In order to vote: click the big red button in the middle of the screen. A new window should pop up. In the blank field type 関ジャニ∞ (or copy/paste from here). In the next place, it asks you to choose your age group. The last one with the radial buttons is your gender; male is on the left, and female is on the right. Then on the bottom choose the button on the left to submit your vote. Let’s all support Eito!
Edit: agtoro and makuhita just pointed out to me that you can vote as many times as you want. So let's vote over and over again and bring Eito to Yokohama Arena! Big thank you to everyone who has already done so<3
