An issue with the "Hinomaru" and national anthem was raised once again when Tokyo hosted the 1964 Summer Olympic Games. Before the Olympic Games, the size of the sun disc of the national flag was changed partly because the sun disc was not considered striking when it was being flown with other national flags. Tadamasa Fukiura, a color specialist, chose to set the sun disc at two thirds of the flag's length. Fukiura also chose the flag colors for the 1964 as well as the 1998 Winter Olympics in Nagano.
