I need a bento (lunch box).
I am at an eki (train station).
So this is how Japanese create words! (idea borrowed from PPAP song which was the rage a couple of weeks back).
Ekiben is simply lunch boxes sold at train stations in Japan when you need to fill your stomach on long-distance travel.
There are special ekibens for specific regions too! Prices range from 700Yen to 2000 Yen, depending on what are the contents.
Do not be alarmed if your Ekiben is cold… or only slightly warm. They still tasted yummy! Just don’t listen to PPAP when you’re eating.
