Ogasawara was initially interested in baseball when he was younger, but he had a passing interest in video games while visiting his friends' homes during middle school. He did not become invested in video games until he was living by himself during his college years. Ogasawara was introduced to Nobunaga no Yabou Sengoku Gunyuuden (the third Nobunaga's Ambition title) and played it rigorously during his free time.
