The Japanese-style annex Yushintei was designed by Yoshiro Taniguchi, the architect of Togu Palace, and built in 1974. While the functions and modes of hospitality found in the main wing are entirely Western, the annex is a facility where foreign guests are welcomed according to Japanese framework and in purely Japanese style of hospitality. Along with an aesthetic experience characteristic of Japanese dwellings and gardens, Yushintei provides Japanese hospitality through tea, flowers, and foods.
