Hovenia dulcis

Hovenia dulcis, the Japanese raisin tree or oriental raisin tree, is a hardy tree found from Asia, over Eastern China (萬壽果) and Korea (헛개나무) to the Himalayas (up to altitudes of 2,000 m), growing preferably in a sunny position on moist sandy or loamy soils. The tree has been introduced as an ornamental tree to several countries, and the fruit is also edible. It is considered being one of the most pervasive invader in Brazilian subtropical forests.
