Pacific Theater of Operations (P.T.O.) (Teitoku no Ketsudan) is a console strategy game released by Koei in 1993. It was available for play on the Sega Genesis and Super Nintendo (SNES) platforms. Players could assume one side of the Pacific Theater of Operations during World War II, acting as naval commander, organizing fleets, building new ships, appropriating supplies and fuel, and even engaging in diplomacy with other countries. The player can choose one of several World War Two battles to simulate, or could control the entire Pacific campaign well before the Attack on Pearl Harbor.
A sequel, P.T.O. II, was released by Koei in 1995. The next version to be released in America was P.T.O. IV for the Playstation 2, in 2002.

Other countries will behave as they did historically; for example, Italy will cease being a member of the Axis in 1944, due to Allied invasion. The countries available as allies are:
Each power has one home port, to which newly-manufactured ships and aircraft are stationed upon completion. During the turn, aircraft, fuel, and materials can be assigned to any base; however, depending on the safety and distance of the trade route, some resources may not arrive. Certain ports are capable of 'Urgent Repair', meaning they can effect some small repairs to ships docked there. As not all ports have this capability, control of these key regions is crucial in order to maintain the fighting capabilities of one's fleet at sea with less turnaround time for ship repair when ships are damaged in combat.
There are several types of warship available: dreadnought battleships, battleships, cruisers, fleet aircraft carriers, light carriers, destroyers, and submarines. Each power starts out with a certain number of ships of each type, and a number of ships under construction, usually launching around their historical commission date. Additional ships can be constructed, but only to replace ships previously lost in battle, either by the player or prior to the scenario's start date. Ship construction can be scheduled for 6-24 months out; the closer the launch date, the more industrial power will be expended during construction. Materials are consumed as well, dependent on the type of hull being built, and the ship ratings chosen during design. The ship class chosen during construction is cosmetic only; it does not effect actual ship limitations or attributes like the actual hull type does.
Ships are organized into fleets, which can comprise up to 16 ships. Up to 16 fleets can be arranged from inactive ships at the home port. Only one fleet from each side can engage in a battle at any one time, so fleets must attack an enemy in succession rather than at once. Fleets have a rating for Morale and Fatigue, betweeon 0 and 99; morale goes up after victories or during shore leave, and down during defeats or when a flagship is lost. It can also be raised by an emergency banquet at sea. Fatigue goes up after every battle, and when the crew is infected by plague.
Ships also have individual levels of crew experience; this value starts high for the Japanese, and low for the US. Experience levels gradually increase through combat, or by conducting training drills.
Another type of ship that can be constructed is transports. These are used for carrying additional fuel to extend fleet range, and for transporting resources from territories to home ports.
Additional, non-controlled shipping fleets are constantly active in the game, though not displayed on the tactical maps. Transport fleets supplying bases can be protected by unlisted destroyers and cruisers, but will not engage an enemy fleet.
Aircraft can be deployed to bases or to aircraft carriers, although some ship types allow scouts to be launched via catapult. Aircraft placed at bases take a defensive role against attacking fleet(s) or aircraft, and are used to scout for enemy fleets during the day. After enemy fleets are found, the land-based aircraft will then sortie to attack.
