Sweets are a good gauge of any country's soul. They tell you a lot about the people and their tastes.
When my son was working in Singapore recently, he wisely returned with a selection of Japanese sweets and snacks that were 'very interesting'. The three large packs are Strawberry, Melon, and Mixed 'fruit gums'. Very nice (even though I don't really eat sweets).
But the most interesting however were the two small packs at the bottom of the picture. One was a strange Peach-flavoured jelly that one squeezes out into your mouth like clear pale-pink Silicone from a tube. The other was a tiny pack of rather sweet preserved Pork (below). Both were quite a revelation. Wonderful things to have in your pocket at all times.
Knowing the Japanese penchant for hard work, I quite expect they were designed to keep Japanese office workers happily at their desks well into the night.
