The Tokyo High Court upheld prison sentences for two bus company executives following a 2016 ski-bus crash that killed 15 university students [1].

The ruling reinforces the legal standard for professional negligence in Japan, holding corporate leadership accountable for preventable disasters that result in mass casualties.

On May 22, the court confirmed the first-instance sentences for bus company president Takahashi Misaku, 64, and operations manager Arai Tsuyoshi, 57 [2]. Takahashi received three years of imprisonment [1], while Arai was sentenced to four years [1].

The accident occurred in January 2016 on a national highway near a ski resort area in Karuizawa-cho, Nagano Prefecture [2]. The court determined that the crash could have been foreseen, which constituted professional negligence [2].

Family members of the victims expressed profound grief and frustration during the proceedings. One bereaved family member said that the phrase "could not have foreseen" is a word used to escape responsibility [2]. Another family member said they had been caused suffering twice [3].

Despite the pain of the legal process, the families emphasized the importance of memory and prevention. A representative for the bereaved families said they want to continue conveying the lessons of the accident in the future [1].

The case centered on whether the company's management had failed to implement necessary safety measures or oversight that could have prevented the vehicle from veering off course [2]. By upholding the original sentences, the High Court rejected the defendants' appeals for leniency.

“The court found the crash could have been foreseen and thus constituted professional negligence.”

This judgment underscores a judicial trend in Japan to penalize corporate executives for systemic safety failures. By upholding the prison terms for professional negligence, the court signals that administrative oversight is a critical component of public safety and that 'unforeseeability' is not a valid legal defense when safety protocols are inadequate.
