The International Olympic Committee (IOC) registered “五輪” (5 rings) in total of 22 categories including chemicals, cosmetics, programs, incinerators and bicycles etc.

Since in Japan “五輪” is well-known as a word expressing the Olympic Games, people who have misused it have been subject to penalties under Unfair Competition Prevention Act.

Now IOC is able to warn in a more comprehendible manner for those who misuse it.

Even if you are joking, you would be better not to use ”五輪” in the name of your product or service.
Please take care.
