The "AmazonFBA料金シミュレーター ASIN横断検索" is a browser add-on available on Chrome. Developed by yama0226, this free tool is designed to assist sellers on Amazon Japan, Amazon USA, and Amazon UK.

With this add-on, users can easily search for ASIN codes by simply selecting the code and right-clicking. The add-on then opens the corresponding page on the Amazon FBA fee calculator for the selected country. Additionally, users can perform a bulk search by selecting the "一括検索" option, which allows them to search for ASIN codes across all three Amazon FBA fee calculators simultaneously.

This tool is particularly useful for those involved in domestic reselling, Amazon arbitrage, as well as importing and exporting on Amazon. It helps streamline the process of calculating FBA fees and reduces manual work. If the cross-search feature is not functioning properly, users can adjust the "待機ミリ秒数" (waiting milliseconds) setting by clicking on the icon.
