A personal testimony details the strict conditions and legal complexities of police custody in Japan.

A recent first-hand account published by Sundacity details a 35-day experience within a Japanese police detention facility, known as a kōchi-sho. The author, who maintains their innocence, describes the environment as a high-pressure system designed to induce confession through isolation, rigid schedules, and limited communication. The narrative highlights the severe psychological impact of the process, including sleep deprivation and the inability to communicate in English, while noting the financial and emotional damage sustained during the ordeal.

The facility is described as a secure, windowless space where suspects are held temporarily while investigations are conducted. According to the account, the author was initially detained for 23 days under standard legal limits before formal charges were filed. However, the total duration extended to 35 days after authorities issued a second arrest on separate allegations, effectively resetting the detention clock. Both cases were ultimately dropped, yet the individual remained confined for the additional period while the matter was reviewed.

Conditions inside the kōchi-sho are characterised by extreme control and discomfort. The author reports residing in a small, all-white cell with harsh fluorescent lighting and no natural light, which obscures the passage of time. There is no furniture other than a hard floor covered in thin carpet, and personal items such as bedding or clothing are strictly prohibited. Meals are delivered through a slot in the door and consist of plain, unpalatable food served cold, with no options for choice or nutrition.

Daily life is governed by an extensive and inflexible routine that dictates every movement and interaction. The schedule includes early wake-up times, fixed meal periods, and limited opportunities for fresh air or hygiene, with showers permitted only once every five days. Communication is restricted to Japanese, and speaking is allowed only when explicitly permitted by officers. The author notes that even basic actions, such as sleeping position or using a washcloth, are subject to strict inspection and regulation.

The text contrasts this approach with the United States legal system, where suspects typically appear before a judge within days and may be released on bail while awaiting trial. In Japan, the focus remains on investigation before charging, a process the author argues can trap innocent people for weeks or months. This delay allows personal lives to collapse, with jobs and family connections severed, while the individual remains powerless inside the facility.

The author emphasises the critical role of embassies in navigating these challenges, noting that diplomatic support helped secure a transfer to a solitary cell due to health conditions. The account provides a list of Japanese phrases used during intake and interrogation, underscoring the linguistic barriers faced by non-native speakers. It concludes with a warning to others about the dangers of the system and the irreversible trauma it can inflict on those caught within it.
