How did Caesar go to Japan to attend the Summer Sonik Music Festival? How many days?

The corresponding route of Caesar's tourism. Excerpt from Caesar's trip to official website:

On the first day in Tokyo, I checked into a hotel.

The next day and the third day were at the music festival. With a world-class big-name music team, you will see the largest bands in the world, such as Metallica, Linkin Park, Green Day and Suede, and you will see the newest and hottest bands in the world, such as My Chemical Romance, Bullet for My Valentine, Yellow Card and New found glory. You will see their top bands in Japan, such as ellegarden and Asian ku-fung gen generation. Besides, you can also see the pure sea where the Japanese are keen on environmental protection, fireworks and special foods gathered from all over Japan.

On the fourth day, I went shopping in famous prosperous and fashionable places such as Shinjuku, Harajuku, Ginza and Akihabara. Girls will be picky about all kinds of clothes, while men will be fascinated by all kinds of animation games and electrical appliances.

Go back to Beijing on the fifth day, that's all.
