Correspondence

Official letters that His Majesty the Emperor sends to foreign Heads of State, or those He writes in reply to the letters from foreign Heads of State, are referred to as Imperial Letters. Letters or replies to letters written by Their Majesties the Emperor and Empress or either of Their Majesties to persons other than foreign Heads of State may also be referred to as Imperial Letters.

Imperial Telegrams are those sent by His Majesty the Emperor or Their Majesties on such important occasions as a foreign State's National Day or Independence Day, the birthday of a King or Queen, on the occasion of the demise of a Head of State, or a major disaster. Replies to telegrams received on the occasion of either of Their Majesties' birthdays are also referred to as Imperial Telegrams.

By corresponding through these letters and telegrams, Their Majesties the Emperor and Empress contribute to the fostering friendly relations with foreign countries.
