Sugoi koto @Shuichi!
Instead of Century Gothic I recommend a more modern slab serif font like Museo and the letter spacing is too big, a 33% smaller spacing looks way better.
Also the pin should be set on the 2nd 'o' so it will be centered to give balance to the logo and also because it will give an emphasis to "coco" (which I presume is derived from the Japanese "koko" which means "here") and visually separates it from "iru" which means "to be/ to exist".
I hope you like my proposal.
