara (fruit)|samara]] with the nutlets 5–10 mm diameter with a 20–25 mm wing, erect above the leaves, bright red maturing brown.<ref name=osu/><ref name=osu1>Okayama science university: [http://had0.big.ous.ac.jp/plantsdic/angiospermae/dicotyledoneae/choripetalae/aceraceae/ooitayameigetsu/ooitayameigetsu2.htm ''Acer shirasawanum'' flowers] (in Japanese; [http://translate.google.com/translate?hl=en&sl=ja&u=http://had0.big.ous.ac.jp/plantsdic/angiospermae/dicotyledoneae/choripetalae/aceraceae/ooitayameigetsu/ooitayameigetsu2.htm&sa=X&oi=translate& google translation])</ref><ref name=rushforth>Rushforth, K.

−It can be distinguished from its close relatives ''[[Acer japonicum]]'' (ハウチワカエデ ''hauchiwakaede'') and ''[[Acer sieboldianum]]'' (コハウチワカエデ ''kohauchiwakaede'') by its hairless shoots; from ''A. sieboldianum'' also by its red, not yellow, flowers.<ref name=kanagawa>Kanagawa Prefecture trees and shrubs: [http://www.geocities.jp/greensv88/jumoku-zz-kohauchiwakaede.htm ''Acer sieboldianum''] (in Japanese; [http://translate.google.com/translate?hl=en&sl=ja&u=http://www.geocities.jp/greensv88/jumoku-zz-kohauchiwakaede.htm&sa=X&oi=translate& google translation]).

−Some authorities, especially in [[horticulture]], still use the older classification including the species in ''A. japonicum''; many specimens in cultivation also remain mislabelled as ''A. japonicum''.<ref name="gelderen">''Maples for Gardens: A Color Encyclopedia'' by C.J. van Gelderen & D.M. van Gelderen, 1999</ref>

−It is grown as an [[ornamental tree]] in [[gardens]] for its foliage and fall colour, but is seen far less commonly than ''[[Acer palmatum]]'' (Japanese Maple). A number of [[cultivar]]s have been selected; the lighter-coloured ''A. shirasawanum'' cultivar 'Aureum' is very widely grown, much more common in cultivation than the main species; it is [[plant propagation|propagated]] by [[grafting]] onto more hardy and fast-growing ''Acer'' species, in particular ''A. palmatum'' and ''A. japonicum''.<ref name="gelderen"/>
