Japanese heavy metal trio Ningen Isu has announced their "60th Birthday Memorial Tour 'Ryouki Shinsei'" (Strange Rebirth), kicking off May 6th across eight cities nationwide.

The tour celebrates a major milestone for the band's core members, who are turning 60 this year. Formed in 1987 in Hirosaki, Aomori Prefecture, Ningen Isu (Human Chair) has built a devoted following with their unique blend of heavy metal and traditional Japanese literary themes.

The band takes their name from a short story by mystery writer Edogawa Ranpo and is known for incorporating classical Japanese literature into their lyrics. Their theatrical style and horror-influenced imagery have made them cult favorites both domestically and internationally, especially after gaining viral attention online in recent years.

While specific venues and dates haven't been detailed yet, the tour promises to showcase why Ningen Isu remains one of Japan's most distinctive metal acts after nearly four decades. The "Ryouki Shinsei" tour title suggests fans can expect the band's signature mix of literary horror themes and crushing riffs.

For a band that has consistently defied expectations throughout their career, this 60th birthday celebration tour represents both a look back at their legacy and a statement that they're far from slowing down. Ningen Isu continues to prove that age is just a number when it comes to delivering powerful metal performances.
