I don't know which is correct. And if you're Googling this artist's name, you may not either. So no matter which way you spelled it, you got here didn't you?
I do know the first name is Kenji. And since Van Gogh's Ear Cafe in Union, NJ wasn't completely sure, they kept things on a first name basis at their web site.
Now the Google searches I performed didn't come up with a home page, but they came up with a few Kenji Hasegawas. Unless the DJ and the artist are one in the same (which is entirely possible).
I did come up something at KidRobot though. Nice Munny, Kenji.
I was at Van Gogh's Ear last week when I helped my niece move into her new apartment. Unfortunately, I neglected to grab Kenji's business card. My camera phone was full, and deleting the kids was not an option, so I don't have a pic of his “gasmask” painting. There were a few I really liked. I love the collage feel, and the occasional graffiti fluorishes. His work definitely would have a place at Juxtapoz.
Maybe I'll make it over there again, and see if the work is up for sale.
