Sorry for being late to follow up on this. I ended up switching providers to Asahi Net and immediately saw an improvement in speed and reliability. This made the most significant difference, even more than the upgrade to 1 Gbps Hikari.

Asahi Net automatically sort out all the IPv6 stuff with NTT for new customers. So after a couple of weeks users can just activate 'IPv4 over IPv6' on their 'My page' portal. Actually using IPv4 over IPv6 requires a router that supports DS-Lite. Asahi Net officially support a few routers by Buffalo, Elecom, i-o data, and NEC[1]. But in principle any DS-Lite-capable router should work. Among international brands, TP-Link[2] sell routers that support DS-Lite and similar standards (these vary by provider).

I've been using IPv4 over IPv6 for about a week now and haven't had any issues. It's solid and speeds are good, but this was true on Asahi Net's standard IPv4 connection as well, so it's not a very noticeable difference. Actually changing to IPv4 over IPv6 was painless, just a simple configuration change on the router. I had to reconnect and my IP changed, but other than that there was no interruption. Users can also change back to standard IPv4 (PPPoE) any time[3].
