You're the author of this video? This is probably a bit of a spoiler, but fuck it. At the end of the 10th episode, they're at Miyagi's old house (the green one behind the old train tracks that Daniel-San did work on for his training). Has that house remained there since the filming of the movies, or was it demolished afterward, and the production rebuilt it for this series (assuming it's publicly accessible and not on a studio lot)? It'd be interesting to hear from a local.
Normally I don't watch modern day movies and TV series given most of them are crap (especially re-boots of old series and movies), but I'm a fan of the movie franchise, so the nostalgia hooked me in. While I was skeptical, I have to say this is actually pretty good overall. While there is a bit of PC/SJW/Diversity shit in there, the Johnny character counteracts a lot of it with how anti-pc he is in this, and I think it's pretty refreshing to see that in this day and age (especially from a straight white man, no less); I legitimately laughed out loud at some of the lines he had in this. I also like how this series has him as the central character and focuses more on his story and why he's the way he is, and you get to empathise with him as opposed to just seeing him as "the bad guy" like you did in the movies. While you could see where the plot was going as you were watching it, there is a bit of depth to most of the characters and the relationships to one another, and I think the writing deserves some credit for that. The last 5 minutes of the last episode has set up possibly another season. Time will tell.
