The auction page

Bidding is automatic
Using the minimum increment for the price range, the system bids the amount most favourable to the bidder.
Price range Minimum increment
< ¥1,000 ¥10
< ¥10,000 ¥100
< ¥30,000 ¥500
< ¥100,000 ¥1,000
< ¥500,000 ¥5,000
< ¥2,000,000 ¥10,000
< ¥5,000,000 ¥50,000
≥ ¥5,000,000 ¥100,000
Automatic extension
If a bid is placed within 5 minutes of the close, the end time is extended by the minutes remaining plus 5 minutes.
Time remaining
The countdown begins once the first bid has been placed, and the auction ends when the set period has elapsed. An auction with no bids never starts.
Item details > Duration
The auction ends when this many days have passed from the day of the first bid.
Pay a deposit (option)
On an auction carrying this option you are asked to pay a deposit before you can bid.
  • If you win: the amount billed = (winning price − the deposit already paid) + shipping.
  • If you do not win: the deposit is refunded. Please request the refund from Contact. (PayPal or cryptocurrency transfer fees are deducted.)

The deposit is forfeited if a participant cancels after winning for reasons of their own, delays payment, obstructs the auction, or does anything the operator judges to be equivalent. That judgement is made by the operator and is not published. Please carry a won transaction through without incident.

Reserve price
An auction carrying this option can only be won at or above the reserve price that has been set.
Buy-It-Now price
An auction carrying this option can be won at the Buy-It-Now price. Whatever the price was until then, the Buy-It-Now price becomes the winning price.
Skip bid confirmation
Skips the confirmation step, so clicking the bid button places the bid immediately.
Apply to bid (option)
On an auction carrying this option you apply to the seller for permission before bidding. Only approved participants can take part.
Open Time
Bidding becomes possible from this date and time. Before it you can view the auction page but cannot bid — a showcase period.
Payment methods
PayPal, cryptocurrency and bank transfer are available. Check in advance which of them a given listing accepts.
  • PayPal — a 4.2% PayPal fee applies, both to the winning payment and to a bid deposit.
  • Cryptocurrency — a 0.5% payment fee applies, both to the winning payment and to a bid deposit.
  • Bank transfer — available within Japan only. Transfer fees are paid by the buyer. Nothing is added to the winning price.

Cryptocurrency accepted as of 2026/09/01: XRP

Operator listings accept PayPal, cryptocurrency and bank transfer. On a Market Seller listing, the seller chooses from those methods.

Shipping
When the seller is in Japan and has chosen prepaid shipping, the cost is calculated automatically from the winner's address, whether that is in Japan or overseas. When the seller has chosen freight collect, no shipping is added to the amount billed. Freight collect is never applied to a winner outside Japan: international shipping is calculated instead.
Questions
You can ask the seller about the item.
When you cannot bid
You cannot bid if the seller has blacklisted you, while your account is suspended, on an auction the administrator has placed on hold, or on your own listings.

Payment

Once you have won, the item appears under My Page > Won Items. Items bought from the same seller are combined into a single payment.

Payment currency
  • PayPal — payment is in Japanese yen. Whatever currency the auction is displayed in, the amount billed is always JPY. A fee of 4.2% is added.
  • Bank transfer — payment is in Japanese yen. Whatever currency the auction is displayed in, the amount billed is always JPY. No fee is charged.
  • Cryptocurrency — the amount is converted from the auction's display currency at that day's cryptocurrency rate, and billed in cryptocurrency. A fee of 0.5% is added.
Paid, Received
For PayPal and cryptocurrency, the bar advances to Paid and Received automatically once the incoming payment is confirmed. For a bank transfer, click the Paid panel yourself; the bar moves on when the seller confirms receipt.

The payment deadline is 3 days, counting the day the auction ends. If payment is not completed by 23:59 Japan time on the third day, the deposit is forfeited on an auction where one was set. Please watch the deadline.

Shipped
When the seller has shipped, they click the Shipped panel to advance the bar.
Arrived
Once you have received the item, click the Arrived panel.
