The theme is Takeda Shingen, a representative legendary Sengoku warlord, and inspiration was taken from his nickname, ``Tiger of Kai.''
Paired with Echigo's dragon, Uesugi Kenshin, this work features a blue and white gradation inspired by Mt. Fuji.

One of Koga's most popular works is Hooyoroi Hai.
It uses the unusual helmets of Sengoku warlords as a motif to express people's way of life and spirit.

Tea ceremony is a Japanese comprehensive art that developed as a form of education for the samurai class. Sake vessels developed as kaiseki vessels based on this lineage.
Koga describes this work as ``a porcelain cup in the form of a cheek armor, which was naturally derived from the close connection between tea ceremony, Sengoku period military commanders, and crafts, especially pottery.''
