I think "proper" superblocks in Tokyo tend to suffer from similar issues as in other cities. You end up building these huge buildings and it all feels a bit claustrophobic But almost all the roads in Tokyo have the big superblock advantage: pedestrian first. While there's a bunch of big avenues, basically no smaller roads have sidewalks. Instead people just walk "on the road" and cars drive slowly. Lots of roads are basically "1.5 cars" wide too. This helps with making denser communities without needing huge appartement buildings. Loads of areas of Tokyo are "just " 2-4 story buildings. But work of small details mean you can end up being pretty dense anyways.
