How popular is Do As Infinity in Japan?

[Tsureboru]

Hello, I've been wondering for some time now about the popularity of the J-rock/J-pop band Do As Infinity. They are my favorite artist and I listen to them everyday. Its almost a ritual for me. Can't get enough of them! :clap:

They are very popular. Every single reaches at least top 5 in the Oricon chart and so do their albums, however that also depends on what else goes on sale that week.
