Social issues I have worked on

- Removing the barriers to consumer-generated communication, and democratizing it
- Digitalization of marketing in the Chinese market
- Barriers to opening a store in Japanese e-commerce
- The spread of smartphones in Japan and everyday use of the internet on them
- Creating opportunities for Japanese companies to grow sales in overseas (Chinese) markets as Japan's population declines
- Strengthening outbound communication and visitor acquisition to capture growth in inbound tourism — especially visitors from China — as Japan's population declines
What I have done

- Eliminated marketplace listing fees for Yahoo! Shopping (the "e-commerce revolution") and expanded usage by strengthening e-commerce benefits for Yahoo! Premium members
- Launched Y!mobile and led the shift of telecom line sales online. Strengthened bundling of the Yahoo! Premium membership program and preferential promotions for SoftBank smartphone users in e-commerce
- Built a network of Chinese influencers living in Japan and supported marketing for major Japanese department stores, other retailers, and local governments
- Established new entertainment content formats combining the reach of broadcasting with the interactivity of the internet (e.g., helping bring vote-based audition programs to the Japanese market)
