Golden Week got off to a horrific start Sunday as a bus packed with tourists headed for Tokyo Disneyland ran edgewise into a wall on an expressway in Gunma Prefecture, killing seven people and injuring 39 others.

The bus, which left Kanazawa, Ishikawa Prefecture, at around 10 p.m. Saturday with 45 passengers, plowed into the leading edge of a 3-meter-high guard wall on the Kanetsu Expressway in Fujioka at around 4:40 a.m., police said. The wall sliced through its left side.

According to its final speedometer reading, the bus may have hit the wall at 92 kph.
