In Japan, electronic voting was initially implemented by local governments in 2002, and by 2016, it had been used 25 times across 10 cities and towns. However, its use was suspended thereafter. In December 2024, electronic voting was reintroduced in Shijonawate City, Osaka Prefecture, marking its first deployment in eight years and attracting considerable attention. Electronic voting has played a significant role in expediting the vote-counting process and minimizing the occurrence of invalid votes. Nevertheless, it is costly and presents substantial risks, including potential election disruptions due to equipment malfunctions. In response to these concerns, Shijonawate City adopted a standalone electronic voting system, which records data on electromagnetic storage media without connecting the voting machine to a network, thus mitigating the risk of equipment failure. Additionally, while the city endeavored to reduce costs by employing general-purpose machines, the expenses associated with outsourcing to contractors escalated, necessitating financial assistance from the national government. This report, in light of the recent revival of electronic voting, will examine the prospects of implementing electronic voting in national elections and address the technical and legal challenges related to Internet voting, particularly for voters facing difficulties in accessing polling stations.
