One day in ancient Japan a small man by the name of Mr Takeshi was in the rice fields of Tokyo getting food for his family. His family was quite poor and he had six children to feed and they lived in a small, cheap, wooden house. As he was collecting the rice grains in his basket, a swarm of bumble bees flew over into the rice fields that he was working in.
They flew in and out of the rice field covering all of the rice grains in honey. Then the bees flew off never to be seen again. Now Mr Takeshi couldn't get food for his family because the rice was too sticky and too sweet like honey.
Weeks passed and the rice was still covered in honey. Then one night a mystical, blue, sparkly rain washed over the rice fields removing the sweetness and goldenness of the honey leaving the rice a sticky, gluey bland grain. The next day as Mr Takeshi returned to the rice field , he found that the rice wasn't sweet anymore, but it was still sticky.
Mr Takeshi decided to harvest the rice anyway to feed his family. It was later added to sushi because normal rice didn't stick to the nori or the fish so well. It was also eaten alone or with another dish. So in the end all of the farmers wanted to harvest in Mr Takeshi's rice field, and that is how sticky rice came to be.
