Dias Police: Police from Another Country(2016)

Dias Police: Police from Another Country is a Japanese drama series centered on Tokyo's underground community of approximately 150,000 undocumented immigrants. Living outside official recognition and in harsh conditions, these migrants have built a shadow society complete with an unlicensed bank, unauthorized hospital, and their own police force—the Dias Police. At the heart of this clandestine world stands Saki Kubozuka, a taciturn officer of mysterious age and nationality. Despite his quiet demeanor, Kubozuka possesses a strong moral compass and genuine compassion for the vulnerable. He navigates the complex duty of maintaining order within the illegal community while protecting those who have nowhere else to turn. The series explores themes of justice, belonging, and humanity in the margins of society.
