Because they were idiots
It should not be important about learning the song Tang. The history of China in important to learn.
Because this whole nation has been influenced by China since they sent their missions to Tang dynasty. They introduced Chinese and Buddhist philosophy to Japan; they studied Chinese language and writings and combined them with their own language; Japanese architectures (include the palaces) were just copies of Tang's architectures (not the ones you see in today's China, they are mostly from Ming and Qing dynasty); some technology and crafts were also brought to Japan... so many things. If you have been to Japan, Korea, and Vietnam, and you know Eastern Asian culture well, you would realized that they have so many similarities. Today, Chinese characters are still used in formals, and the way Japanese call their government deparments and local governments are actually same as Tang dynasty's.
