Last time I asked a question about how could I check if my apartment was VDSL or hikari, because it had a 光コンセント but AU website says it can only support VDSL. I called NTT and they told me that it supports NTT Hikari FLETS (up to 1 gb), but since AU uses their own line I can only get 100 Mbps via VDSL if I choose au. So, after some talk, I was recommended to choose BIGLOBE, but I don’t know if they’re the best option
I’ve seen many people saying FLETS is pretty bad, but apparently anyone can get high and stable speeds even through FLETS if they use Ipv4 over ipv6 because it prevents congestion, is that right?
If so, does anyone have recommendations on routers to use with Hikari FLETS?

I’ve used Flets for many years, and have always had a fantastic connection. I can always download from Steam at around 50MB/s.
I’m in the countryside and using AsahiNet on FLETS and just got ~600Mbps down, so it’s not inherently bad. Just depends on the specific situation.
Please see the wiki: https://www.reddit.com/r/japanlife/wiki/internet
There’s a list of all the domestic makers and routers.
My personal recommendation if you don’t have any specific requirements is the following: https://kakaku.com/item/K0001359587/
It supports wifi6, all IPoE services, and is cheap enough with decent performance.
With ipoe, your provider matters much less as all your traffic goes through a high bandwidth VNE. so you can pick cheapest.
fwiw, biglobe is fine – one of my locations is connected with them. pppoe was awful, enabled ipv6 and it’s great. also if you already have an account with them it will take 2-3 business days to enable ipv6 so do it when applying.
The line matters less than the congestion of your specific living establishment, in my experience. An apartment generally shares a max bandwidth so peak times can get rough, and there is no way to really know until you move in.
Choose a provider that offers a free router and use that. Or choose buffalo.
In my experience, even “bad” flets is going to be better than VDSL. “Bad” *usually* means, instead of 1 Gbit, you get 200 Mbit.
Also, you have to be careful with the provider you’re choosing because they implement ipv6 differently.
You may refer to this article which conveniently tabulates routers from various brands and their supported ipv6 implementations.

Hope this helps.
Flets is not inherently bad. It all depends on how busy the particular segment is that you’re connected to.
At our first place on Okinawa we were the first (and only) subscriber in the local area. My limit was the network hardware in my desktop. At our second place we got a segment shared with lots of apartments, and it was effectively unusable at night. IPv6 did improve it a bit, but only to the point where we could actually use the line.
FLETS is great. Just go with Asahi-net and use IPv6 with IPv4 tunneling. You’ll be getting multiple hundreds of Mbps with low fiber latency.
