Swords of the Daimyo (OA1), Oriental Adventures adventure for AD&D 1st ed, by David ‘Zeb’ Cook.
“From the log of the Leaping Dolphin:
‘110th Day: The gale nae stops for twa days. My ship is driven before it and the magus is as helpless as a wee babe. Akito names the winds tai-fun in his heathen tongue…’
Drawn by the lure of adventure and riches, a crew of seamen sails valiantly into uncharted seas. In the squalid dens of the port districts, tales hint at a land of untold riches across the waves. But getting there is only the beginning.
Across the waters lies Kozakura, a land of mystery and danger. There you will discover new cultures, strange values, secret powers, and fabulous terrors. For Kozakura is a land of Oriental Adventures.
Swords of the Daimyo is the first module designed for use with the AD&D Oriental Adventures rule book. Swords of the Daimyo includes descriptions and maps of the island of Kozakura, detailed information and maps of Miyami Province of Kozakura, and a series of adventures to introduce old and new player characters to the intrigue of the Orient.”
