Tokyo: Relations between Japan and Southeast Asia are growing closer, marked by increasing people-to-people exchanges and a deepening interest in each other's cultures. Through post-World War II reconciliation and decades of cooperation, the mutual trust between Japan and Southeast Asia has strengthened, ushering in a new phase of their relationship.
According to Thai News Agency, the 2026 Thai Festival Tokyo, held in May at Yoyogi Park, attracted over 280,000 visitors, showcasing authentic Thai cuisine and cultural performances. The festival, which first started in 2000, featured T-pop artists and actors, drawing large crowds and even necessitating entry restrictions at times. The popularity of such events reflects a growing interest in Thai entertainment among Japanese audiences.
Similarly, the Laos Festival 2026, also hosted at Yoyogi Park, saw the attendance of Japan's Princess Aiko, who participated in the opening ceremony with Lao dignitaries. Such festivals, celebrating various Southeast Asian countries, draw significant crowds annually, illustrating the vibrant cultural exchange between Japan and Southeast Asia.
Tourism between the regions has also seen substantial growth. The Japan National Tourism Organization reported that in 2025, over 42 million foreign visitors traveled to Japan, with 4.8 million from six major ASEAN member states. This figure represents a tenfold increase since the launch of the Visit Japan campaign in 2003, highlighting Japan's appeal as a travel destination.
The Singapore-based ISEAS - Yusof Ishak Institute conducted a survey in 2026, revealing Japan as the top holiday destination for ASEAN respondents, with 32.5% indicating a preference for Japan. This popularity underscores the strong cultural and tourist ties between Japan and Southeast Asia.
Trust in Japan remains high among Southeast Asian countries. The aforementioned survey found that 65.6% of respondents trusted Japan, the highest among surveyed countries and regions, including the United States and China. Respondents cited Japan's respect for international law and economic resources as reasons for their trust.
While Japan's historical ties with Southeast Asia have been complex, post-war efforts have fostered strong relationships. Emperor Naruhito and Philippine President Ferdinand Marcos Jr. highlighted this progress during a state banquet in May, celebrating the 70th anniversary of diplomatic relations between Japan and the Philippines. President Marcos described the current bilateral ties as a 'platinum age,' reflecting the growth of their Comprehensive Strategic Partnership.
The principles set forth by the Fukuda Doctrine in 1977 continue to guide Japan's relations with Southeast Asia. As the doctrine approaches its 50th anniversary in 2027, there is optimism that Japan and Southeast Asia will continue to deepen their exchanges and uphold the doctrine's principles in the years to come.
