It represents the meeting between Shimazu Nakiakira, the lord of the Satsuma domain (today's Kagoshima) and the influential samurai Saigō Takamori. It was a meeting that took place right in this garden, marking the beginning of a series of events that changed Japan a century and a half ago. The scene is also connected to this year's NHK television taiga drama Segodon, which is about the life of Saigō Takamori.
