Akira Kobayashi
The studio Nikkatsu made modern yakuza films under the or "Borderless Action" moniker, which, unlike other studios in the genre, borrowed heavily from Hollywood gangster films. These are typified by the "Wataridori" series that started in 1959 and star Akira Kobayashi and, in most installments, Joe Shishido. Another popular series in the style was the "Kenjū Buraichō" series starring Keiichirō Akagi and, again, Joe Shishido. However, this series ended abruptly in 1961 due to Akagi's death.
