Happiness Tree

Chance upon a fruiting tree while having my cycling trip. After checking with my friend, was told this is a Happiness Tree.

The fruit is in green colour when it is not ripe.

This fruit started to turn orange in colour.

From far this fruit really looks like oranges.

The shape looks like a persimmon too.

After searching online and I am still not sure why this tree is called Happiness Tree.

When cut opened the fruit, is really look like persimmon.

There is only one seed in this fruit. 

This tree also known as Fuguki tree (Garcinia subelliptica). There are a lot of heritage trees in Ryukyu Islands of  Japan planted some 300 years ago. This species has gained popularity as an ornamental tree for landscaping roadsides and gardens. It must also be an important food source for mammals and insects.
