Quick Answer
ゆうパック (Yu-Pack) is Japan Post's standard parcel service. Pricing is based on both size and distance (unlike flat-rate Mercari-bin). It includes tracking and up to ¥300,000 insurance, and works for all selling platforms — not just Mercari.

FAQ
Q: Is Yu-Pack cheaper than Rakuraku Mercari-bin?
For nearby prefectures, Yu-Pack can be cheaper. For long distances (e.g., Hokkaido to Okinawa), Rakuraku Mercari-bin's flat rate is usually better. Always compare both.
Q: Can I use Yu-Pack on Mercari?
Yes, but it will not be anonymous — your real address appears on the label. Use ゆうゆうメルカリ便 for anonymous Japan Post shipping on Mercari.
Q: What is the 持込割引 (bring-in discount)?
If you bring the package to the post office counter yourself (rather than requesting home pickup), you get ¥120 off the total price.
