Mr. Takagawa is an elderly Japanese male, with gray hair, side burns, and a moustache. He wears spectacles and a maroon bow tie.
He is annoyed easily by his janitor, Kenji. He is stubborn and insistent, and really wants people to visit his museum. But he is protective of the world and would help the gang to stop the Black Samurai.
Scooby-Doo! and the Samurai Sword
When he saw his janitor staring into space he got very annoyed and took him to see the Black Samurai. He told him that the Black Samurai was going to make the museum more popular and told his janitor part of the Black Samurai's history. Then the doors slammed shut and a kind of mist swirled into the room. Suddenly the Black Samurai became 'alive' again and dramatically exited the room with lots of blue lightning and flying.
He went to visit Miss Mirimoto to tell her to guard her scroll 'as the Black Samurai would come to get it'. She appeared skeptical and told Sojo, her loyal guard, to take him to his seat. Sojo grabbed Takagawa and Miss Mirimoto told him that she thought the scroll was perfectly safe behind her walls.
He explained to the gang, the legend of the Black Samurai, and how he intends to find the Sword of Doom and free his spirit. He than accompanies the gang to stop the Black Samurai from finding the sword.
When it was revealed that Ms. Mirimoto plans to free the real Black Samurai and traps the gang in his museum, he vows to protect the world like a modern-day samurai.
After the Black Samurai was defeated, he had a statue of Scooby-Doo made in his honor, for his bravery and courage.
