It would have sugar if it was part of a rice cake no doubt other wise I don't see any sugar being added.If it had a sugary taste it was most likely Glutinous rice which is grown all over Asia this rice has sweet taste to it naturally.

Japanese rice is not the same as Glutinous rice but also has a sticky texture but not the same taste as Glutinous rice.I would not surprised if many places used Glutinous rice and hope that no one noticed.Another dark secret many places outside of Japan that serve "Wasabi" are really serving you horseradish sauce(not made from Wasabi) that has been colored to have the green color of Wasabi.

By the way the specific type of rice cake I mentioned earlier are called Daifuku.I can eat my weight in them easily they can be filled with just about anything fruits and bean paste usually.
