During Emperor Shirakawa's reign, there was an upper and lower hokumen inside the imperial palace. The upper hokumen housed some shodaibu (public servants of the fourth and fifth rank) while the lower hokumen housed many efushoshijo (guardian servant, inspectors). Members of the lower hokumen would, followed by other servants, accompany the emperor on imperial outings armed with arrows.'
