Kitakyushu Chamber of Commerce and Industry is the issuer of Paycha, a premium digital voucher program designed to support spending at participating businesses in Kitakyushu. The program brings together the chamber and local shopping districts,商店 associations, and commercial facilities as joint issuing partners, connecting residents with a broad network of local retailers.

The 10th Paycha issue is offered through lottery-based sales, with priority given to Kitakyushu residents. Eligible individuals aged 18 or older can apply for up to ¥50,000 in ¥5,000 increments. The vouchers provide a 20% premium, and the issue has a total value of ¥7.2 billion, including the premium. Selected applicants load their vouchers with cash at Seven Bank ATMs and use them at participating stores during the validity period.

Applications and account setup require the chiica smartphone app, while applications are submitted through an online form. The official Paycha website provides program terms, participating-store information, announcements, app and payment guidance, and customer support details. Support services are also offered at designated venues during the charging period.
