Electrical energy consumption through electronic devices has been rapidly increasing in Japan as technology becomes more accessible and cheaper. There are an estimated 95 million people in the nation, consuming approximately 3 to 4 watts of energy each day for the purpose of recharging their gadgets and electronics. This poses an imminent challenge for the future of Japan’s energy security and sustainability. This study was conducted to determine if the implementation of solar charging alternatives in public are feasible in Japan, which may help reduce the depletion of electrical energy in the country. The research was collected and conducted through descriptive research design which included 45 participants, both Japanese and Foreign residents in Japan. A Google Forms questionnaire was used, and the data gathered consisted of 5 sections, designed to collect the opinions of our audience in regard to solar energy. Based on the results, it was concluded that individuals in Japan are aware of the increasing energy consumption in the country and are willing to utilize free solar energy alternatives/outlets in public as a way of charging their electronic devices should it be made available. Thus, it presents a market for opportunities to reduce energy consumption within the nation. Furthermore, the researchers recommend that to increase the accessibility of this project, collaboration with private companies and government subsidies through funding and public support is advised. Moreover, designing these solar charging alternatives in the form of cost-efficient kiosks or stations may aid in making the project's expansion more effective.
