Masahito Moriyama

is a Japanese politician. He is a member of the ruling Liberal Democratic Party and a former member of the House of Representatives in the National Diet (national legislature). A native of Nishinomiya, Hyogo, and an alumnus of the University of Tokyo, he joined the Ministry of Transport in 1977. He was first elected to the House of Representatives in 2005 but lost his seat in the 2009 General Election, regaining it in 2012. During his time out of office, he matriculated as a postgraduate student and studied international law and business at Kobe University, which is located in his constituency. He earned a Master’s degree in Law in 2011, a PhD in International Law in 2013, and an additional PhD in Business Studies in 2014.

In 2024, Moriyama won a no-confidence motion issued by the Constitutional Democratic Party after reports emerged that he received a letter of recommendation and campaign support from an organization linked to the Unification Church during the 2021 Japanese general election.

On 10 April 2024, Moriyama was among the guests invited to the state dinner hosted by U.S. President Joe Biden in honor of Prime Minister Fumio Kishida at the White House.
