Tsushima is a board wargame published by Game Designers' Workshop (GDW) in 1975 that simulates naval battles during the Russo-Japanese War of 1904-1905.
The expanding geographical interests of Russia and Japan collided in the late 19th century, and resulted in a formal declaration of war in 1904.
[3] Following the demise of SPI, Hobby Japan acquired the rights to The Russo-Japanese War and printed a Japanese-language version in Command #55 (March–April 2004).
"[6] In the 1977 book The Comprehensive Guide to Board Wargaming, Nicholas Palmer commented "Tsushima can be played with Port Arthur, or with abstract rules reflecting the course of the land action; the former seems to be the most interesting version, with the latter rather simple.
"[2] In Issue 6 of the UK wargaming magazine Phoenix, Rob Gibson called Tsushima "an excellent game, recreating the feel of the period with its formalised lines of battle and the uncertainties of operating the modern steam-driven warships."
[...] The strategic movement phases are fun, there are interesting rules about morale, repairing damaged ships, secondary weapons, spotting, town raids, mines."
