Yes, the art of Mitsugo (みつご) is cute — really cute. But it is also a lot more things than just that.
I know that a lot of people (in the USA, at least) have a hard time looking at art objectively when it contains very cute things — especially if it is anime. Influences from Japan have been changing this and you can see “cuteness” becoming more acceptable here like it is in Japan. For instance, look at the cartoon mascots of the new Firefox. I don’t think that sort of childish aesthetic (used in a lot of things nowadays) would have done so well without some influence from Japan. However, I still know that the USA is far from being able to accept art like Mitsugo’s as Japan does. Don’t get me wrong — I am not saying I wish everyone liked this art, and any cute art like it. I am simply saying that if you are downplaying the artistic brilliance of Mitsugo, or any other “cute” artist like them, simply for being cute, you are making a large mistake. If you can imagine the art with something less cute in it, I think you will see why. Whether this is eventually realized by the larger art world or not matters not though — Japan is a pretty big place, and it has its own thriving community of artists all about this.
And for those of you who didn’t need to hear this, I hope you enjoy Mitsugo.
