This study investigates the impact of brand awareness on consumers' willingness to use internet-only banking, using Rakuten Bank as an example. It analyzes the effects of brand awareness, brand trust, and brand image on usage intention through multiple regression analysis of 468 valid survey responses. The results indicate that all three factors significantly and positively influence usage intention. Despite Rakuten Bank's branding advantages, it still trails behind the other two internet-only banks in terms of market share. Possible reasons include intense competition among internet-only banks, a lack of widespread awareness of internet-only banking, and insufficient differentiation in services . Recommendations for Rakuten Bank include enhancing brand exposure, strengthening user trust, and cultivating a positive brand image. Additionally, adopting differentiation strategies, improving user experience, and conducting market research are suggested to increase market share and solidify its position in the market.
