Incest has been a taboo topic in Japan for centuries, with historical records indicating that it was often viewed as a shameful and reprehensible practice. The country's cultural narrative emphasizes the importance of maintaining family honor and avoiding social dishonor.
The modern Japanese Penal Code was largely crafted by French legal scholar Gustave Émile Boissonade in the Meiji period (1868-1912) . Boissonade argued that "authority's intervention in private affairs at home is not appropriate and should be disciplined by morals and religion instead" . Japanese officials agreed, feeling it was improper to include such a "disgraceful" crime in the penal code, preferring to rely on social and ethical norms to regulate behavior. japon ensest seks
