A Japanese auction in procurement is a type of auction where suppliers or bidders compete to offer the lowest price for goods or services, but with a unique twist: as the auction progresses, the price decreases in steps rather than being bid down by competitors. In a Japanese auction, the price starts at a high point and decreases over time, but the key difference from a Dutch auction is that suppliers can submit bids at any point while the price is dropping.
However, the first supplier to place a bid accepts the price at that moment, which ends the auction. The auction continues until one supplier accepts the price.
Japanese auctions are not as common in procurement as other types (like reverse or Dutch auctions), but they can be used in specific circumstances where time is of the essence, and the goal is to secure an agreement quickly.
