This application allows you to listen to a total of about 500 chants, ranging from those of the J-League (J1, J2, and J3) teams that everyone knows, such as the Urawa Reds and Yokohama F Marinos, to those of the JFL and regional league clubs fighting to join the J-League. All songs come with lyrics cards, so you can easily memorize chants you have never heard before. It also has a cheering chat function, which you can use to let your emotions explode when a player scores a goal and you want to shout, or when the team you are cheering for wins a game. We will continue to add more and more fun features in the future.
