This is why you need to consider not to wear the 'Rising Sun' T-shirt. 

Would you ever wear a T-Shirt with a Swastika on it? Assuming that you are a right-minded person with a good sense of decency, you would not. Swastika represents a political regime that committed horrible acts upon many — to the extent that it became the symbol of crime against humanity and ultimately –and rather ironically– contributed to furthering of human rights as an essential political discourse in the post-World War II world. A Swastika is not only offensive to the Jewish people, but to everyone, for it is an insult to the very ideals that we hold sacred — that every human life is deserving of respect. this society that abhors Nazis does not hold the same standard for the images of the Japanese Rising Sun, which, is in a way, even more offensive than Swastikas. The Rising Sun flag was the symbol of the Empire of Japan during late 19th and early 20th centuries. It is extremely easy to find images of the Rising Sun — on t-shirts, restaurants, films, TV, et cetera. In a way, we cannot blame the people who use this image. Everyone knows that Adolf Hitler and his administration committed atrocities against humanity. But comfort women, maruta, and the Rape of Nanking aren’t concepts that are taught in Edmonton Public Schools — at least with the same degree of importance as that of Holocaust.

The Empire of Japan operated with the similar ideologies that prompted the invasion of Czechoslovakia and the Final Solution. Japan had industrialized much earlier than the rest of Asia, and developed a formidable military force with the goal of forming a grand empire. Behind this goal, there was the belief that the Japanese were racially superior to other Asian ethnic groups, as their society had moved “beyond Asia” much earlier than others. Thus, the Japanese administration was not hesitant to treating people from other Asian countries, such as Korea, China, and Philippines, as the Nazi Germany treated the Jewish.
