Japan now has sweet onigiri cakes and they're absolutely delicious soranews24.com

One of Japan’s most well-known foods has to be the humble onigiri rice ball.
Called Omusubi Cake, these sweet little morsels come from the Tsukiichi pattisserie in Osaka.
After a year in development, the Omusubi Cakes made their debut in August this year and quickly became a hit with locals, selling in excess of 60,000 in just a few months.
Starting off with the Grapefruit Omusubi Cake, we lifted the pull tab on the packaging and tore it down the middle, just like we would do on a regular onigiri.
We moved on to try the Green Tea variety, which also looked like a rice ball from the outside.
