Tier IV Inc. (Umi no Mori Park shuttle bus, Koto City government demonstration)

Analyst brief

The record holds one malfunction entry: a February 2026 accident in a Koto Ward government shuttle demonstration, attributed to a route-deviation detection failure, severity 1. The index of 6.4 and 16.1 percentile place this entity near the bottom of the 'other' category, reflecting minimal recorded history. The finding derives from a government-run pilot program rather than press investigation, and the causal attribution to a specific detection failure comes from that official account. The record is a single low-severity event with no pattern of recurrence on file.
