Showing a keen eye for an opportunity, one of the drink manufacturers released the "Railway Bento Boxes" series, containing snack toys of bento--lunch boxes--from 24 locations around Japan. Each of the toys had an image of the distinctive scenery of its locale sitting above a replica of the local specialty bento, with a cup of tea beside it, creating an unchanging train-window scene.
飲料商看準這個現象，推出隨茶附贈的「火車便當食玩系列」，總共有日本 24 個地區的鐵路風情，食玩上方是該地區的地方風景，下方則是在地特殊的火車便當，只有便當旁的茶飲料，是每個車窗旁唯一不變的物品。
