Kumamon seems to have visited Singapore to promote Japonica rice grown in Kumamoto, Japan.
Singapore, which is one of the richest country where Indica rice is more popular than Japonica one, could be an attractive place to sell Japonica rice at higher price.
But, Singaporeans have to be take care of how to cook Japonica rice
When a lot of Indica rice was imported to Japan due to decreasing output of grocery caused by irregular climate, most of the Japan's citizens didn't know how to cook Indica rice, and then, it was dismissed as nasty rice.
So, promoters should inform Singaporeans of the way to cook Japonica rice properly not to repeat the same tragedy.
