Today the relationship between Japan and Thailand is excellent. Starting with the frequent visits between the Royal Family of Thailand and Imperial Family of Japan, we can witness active exchanges and close cooperation in various areas which encompass not only trade, investment and cultural exchange but also political and security interaction in the international arena. However if we look back on our history, we will find that this wonderful relationship did not develop naturally but evolved out of continuous efforts of our ancestors who were involved in various exchanges and cooperation over the past 600 years, the accumulation of which has resulted in today’s rich and multi-layered cooperative relationship.
