I drew random cherry blossoms and felt it looked like it needed some random Japanese thrown in to complete the picture, but I didn’t want to just write 桜. I wanted to do something snarky like this T-shirt. But I have restricted internet access and couldn’t look it up at work. 
Sadly, this was the only complete sentence I could come up with off the top of my head. Other than maybe “日本語がわかりません.” I need to study more.
