I was curious so I went and google translated the Youtube comments because I really want to see if 13th gen is hitting with the Japanese Wota too. (Google translate has gotten better as an aside) Here's a ton of the comments:
1. Eripon. Lots of talk about how good Eripon did and how surprised they were.
2. Yokoyama was also surprising to people about how well she did despite only being in KSS for a few months. Overall, she seems to be making a bigger impact than Kaede, but that could be because Kaede already has a fanbase and Reina started from Zero.
3. SURPRISINGLY there was talk about MIKI being an ace. Maybe I'm off about how popular she is in Japan? I always thought she wasn't that popular.
4. Lots of talk about how people loved Harunan's and Miki's duo line (Sorry CaptainBerryzGiraffe

)
5. Kaede's dancing is highly praised (One guy even mentioned the exact part I did!)
6. Sakura talk is everywhere. Man, when did she get popular with the Wota? That snuck right past me.
7. Lots of talk about 13th gens impact and how this seems like a battle song. A lot of people are super impressed with how good 13th gen are right out the gate.
Overall the impact is just as strong there as it is here.
