Styphnolobium japonicum (L.) Schott , the Pagoda Tree (Chinese Scholar, Japanese pagodatree; syn. Sophora japonica) is a species of small tree or shrub in the subfamily Faboideae of the pea family Fabaceae, formerly included within a broader interpretation of the genus Sophora. The species of Styphnolobium differ from Sophora in lacking the ability to form symbioses with rhizobia (nitrogen fixing bacteria) on their roots. It also differs from the related genus Calia (mescalbeans) in having deciduous leaves and flowers in axillary, not terminal, racemes. The leaves are pinnate, with 9-21 leaflets, and the flowers in pendulous racemes similar to those of the Black locust.

Styphnolobium japonicum is native to eastern Asia (mainly China; despite the name, it is introduced in Japan), is a popular ornamental tree in Europe, North America and South Africa, grown for its white flowers, borne in late summer after most other flowering trees have long finished flowering. It grows into a lofty tree 10-20 m tall with an equal spread, and produces a fine, dark brown timber.
