I ordered a pack of Japanese Long Cucumber seeds from Baker Creek, and planted them along an 8' long x 5' high cattle panel. I want to recommend these - they're great!
I looked around online, and I think these may be a variety called "Suhyo" which is very popular in Japan. I don't know that for sure.
These cukes are very productive, and enormous. The flesh is light green and has a great flavor. They stay crisp and dense even when they're 18-22" long, the seeds are few and small, and the skin is thin and easy to peel. The vines are compact and they've stayed on that 5' fence without trying to spread across my garden paths.
We've been eating these for a couple of weeks, and they show no sign of slowing down. There are still lots of blooms and little cucumbers setting on, and the vines are vigorous and green. The only negative I've found about them is that I'll soon be supplying everybody I know with cukes because they're producing 'way more than we need. I'll be making a whole bunch of pickles tomorrow.
I picked these only two days ago, and here's what I picked again this afternoon.
