The State Guest Houses (SGH) are national facilities to receive foreign dignitaries, such as monarchs,
presidents and prime ministers, from countries all over the world.
The SGH plays one of the key roles of diplomacy through performing a wide variety of functions,
including accommodating foreign dignitaries and holding summit meetings, signing ceremonies or banquets.
In addition, it is open to the general public as long as its primary activities are not interrupted, thereby contributing to making Japan a tourism-oriented country.
