Suzuka usually is a fairly static race the past 15 years or so, though there are occasions when we do see passing usually from different tire strategies creating offsets (I recall a recent one where there was a bunch of passing entering Spoon - which is not a normal passing location there). But those are exceptions now.
If the new formula next year doesn't improve things on that front, more tracks will have to look to configuration changes to keep things interesting. For Suzuka, one might be to make R130 a much sharper corner to force it into being a braking zone & create passing opportunities there. If DRS were being kept, that would have also allowed the longer back straight to be a DRS zone.
Fast & medium speed corners used to be a real test of car performance & driver skill, and a lot of older tracks featured them, But now an F1 car can take formerly risky turns like R130 or Pouhon at Spa flat out while the driver's on the phone ordering a pizza. Now the tracks were there are a lot of passing are basically just: long straight, 90-degree turn, other long straight, 90-degree turn., etc. Ironically, Vegas - a track everyone expected would suck - turned out to be an entertaining venue because of that.
