In Japan, you could go to a coffee shop that offers "morning service" or "morning set" (English words written out phonetically in Japanese script) and get toast, a hard-boiled egg, and a tossed salad with coffee or tea.
In Tokyo, you could go to a Pronto or Doutor chain coffee shop and have coffee and a pastry for a reasonable price.
You could even go to McDonald's or Starbucks.
For a more substantial breakfast or other Japanese interpretations of Western food, you could go to one of the local "family restaurant" chains, the best known of which is Jonathan's.
If you have to pay $46 for a meal at any time of the day in Tokyo, you're not really trying.
