What's the source for this old Japanese schoolgirls kissing video?

A few years ago, I stumbled upon this clip on xhamster.com and have tried to locate the source of it since, but to no avail. Even with the addition of reverse image search on Google, it only linked me to the same clip on various different websites. Looking up jav websites in other to track down any potential leads has also been fruitless due to how many lesbian japanese schoolgirls content exists, and from the looks of it, this particular scene seems to be on the older side even taking the not so-good quality into account. It might be from the 2000s, I'm not sure, but it does make it all the more difficult to find from my end. I'd appreciate some much needed help on this!
