The three Ōtani Expeditions (1902–1914) constitute the first non-Western attempt to carry out systematic research in Central Asia. The mastermind behind these Japanese enterprises was Ōtani Kōzui, the 22nd lord-abbot of the Western Honganji temple in Kyoto and the patriarch of the Honpa Honganji denomination of the Jōdo Shinshū sect, which was and remains the largest Buddhist community in Japan. Kōzui's position as a monk during the period the expeditions were carried out reveals his religious motivation as the planner and sponsor of these research trips. Inspired by the 7th century traveler-monk Xuanzang, the main purpose of the Ōtani Expeditions was therefore to find the routes through which Buddhism had passed before reaching Japan. This is what makes them unique when compared with other exploration missions.
