On 7 November 2025, H.E. Mr. Witchu Vejjajiva, Ambassador of Thailand to Japan, led the officials and staff of the Royal Thai Embassy and Team Thailand together with their spouses to participate in the fifteenth-day Merit-Making Ceremony in dedication to Her Majesty Queen Sirikit The Queen Mother. All participants also took moments of meditation to honor and dedicate merit to Her Majesty The Queen Mother.

The Embassy will continue to hold merit-making on the 50^th, and 100^th day following the passing Her Majesty Queen Sirikit The Queen Mother.
