Or Yohai-sho, yohaiden. 'Place (or hall) for worship from afar (yohai)'. A location, often a small building, used for worship of another holy site from a distance, or for worship of an inaccessible 'inner' shrine (okumiya) from a more convenient spot. From the 1870's yohai-sho of the Ise jingu were established throughout Japan (some became provincial kotai jingu) as part of the effort by Ise priests to focus the worship of the population on the Ise shrines. In prewar Japan (and until 1947) the term yohai was used for the ceremony of bowing to the imperial palace from schools.
