I've spent many years in northeast Asia too, and will tell you what I've done.
For years, I watched games on the bootleg streaming services like crackstreams.me. For the past couple of seasons, I've been watching college football and college basketball games on YouTube.
YouTube works better for most games. It's a smoother stream with less lag. If it's a major game, however, it's better to watch on a site devoted to piracy because YouTube shuts down the showings of playoff games, championship games, or even big regular season games like the upcoming Texas vs. Ohio State game every few minutes. On YouTube, an important thing to do is leave the game in the search bar: "Texas Ohio State football" with the filter set to "Today". Each time it gets shut down, people load it back on VERY fast. It's always YouTubers with Vietnamese names. You'll see what I mean when you start watching these. Most games, even a good game like Oklahoma vs. Tennessee probably won't get shut down and will stream smoothly for the full length of the game. ETSU vs. Tennessee almost certainly won't get shut down. But I was having to refresh the search bar every minute or two during a Bama/Georgia game a few years ago.
Crackstreams, from my experience, is one of the most dependable of the outright piracy sites. Sportsurge dot net has a lot of streaming sites compiled for each game.
As you know, Japan is 13 hours ahead of us right now and 14 hours after daylight savings time ends, so the games often happen in the middle of the night. Luckily, my bosses have been really cool for letting me go into my workplace so I can watch one game on my laptop and one on the desktop there in the office. I sometimes have a third one on my phone. The way I sell the idea is that my father is hard of hearing, which is no lie, and I don't want my neighbors to hear me yelling to him when the game starts at 2:15 a.m. Keep in mind that it's sometimes better to watch Tennessee games alone and just watch the Bama vs. Vandy type games with relatives and friends on FaceTime since your stream is going to be behind theirs, especially if you're watching on a non-YouTube stream, and people are bad for giving spoilers, more so during games they're emotionally attached to.
