I'm Swedish, and in Sweden we have rather healthy breakfast habits. Usually fibre rich or whole grain bread. Yoghurt with healthy cereal or granola, and something to drink like tea or coffee.
Such breakfasts are impossible to find at cafes here in Japan. Often we walk around for 30 minutes, and then we settle with a breakfast that is somewhat healthy.
Looks like Japanese people either eat Japanese style breakfast which looks like a whole meal consisting of rice, beans etc, or something sweet, like croissant.
The western style breakfast below cost 430 JPY, 35 SEK.
