If you want a time capsule of Tokyo’s late-2010s building boom, you could do worse than “Georama Boy, Panorama Girl.” Everything in the film seems to be under construction: the city is a patchwork of scaffolding, temporary fencing and cranes rising over the skeletons of half-finished buildings.

The movie’s characters are also a work in progress, poised on the threshold of adulthood and trying to figure out who they want to be.

Gangly, bespectacled Kenichi (Jin Suzuki) is a diligent student until, just before the university entrance exams, he suddenly announces he’s done with school. After dropping out in spectacular style, he starts loafing around in Shibuya, toting a skateboard in an effort to look cool.
