I actually thought the username makes you easier to recognize in the mass of other channels. But if you really don't want to use it, go with Tokyo Walks Stream or your own name (more freedom in case you do Walks in other places later). I would love a youtube channel and landscape format. I like to cast the videos to our tv and just have it running in the background to remind us of all the nice places we have been. But what really makes it interesting for us is all the extra trivia and info that shows up organically thanks to you answering comments. Good luck! Future subscriber here!
