The name for these boxed lunches used in Taiwan is biandang, a Chinese adaptation of the original Japanese name for them, bento. The first thing anyone in Taiwan thinks of whenever someone mentions the beginnings of these lunches is those sold by the TRA years and years ago.
台灣的「便當」一詞是從日語「弁當」演變過來的。一般人提到便當的起源，第一個想到的可能就是鐵路局供應的便當。
