Product size is often one of the first things international food brands have to adjust when entering the Japanese market. Not only is the average Japanese home too small to store western-sized jumbo packages, Japanese eating habits are typically different from their overseas counterparts.
But it's not just foreign firms that learn optimizing package size can lead to more sales.

Kewpie reduced the volume of its salad dressings from 200 to 170 milliliters--and was surprised to see a 5% increase in order volume versus the same period last year.
According to a Nikkei article, the company attributes the bounce to the fact that the package better suits current Japanese demographics. With household sizes shrinking, too many people were consistently throwing out bottles whose "best by" date arrived before the product could be entirely consumed. Plus, many more kinds dressings are available at supermarkets these days so consumers have a larger variety at home, resulting in extended usage cycles for each bottle.
However, Kewpie cut the price to reflect the 15% reduction in size, so it could be that stores are ordering more to satisfy consumer demand for cheaper products of all types--something Kewpie apparently adamantly denies.
