Although it has been said that modern Japanese santoria for Hansen's disease quarantined patients for their entire lives, there were a small number of cases of "arrested discharges" (a "provisional discharge" when progress of the disease was halted) in the 1920s. To examine the reasons why this practice did not spread in Japan, this paper considers the background that led to the admission of patients who were later discharged from the Kyushu Sanatorium (九州療養所) to analyze two types of discharges: "Arrested discharges" and "discharge by relatives." To do so, this paper draws on the "Patient Identification Records"(身分帳) created by the Fifth Ward United Kyushu Sanatorium (now National Sanatorium Kikuchi Keifuen) to manage patients' admission and discharge from the sanatorium. This analysis clarified specific procedures of "arrested discharges" from the facility, which had previously been completely unknown, and it further revealed that regardless if the patients were discharged as an arrested case or by relatives, emphasis was placed upon their prospects for life after discharge, such as the availability of people to support their care and a minimum standard of living
