In Japan there are plenty of snacks like potato chips, cream puffs etc. The chips come in many varieties and cheap too. Take for example the spicy chips (126 gm) is less than S$2. The cream puffs are sweet and soft and cost 50 cents each. I love the egg and chicken sandwiches ($3). The bread for the sandwiches are tender and soft.
If you love eating, Japan is a good place to be in. I've since gained 3 kilos since living in Japan.
