Kantai Collection, also known as KanColle, is a Japanese free-to-play web browser game developed by Kadokawa Games and published by DMM.com. The game's core concept involves personifying World War II warships as young women, with their personalities and characteristics reflecting the historical vessels. Initially featuring only Japanese ships, the game has expanded to include vessels from other nations like Germany and America. Gameplay encompasses various aspects of naval warfare, including combat, ship maintenance, repair, upgrades, logistics, and strategic planning.

The game was launched in April 2013 and is primarily available in Japan. It has evolved into a significant media franchise, spawning multiple manga series, light novels, and an anime television series. Players assume the role of an admiral, assembling fleets of "ship girls" represented as cards. Progression involves advancing through maps, gaining experience, acquiring new ship girls, and managing resources like fuel, ammunition, steel, and bauxite. Customization of ships through equipment and strategic decisions are key elements, with a significant RNG component influencing battles and acquisition.

In Kantai Collection, players act as admirals, forming squadrons of "ship girls"—characters representing World War II warships. These girls are presented as cards with distinct attributes, and the player's objective is to lead these fleets in strategic naval battles. While combat is largely automated, player involvement is crucial for micromanagement tasks such as building, repairing, and upgrading ships. The game involves progressing through various maps, earning experience points, and acquiring new ship girls through drops or crafting, which often involves a degree of randomization. Resource management is essential, with players needing fuel, ammunition, steel, and bauxite to construct, resupply, and repair their fleets. Ships can be customized with various equipment, enhancing their combat effectiveness. Ship girls gain experience and level up, with the option to remodel them into more advanced forms. Modernization allows players to enhance one ship's stats by sacrificing another. Fatigue affects ship performance, which can be alleviated by rest or by improving fleet morale. Damaged ships visually degrade, and if a ship's durability reaches zero, it is considered sunk and lost unless an emergency repair item is available.

The central figures in Kantai Collection are the "ship girls" (kanmusu), who are moe anthropomorphisms of historical World War II warships. These characters are designed to reflect the attributes and history of the vessels they represent. For instance, larger warships like battleships and aircraft carriers are typically depicted as young women, while smaller vessels such as destroyers are often portrayed as younger girls. Their personalities and dialogue can also reference their ship's origins; for example, a ship named after a vessel with British connections might incorporate English phrases into its speech. Characters from the same ship class or type may share similar visual traits or attire. Initially, the game featured 94 Imperial Japanese Navy ships, but this number has significantly increased over time, incorporating vessels from various other navies including those of Germany, the United States, and the Soviet Union. Each ship girl is illustrated by a specific artist, contributing to the diverse visual style of the game's cast.

Launched in April 2013, Kantai Collection quickly became a popular web browser game in Japan, attracting millions of registered players. Its success led to its expansion into a broader media franchise, encompassing multiple manga series, light novels, a tabletop role-playing game, a PlayStation Vita adaptation, and several anime television series and films. The game operates on a free-to-play model, but offers optional microtransactions for premium bonuses, such as expanded repair docks or increased ship storage capacity. A unique monetization feature allows players to purchase "marriage papers and rings" to effectively "marry" a ship girl, which breaks the level cap and provides stat bonuses. The game is primarily intended for a Japanese audience, with its interface exclusively in Japanese. Access outside Japan typically requires a VPN, though this may violate the terms of service. Due to its immense popularity, new player registrations have sometimes been managed through lotteries to prevent server overload.
