Yamaoka

is a vassal of the Land of Fire's daimyō, Ikkyū Madoka.

Personality
From what has been seen, Yamaoka is a dutiful and respectful vassal of the daimyō.

Appearance
Yamaoka is an elderly man with short, light-coloured hair which he wears in a pompadour style while keeping the sides short. He also has dark-coloured eyes framed by half-frame glasses and sports a bushy, well-groomed moustache. He wears a white shirt with an upturned collar and a string being used as a bow-tie, with a dark-coloured tuxedo jacket, a vest, pocket square along with pinstriped pants and simple shoes.

Post-Momoshiki Arc
During their visit to Konoha, Yamaoka was seen speaking with a shopkeeper after the daimyō and his son Tentō left. He was later charged with looking after young Tentō when Ikkyū departed for his meeting with the Seventh Hokage.

After Ikkyū left, Tentō asked Yamaoka how many cases of collectible cards were left in the store. Yamaoka advised the young man that each customer was limited to three packs only. Tentō, however, informs Yamaoka that he will simply buy the entire store.
