Hiroshi Yamamoto
The Yama-Ichi War ended with the retirement of Hiroshi Yamamoto, which was arbitrated by one of the most respected bosses, Seijo Inagawa. After that, the clan elected "wakagashira" Yoshinori Watanabe as 5th "kumichō" of the organization. Masaru Takumi ("kumichō" of Takumi-gumi) was elected as "wakagashira". He was so powerful and respected within the organization that his influence overshadowed that of "kumichō" to some extent.
