Osaka 69 is a good japanese porn tube, with top quality self-hosted videos taken from the best japanese porn studios. An easy and convenient UI does mean that there are a lot of features you’ll be missing out on here, but the basics and a search engine will still get you where you want to be. There’s a decent number of categories and an even larger number of videos, and frankly the dark design and UI is very easy on the eyes. Unfortunately the site does seem to have stopped updating at the moment, but it has so much hd quality videos to satisfy your need of japan porn for long time ahead!
