Masato Hayakawa

Coldrain would start to gain more traction after a couple of their songs, "8AM" and "We’re Not Alone", would be used as opening themes for animes such as Hajime No Ippo: Challenger and Rainbow: Nisha Rokubō no Shichinin. Another would receive worldwide fame upon being released as a part of the soundtrack for Pro Evolution Soccer 2011, called "Die Tomorrow" and as such would become a staple song for the band. The latter two songs were used on their debut EP, Nothing Lasts Forever, released in the summer of 2010.

Hayakawa married Japanese-Australian model, Hanna Kelk, on October 24, 2019.

At the tail end of 2018, they would release a new single “Revolution", which would be a tie-in to be the main theme of Gundam: Extreme Vs 2. This tease would lead to speculation of a new album which was later released as The Side Effects in August 2019. This included other singles such as "Coexist", "January 1st" and the title track. However, the song which elevated the band to new heights was “Mayday” that featured Ryo of fellow Japanese metalcore band Crystal Lake. This song would end up becoming the opening theme for the popular anime Fire Force.

2017 would mark Coldrain's 10th anniversary as a band. To coincide with this milestone, they released their fifth studio album Fateless, in October of the same year, as well as a tour that would end with them playing at the famous Nippon Budokan venue. Their performance at Budokan in February 2018 would eventually be released as a DVD/Blu-ray.

Vena would be the first album to be released worldwide at its initial release. It would feature lead singles such as "Gone" and "Wrong", as well as a feature from Papa Roach frontman Jacoby Shaddix on "Runaway". Coldrain would go on several headline tours in 2016, including playing at the Vans Warped Tour in the summer. During this time, they would release their third maxi-single for the first time since 2009. This was released as Vena: Chapter 2, and featured two new tracks, as well as acoustics of "Gone" and "The Story".

Coldrain would release two follow up studio albums, The Enemy Inside and The Revelation. The latter would end up being released worldwide in 2014 as a reissue, including new songs from their Japanese exclusive EP Until The End, following being signed to the North American-based label Hopeless Records that is home to bands such as All Time Low, Avenged Sevenfold and Silverstein. This would allow them to tour all around the world with bands such as Bullet for My Valentine and Papa Roach, as well as playing festivals in Europe such as Download and Rock am Ring.

The first song that they ever recorded was "Painting", along with two maxi-singles, Fiction and 8AM, that they would hand demos of out on the streets to help spread their music through the word of mouth and play gigs in high school gyms and clubs starting out. Some of these songs would end up being included on their debut studio album, Final Destination, which was released in the backend of 2009.

Coldrain would form in 2007 with Hayakawa as the vocalist, Y.K.C. and Sugi as the guitarists, RxYxO as the bassist, and Katsuma as the drummer.

In around 2003, Hayakawa met Katsuma Minatani in high school. A few years later, the two would start a band together as friends, forming AVER in the process. Hayakawa was the vocalist as well as the guitarist, while Katsuma was the drummer. They would produce songs such as “Voices Over Bullets” and regularly played gigs in clubs around their hometown of Nagoya.

It wasn't until the Nu-metal craze in 1999 where Hayakawa started to get into heavier bands, citing this as a critical point of his life which would end up helping him carving his career path. Limp Bizkit and Korn would be the first bands that he laid his eyes on while watching MTV as a teenager, with songs like "Nookie" and "Freak on a Leash" on constant rotation.
