Kirk here with an inquiry that the page received: “Hello! I called the waste management office of Kumamoto to register my mattress for disposal and they told me I will be paying 10,900. I went to the konbini to get stickers as instructed from the call but they showed me a 500-yen and 900-yen sticker. I am a little confused about the ¥10,900. Should I buy stickers that would total to ¥10,900?” Does anyone have any insight? Does the fee sound about right?
