The associated production of a scalar (/ital H/) and pseudoscalar (/ital P/)Higgs boson at the /ital e//sup +/e/sup /minus// collider TRISTAN at KEK isdiscussed within the framework of minimal supersymmetry. We first discussconstraints on the model from the nonobservation of radiative decays of the/Upsilon/. We then show that a substantially larger region of parameter spacecan be probed already at /radical//ital s/ =60 GeV, where a total /ital HP/ crosssection in excess of 1 pb is possible. We discuss the clean/tau//sup +//tau//sup /minus// pair signal in some detail and show how itsopening angle can be used to reconstruct the mass of the parent Higgs boson.Some remarks on purely hadronic decay final states are also presented.
