  **第一項**  保護処分の継続中、拘禁刑又は拘留の刑が確定したときは、先に刑を執行する。拘禁刑又は拘留の刑が確定してその執行前保護処分がなされたときも、同様である。
  <sup>art-57/par-1 · https://japanlaw.org/ja/juvenile-act/art-57/par-1 · https://japanlaw.org/l/323AC0000000168/art-57/par-1</sup>
  If a sentence of imprisonment or penal detention becomes final and binding in the course of the disposition for rehabilitation of an adjudicated delinquent, the sentence is executed first. The same applies if a sentence of imprisonment or penal detention has become final and binding and the disposition for rehabilitation of an adjudicated delinquent is made before the sentence is executed.
