Matsuken is a character who appears in front of various “moyamoya” of everyday life, and is a bright and exhilarating character with his buddy pine dog.
By playing a character with the motif of Mr. Matsudaira himself, we will deliver the charm of “Matsuken Anime”.

Comment from Ken Matsudaira

“I was surprised when I heard the story. I never thought that a character with a motif of myself would become an anime. But I thought it was a very interesting project.
It’s the first time I’ve played “Matsuken” with myself as a model, but Matsuken and Matsu dogs will be able to brighten up everyone’s moyamoya and be happy.
I’m glad that I can bring you energy and smiles through this work. Please look forward to the distribution. ”

Sumire Uesaka has decided to play the role of a partner, a pine dog

Sumire Uesaka, who is widely active as a popular voice actor and artist, will be in charge of Matsuken’s partner, Matsu Inu. The pine dog is an important existence that challenges the people with Matsuken to solve the confusion of people. With a sharp sense of smell, he finds out the cause of moyamoya, and sometimes adds a bitter tsukkomi to support Matsuken as a partner to support Matsuken.

Comment from Sumire Uesaka

“I don’t have many opportunities to play a dog character, so I was really looking forward to taking on the unique role of a pine dog.
The pine dog is a very expressive and lively character. I acted with the intention of making the work even more enjoyable.
I am also excited to see the world view of “Matsuken Samba”, which I have been familiar with since I was a child, as an anime. Please look forward to it. ”

Daisuke Namikawa plays a variety of characters

Daisuke Namikawa plays various characters that appear in front of Matsuken and the others in each story.
By playing the unique characters that appear each time, such as office workers, bosses, clerks, friends, etc., you can color the world of “Matsuken Anime”.

Comment from Daisuke Namikawa

“It was a great honor to hear that you could participate in a work starring Ken Matsudaira.
This time, I was in charge of various characters other than Matsuken and Matsu Inu, and I was conscious of being able to express the individuality of each role.
Each of the characters that appear in this work has a “moyamoya”.
I would be happy if you could feel the thoughts and background in the short scene.
It is a work that can be enjoyed casually, depicting events that everyone can relate to. Please take a look. ”
