Let's take a closer look at the man now poised to lead Japan.
Kishida was born into politics -- seemingly destined to follow in the footsteps of his lawmaker father and grandfather. After just five years as a banker Kishida first dipped his toes into public service. He became his father's secretary. In 1993, he took over that Hiroshima seat and has been re-elected eight times.
Eventually, he was tapped to become Japan's top diplomat. Kishida held that role for over 4 straight years, a record in post-war Japan. As foreign minister he was instrumental in bringing Barack Obama to his home city.
It marked the first time a sitting US president saw the destructive legacy of America's atomic bombing up close.
Kishida also worked to ease long-standing tensions with Seoul. In 2015, he struck a deal with his South Korean counterpart on the politically sensitive issue surrounding people referred to as wartime comfort women.
The 64-year-old is known as a soft-spoken, honest politician. Now, a man called too serious -- or even boring -- has reached a pinnacle of political achievement.
