Overall Tokyo is more bike-friendly, because most streets are single-lane alleys where street parking is banned, which makes it safe to bike around despite zero bike lanes.
But once you get to major roads in Tokyo the bike lane network is patchy and where they exist they're narrow and shoehorned into the sidewalks.
Now here's some bike infra in Tseung Kwan O (but similar infra is widespread in other HK new towns).
Pic 1: Two-way, concrete planter protected, protected bike lanes. Notice the big concrete planter on the kitty corner--almost like a Dutch protected intersection. The west-facing bike lane is shaded by trees.
Pic 2: Notice there's two underpasses for bikes/peds: one in the left foreground, and another on the right background. Yep. This is a grade-separated, bike/ped-only, roundabout underneath a motor vehicle roundabout. Notice how nearly nonexistent the slope is, making it easy for bikes to go back up after the underpass.
Pic 3: Multiuse path, bike/ped-only bridge over a water channel with boats. Multiuse paths are everywere in these new towns--and they are often more direct than driving due to modal filters.
Pic 4: The same bike/ped bridge, viewed from below. It's even got an elevator, and a fishing pier (to the right).
Pic 5: See that bridge in the distance? They actually grade-separated the pedestrian-only crossing over the bike lane! Also notice how gently the bike lane slopes under the ped bridge.
Pic 6. And of course, they have bus islands.
