The Star Trek: The Invasion of Klingon Empire is one of Tsukuda Hobby's SF Series games (item no. HG-009-4000, the last four digits indicating the price in Japanese yen). Produced in by the Japanese toy/game maker, and only released in Japan, it bears the additional subtitle "The Game of Space War in Star Trek".
This is a strategic hex- and counter-based ship-to-ship combat game (in the same vein as FASA's later Star Trek II: Starship Combat Simulator game and, most conspicuously, Task Force Games' prior Star Fleet Battles games), given the four-part mounted map showing the United Federation of Planets, the Klingon Empire (or a portion thereof), the Romulan Empire (ditto), and a large amount of space between these. Production is clearly important, as there seem to be many rules sections covering Ship Factories. In the same vein, the ship designs (especially the Federation vessels) seem inspired by those in Star Fleet Battles (which were, in turn, inspired by those in Franz Joseph's Star Trek Star Fleet Technical Manual). The actual ship combat looks to take place on a smaller board, where the movement of ship squadrons takes place on the larger board.
The game definitely appears to have two sides, the Federation and the Klingons. It gives the appearance of allowing either two or four players – the map has a line down the middle which would split it reasonably enough for this purpose. Presumably two players split the Federation and the other side has a Klingon and a Romulan player.
The missions of the are clearly of some importance to the game. The green lines on the map appear to chart these (many of the systems have names familiar from the original TV series), there is a rules section labeled "ST Game Enterprise Mission Chart," and one of the scenarios is called "Missions of Enterplize" (a bit of a typo from the base Japanese language used in the game). Other missions include "la Brandy de Camus" and a campaign game.
Like FASA successfully did for its tabletop games, Tsukuda two years later released two boxed sets containing 1:3788-scale Joseph-designed Federation starship gaming miniatures, as game enhancements/expansions to its Invasion of Klingon Empire game, five in total. These plastic miniatures were derived from the Star Trek miniatures GameScience had produced for Task Force Games.
The game was fully licensed by the Paramount Marketing and Licensing Department, and was an indication that the franchise apparently had no qualms about the aggressive, militaristic nature of the game at that point in time. Seven years later though, the franchise was of a decidedly different mind when it reportedly became one of the two reasons for them to retract FASA's Star Trek license, which was a similar warlike product under development at that time as a game supplement for their popular . Most ironically though, FASA's license to produce what eventually became The Role Playing Game, was actually extended in the same year the Japanese game was released, but its conception was a difficult one as no less than four initial attempts were rejected by the franchise for being "too warlike".
