Jusowhy, also presented as 주소와이, is a Korean-language link directory that brings a wide range of website addresses together on one page. It organizes links into categories so visitors can browse listings for adult content, entertainment and nightlife, sports betting and casinos, gambling-site verification, webtoons, television, live sports, torrents, online communities, adult products, and Korean communities abroad. The site says it checks popular rankings by category and updates links to reflect addresses that are currently accessible, with checks performed daily.

Users can save frequently visited links to a favorites list, and the site provides options to register links, contact the operator about listings, and inquire about banner advertising. It also features notices, login and membership registration, and links to official channels. Jusowhy functions primarily as a directory and discovery service, connecting users with external websites rather than presenting itself as the provider of all the listed content or services.

Its broad category structure is intended to help visitors find and revisit relevant destinations more conveniently
