The countries will next year commemorate 120 years since the establishment of diplomatic ties between them, one of the oldest such relationships in the region. It will be an auspicious occasion to further strengthen their friendship and cooperation. Ties between the two countries go back several centuries to the Ayutthaya period, when Japanese traders settled in the old capital to do business alongside traders from Portugal and Holland, among others. Some of outstanding members of the Japanese expatriate community back then also served the Thai court in various capacities.

The earliest known records of relations between Ryukyu (Okinawa) and Ayutthaya probably date as far back as the 15th century. By the 17th century active trade between the two countries had become prominent, as evidenced by the flourishing Japanese community in Ayutthaya at the time.

Their contribution can be seen through mural paintings and archaeological remains, manifestations of a time-tested friendship.

In modern times, Japanese investment and business in Thailand and its artistic and cultural influence are both highly visible. Thailand was fortunate that Japan did not wage war on its territory during World War II. This explains why Thailand does not harbour any kind of animosity towards Japan in the way some countries still do. Both sides have mutual trust and respect, qualities that are sometimes lacking in Thailand's relations with other countries.

The most interesting aspect of this royal visit was that the Japanese emperor and empress made a lasting impression on the hearts and minds of the Thai people.

For Thais, the monarchy has been a stabilising force that holds the country together in times of peace and of national crisis. As the guardian of age-old tradition, the monarchy provides a sense of continuity and reassurance whenever there is doubt and uncertainty. HM the King can speak with candour on the state of the country. After all, he has reigned for 60 years and has seen numerous prime ministers come and go. He knows every nook and cranny of his Kingdom and, most importantly, has exceptional understanding of the Constitution.

The ties between the two royal houses have had a positive influence on the development of Thai-Japanese relations. The countries recently concluded negotiations on a free-trade agreement that is now awaiting final adoption and ratification. Thailand considers Japan a strategic and economic partner, and vice versa. The two democracies' strategic and security cooperation is pivotal to peace and stability in the region. Moreover, both are allies of the US. Their shared security objectives have so far served the region well.

Japan's emperor is no stranger to Thailand: he has been here six times as crown prince and twice since he ascended the throne. The Japanese imperial family has a very close relationship with the Thai monarchy. For instance, Crown Prince Naruhito and Prince Akishino often visit Thailand. Akishino is also well known in Thailand as an expert on Thai catfish and wildfowl. Members of Thai royal family also visit Japan quite regularly.

Last year Japanese tourists ranked second after Malaysians in the number of arrivals, with close to one million visiting. More than 120,00 Thais visited Japan last year, making them the seventh largest group of visitors there. Both sides are confident that the number of tourists will increase both ways in future.

The cordial ties between the two monarchies and the people-to-people exchange ensure that the friendship and cooperation between the two countries rests on solid foundations.
