Blockchain-Based Digital Vouchers as a Key Driver for Japanese Regional Tourism

The tourism sector in Japan has been one of the key sectors put forward by the Japanese government to rejuvenate its economy. In recent years, significant efforts have been made to attract tourists and enrich their overall experience. However, a significant challenge remains: the lack of convenient payment methods beyond cash in rural areas. In this study, we propose a blockchain-based digital voucher system to facilitate digital payments for international tourists visiting Japan. Our research is two-fold. First, we design a token system that seamlessly integrates with existing voucher solutions commonly issued by local governments in Japan, streamlining the processes of issuance and management. Second, we explore the potential of digital vouchers to enhance the development of the tourism industry in rural areas, thereby promoting a more inclusive and sustainable tourism ecosystem across Japan.
