Hello, having an APEC visa on your old passport usually means that the visa is for an APEC economic member country. If you hold a valid APEC business travel card, after a new passport is issued, you can theoretically leave Japan with the APEC visa and travel card in your old passport. However, whether you can leave the country depends on Japan’s current entry policy and your personal circumstances. It is recommended to consult the Japanese embassy or consulate before traveling to obtain the most accurate entry information.
