Friedman performed the Japanese national anthem at Tokyo Dome on March 27 as part of Japan's Nippon Professional Baseball (NPB) season opening game.

He also played a medley of classic songs by METALLICA, GUNS N' ROSES, Ozzy Osbourne, LED ZEPPELIN, RED HOT CHILI PEPPERS, LENNY KRAVITZ, THE WHITE STRIPES and AEROSMITH during the teams' introduction.

The event was captured on fan-filmed video.

During his February 2025 appearance on The Mistress Carrie Podcast, Friedman discussed his experiences living in Japan since 2003.

When asked what he would say about Japan to people from America and other parts of the world who have never been there, he responded: "It's the closest you can get to being on another planet...

It's an absolute must just to see something that you haven't seen before." He also highlighted Japan's unique cultural aspects, such as domestic music dominating the airwaves.

Friedman emphasized the importance of language skills in navigating different cultures.

In January 2025, he spoke with Canada's The Metal Voice about his experiences as a foreigner in Japan.

When asked if he ever feels isolated or like he doesn't belong, he responded: "I think belonging is extremely overrated...

Why does race even matter? I want the best person for the job." Friedman reflected on his 20-year residency in Japan and how it has influenced him.

Friedman's autobiography, 'Dreaming Japanese', was released on December 3, 2024 via Permuted Press.

His experiences as a gaijin (foreigner) in Japan have given him unique insights into cultural differences.
