Comment by Gilles Beschoor Plug, Ambassador of the Kingdom of the Netherlands to Japan:

The decoration awarded to Dr. Tomonaga is an expression of the deep appreciation and respect of the Government of the Kingdom of the Netherlands for his longstanding efforts to preserve the memories of the war and support the process of reconciliation. Although the decoration is awarded to Dr. Tomonaga as an individual, we would also like to use this occasion to express our heartfelt gratitude to all the members of the committee who have supported this work over many years.
