Japanese Sign Language (JSL) Resources?

Does anyone have any resources available for comprehensible input in JSL at the beginner level?

I know this isn't really Japanese, but there have been threads made here about JSL in the past. Even so, all resources from the previous threads have been the typical "sign-translation" videos. This is not what I am looking for. I'm looking for something like this or this.

Something like this is ok but not great. There also simply isn't enough of it on the channel.

Such videos exist in most languages, but I can't find any for JSL. I've tried searching in both English and Japanese, but I only get the sign-translation videos, or blogs that are way too high level for a beginner.

Thanks in advanced for any input (pun not intended) or resources.
