Rules for Determining Prices

KOMEHYOオークションは

「競り上がり式」オークションです

In an ascending-bid auction, bidding starts at the "starting bid price".Multiple bidders place bids by offering at least the minimum increment above the current bid. The bidder who places the highest bid wins the auction. Because price changes can be tracked in real time, bidders can monitor the current status and make informed decisions, leading to transactions at satisfactory prices.

What is the minimum add-on amount?

The minimum add-on amount is the smallest amount you must add to the current bid. It ensures that bidding progresses in reasonable price steps and helps maintain fairness and efficiency throughout the auction process.

Current Price	Minimum Add-on Amount
Less than 50,000 yen	1,000 yen
50,000 yen or more but less than 100,000 yen	2,000 yen
100,000 yen or more but less than 300,000 yen	5,000 yen
More than 300,000 yen but less than 500,000 yen	10,000 yen
500,000 yen or more but less than 1,000,000 yen	20,000 yen
More than 1 million yen	30,000 yen
★Watches only, over 300,000 yen	10,000 yen

Basic Rules for Bidding

Bids must be in increments of 1,000 yen.

All bid amounts must be in units of 1,000 yen. Fractional amounts are not accepted.

Bids must be at least the current price + the minimum add-on amount.

To be valid, your bid must be equal to or higher than this total amount.

Bids cannot be canceled once placed

In principle, bids cannot be changed. However, the highest bidder may reduce their bid, but only to the amount displayed on the bidding screen: the 'current price' plus the 'minimum add-on amount'.

Automatic time extension for last-minute bids.

If a bid is placed within the last five minutes of the auction, the closing time will be automatically extended by five minutes. (Up to a maximum of 23:59:00 JST)

Some items can be won at the immediate purchase price.

Certain items should be sold immediately if you bid the 'Instant Buyout' price.

If the reserve price is not met, the item enters negotiation.

If the highest bid does not meet the minimum bid price, the seller will decide whether the sale is 'successful' or 'unsuccessful' on the pending negotiation day.

What is the minimum bid price?

最低落札価格とは、商品が落札されるためにあらかじめ出品者が設定する最低金額のことです。
この価格に達せず入札終了となった場合、保留交渉日に出品者が最終金額で「成立」「不成立」の判断をします。

What is the starting bid price?

検品をもとに当社が設定します。入札開始時のスタート金額です。この金額から入札が始まり、以降は最低上乗せ額以上の金額で入札されていきます。

How Prices Are Determined

The final result will vary depending on whether "minimum bid price" is set or not and whether there are multiple bids. Please refer to the flowchart below for details.

Why isn’t the highest bid price always the winning price?

At KOMEHYO auctions, the highest bidder is the winner, but the actual winning bid price is determined by how much the next highest bidder offered. This means the price reflects genuine demand—not an attempt to artificially raise the price—but results from fair competition among buyers. This is the fundamental mechanism of auctions.
