The question asks how to pay for this and what is the average price in Japanese yen.

However, without more context or information about “this”, it’s difficult to provide a specific answer. Could you please clarify what exactly you are referring to? Is it an event, service, product, or something else?

If you meant to ask about public services or facilities like vending machines, restrooms, etc., the average price in Japan varies widely depending on the location and type of facility. For example:

  • Public toilet: around 100-200 yen
  • Vending machine (drinking water): usually 120-150 yen per bottle

If you meant to ask about a specific product or service, please provide more details so I can help answer your question accurately!
