from the preamble:
Lady Mijiko's Holiday is designed for GURPS Japan, Advanced Dungeons & Dragons® Oriental Adventures, RuneQuest Land of Ninja, and Bushido. Game stats and notes for each system are given at the end of the adventure. Game-specific information elsewhere is prefaced GURPS, AD&D, RQ and Bushido as appropriate.

The PCs are in service with a daimyo at the start of the adventure. Two factions are vying for the favor of a strategic neutral province, and the leading daimyo of that province is using the birth of his first grandchild as an excuse to hold a tournament. Under cover of the various martial and sporting contests, the opposing factions will be doing some serious politicking, trying to sway him one way or the other.

The PCs are detailed to accompany their lord's younger sister on a visit to her cousin at the castle of an allied clan. They will no doubt be disappointed at the prospect of missing the tournament, but discover that they are part of a subterfuge. For on the return journey they will not be escorting a teenage noblewoman, but a Sumo Grand Champion, on loan for the tournament from a powerful secret ally. Treachery and enemy action are the least of their worries as they try to get the yokozuna safely to the contest.
