On July 9th, 2025, at a press conference commemorating the 10th anniversary of LINE WORKS—a collaboration tool being serviced in Japan—NAVER Cloud CEO Kim Yu-won shared the achievements over the past decade along with the company’s future vision for the B2B business in Japan. The following is the summary of key highlights.

LINE WORKS’ AI technology transforming the work culture in Japan

Launched in January 2016, LINE WORKS has held the No. 1 share in Japan’s paid workplace messenger market for seven consecutive years since 2017. A deep understanding of Japanese work culture and thorough localization strategy are what led to its success. In Japan, where privacy is highly valued, a personal messenger is rarely used for work. Also, frontline employees who do not have corporate emails—such as shop workers and salesperson—account for higher proportion than office workers. LINE WORKS capitalized on this and developed an all-in-one application where work messenger, calendar, and emails can be managed at once without separate training, captivating the heart of Japanese users.

LINE WORKS is now evolving into an AI-powered workplace platform, going beyond a simple collaboration tool. Already, the voice recording service AiNote, the voice-to-text converter Roger, the AI call response service AiCall, the AI-analysis cloud camera Vision, and the image-recognition document processor OCR are applied to LINE WORKS, receiving strong user feedback. LINE WORKS aims to position itself as an AI tool for workers by enhancing various AI features, including an AI agent that automatically analyzes and processes repetitive and pattern-based tasks.

CLOVA CareCall, AI addressing the welfare challenges of Japan’s aging cities

Another AI-driven service from NAVER Cloud that is gaining significant attention in Japan is CLOVA CareCall (service name in Japan is NAVER CareCall). The service uses AI to call elderly individuals to provide emotional support and monitor health conditions, such as eating and sleeping patterns. If any abnormalities are detected, the system immediately notifies hospitals and local organizations for swift respond. In March, the usability and excellence CareCall were recognized at the Digi-Den Koshien—hosted by Japan’s Cabinet Secretariat, the equivalent of Korea’s Presidential Office— as it became the first service from an international company to reach the finals and placed 5th overall.

Japan has higher elderly population among developed countries, as people who are 65 years old or higher account for 30% of the entire population, which has led to lack of on-site welfare workers. As a result, CLOVA CareCall has gained significant attention as a new welfare infrastructure to address workforce shortages and reduce the gap in caring the elderly. Recently, the city of Izumo in Shimane Prefecture—one of the super-aged cities in Japan—adopted CLOVA CareCall to give check-in calls instead of a social worker. Starting with this, NAVER Cloud aims to seek ways for the company’s AI technologies to become everyday safety net of the country to deliver practical tangible benefits to local communities.
