The Tsugaru apple does not have any specific physical characteristics that make it distinguishable. It kind of looks like a Fuji.
The texture and consistency is best described as barely enough to be considered crunchy. Like, I would almost call it mushy. Soft, but somehow hard enough to give a crunch. As for taste, it is really bland. It has a Fuji-like edge after some chewing, but asides from that nothing else.
I was quite disappointed with the Tsugaru apple.
