Fed up with what it considers deteriorating moral standards among young beachgoers, the city of Zushi, Kanagawa Prefecture, is scrambling to purge its popular beach of disorderly and intimidating visitors, typically out-of-control drunks and people with tattoos associated with yakuza.

The city will submit a proposal to a local council as early as next week calling for tighter rules regarding beach attire and demeanor, Zushi municipal official Masashi Koizumi said Wednesday.

If approved, concerts or playing music through loudspeakers will be banned, although acoustic instruments, such as guitars and harmonicas, will be exempted. Barbecuing and consuming alcohol along the shore are also subject to prohibition, as is exposing highly ornamental tattoos, considered synonymous with the yakuza.
