I grow Japanese cucumbers in my organic community garden. When I first came to the USA, I was surprised how thick American cukes are, and I always take seeds out because they're so seedy! Japanese cukes, on the other hand, are typically skinnier and do not have as many seeds. 

That is unless you thought it can grow slightly bigger and next day when you go, they are about the size of my forearm and I have to cut them and deseed them :-D But I love love love love cukes! It gives me a feeling of Summer and cooler feeling. I made quick pickles (when I say pickles, it's often either salt or dashi pickled, not vinegar pickles since I am not a big fan of all things sour). 

I just roll cukes in green shiso leaves, which also grow in my garden.
