Suicide By Train
noun
To fly into something and "commit suicide" (自殺) is suicide by train. Unfortunately, this is a term you should probably be familiar with because it comes up from time to time on the news and around train stations. (Hopefully someday it will no longer be a term you need to know and we can remove it forever.)
とびこみじさつ
The readings come from 飛ぶ, 込, and 自殺. Combine them together to read this entire word.
