I don't know why they decided to do the concert all the way in Fujikyu.
Myself with my friend Jenni before the concert started.
Though..it was very cool seeing Nao playing the drums with water splashing everywhere. I had a amazing time, the sound was great for being a outdoor concert. I believe all the merch sold out, well most people I saw bought like 5 of everything lol *cough* my friends bought LOTS.
