I was discouraged from doing this after having someone make such a video that generated millions of views, but no sales at all (https://www.candyjapan.com/behind-the-scenes/sales-results-f...). (Just noticed that video has since been removed for "violating community guidelines", I wonder what's up with that)
But I'm still a bit motivated to make more videos, because at 10k subscribers you get to visit the Roppongi YouTube space :-) Here's the old channel we haven't really updated in a long time: https://www.youtube.com/channel/UCAWrpxBNP8LukXGd4xQIDxg
I wouldn’t discount YouTube based on that experience. That channel looks to be one of the channels that drives a lot of views through children, specifically, children watch and watch and watch these videos on TVs (driving up the viewcounts) but aren’t engaged, they aren’t going to convert to customers. You may wish to try more targeted channels, i.e channels with an engaged audience of people who like Japanese culture. A video with 1,000 views to people who are enamoured with Japanese culture will perform significantly better than that video.
