Naturally, when contemplating arbitration, each party will want to nominate as many arbitrators to the panel as possible to increase their chances of obtaining a favorable outcome. If one side gets to pick all of the arbitrators to a dispute, it is more likely that the dispute will be resolved in their favor. However, arbitration agreements that grant too much power to only one party are invalid and therefore, clauses granting one party unilateral power to appoint arbitrators is invalid under Japanese law.
