'''''Ilex crenata''''' ('''Japanese Holly''' or '''Box-leaved Holly'''; [[Japanese language|Japanese]]: イヌツゲ ''inutsuge'') is a species of [[holly]] native to eastern [[China]], [[Japan]], [[Korea]], [[Taiwan]], and [[Sakhalin]].<ref name=grin>Germplasm Resources Information Network: [http://www.ars-grin.gov/cgi-bin/npgs/html/taxon.pl?19691 ''Ilex crenata'']</ref>
Japanese Holly is grown as an [[ornamental plant]] for its dense evergreen foliage. It is superficially similar in appearance to [[Buxus|box]] (''Buxus''), and is often used in similar situations; it can readily be distinguished from box by its alternate, not opposite, leaf arrangement.
It is an [[evergreen]] [[shrub]] or small [[tree]] growing to a height of 3-5 m (rarely 10 m) tall, with a trunk diameter up to 20 cm. The [[leaf|leaves]] are glossy dark green, small, 10-30 mm long and 10-17 mm broad, with a crenate margin, sometimes spiny. The [[flower]]s are [[plant sexuality|dioecious]], white, four-lobed. The [[fruit]] is a black [[drupe]] 5 mm diameter, containing four [[seed]]s. It grows well in acidic soil, between a [[pH]] of 3.7 and 6.0.<ref name=oht>Osaka hundred trees: [http://www.ne.jp/asahi/osaka/100ju/Inutuge.htm ''Ilex crenata''] (in Japanese; [http://translate.google.com/translate?hl=en&sl=ja&u=http://www.ne.jp/asahi/osaka/100ju/Inutuge.htm&sa=X&oi=translate& google translation])</ref><ref name=osu>Okayama Science University: [http://had0.big.ous.ac.jp/~hada/plantsdic/angiospermae/dicotyledoneae/choripetalae/aquifoliaceae/inutsuge/inutsuge.htm ''Ilex crenata''] (in Japanese; [http://translate.google.com/translate?hl=en&sl=ja&u=http://had0.big.ous.ac.jp/~hada/plantsdic/angiospermae/dicotyledoneae/choripetalae/aquifoliaceae/inutsuge/inutsuge.htm&sa=X&oi=translate& google translation])</ref><ref name=rhs>Huxley, A., ed.
