On paying the listed price

For everything that I've purchased in Japan, I have paid the marked price. Taxes were included in this price, so mental math to figure out what the final bill was going to be was not necessary. Also, tipping is not required, as this has also been calculated into the final bill.

So, when I purchased a sweet bean filled pancake sandwich that had its price marked as 136 yen, I paid 136 yen for this mid-afternoon snack.
