Arashi (Japanese word for storm), is a Japanese popular group consisting of five boys from the Johnny & Associates stable.

They made their sudden debut in September 1999 in Honolulu, Hawaii. The group has been signed under the Pony Canyon record label from 1999-2001, producing their first singles (A-RA-SHI to Jidai) and their first album, ARASHI ICHIGOU: Arashi wa Arashi wo Yobu before they transitioned forward to Johnny's-powered J-STORM record label in 2002, producing their future singles and future albums until today.

The group members are:
• Aiba Masaki (b. Dec. 24, 1982)

• Ninomiya Kazunari (b. June 17, 1983)
• Ohno Satoshi (b. Nov. 26, 1980)
• Sho Sakurai (b. Jan.25, 1982)

This group is widely known for the members' good looks and for the group's smartly executed, powerful dances. The fans' ages range from the low teens up to the mid-forties.

On the day of their debut single "A·RA·SHI", more than 80,000 fans showed up to attend their debut event. Since the debut single, the group has released more than 10 singles, including "Hadashi No Mirai (The Barefooted Future)" and "Jidai (Generation)" and 4 albums in the hit chart including their first single collection album.

Their first four singles, "ARASHI (Storm)", "Sunrise Nippon (Sunrise Japan)/HORIZON", "Typhoon Generation", and "Kansha Kangeki Ame Arashi" attracted many people because they all dealt with nature. The cheap cost of 500 yen also attracted people to buy their 7th, 8th, and 9th singles. Arashi's produces a wide range of different types of music, including rap, house, and hip hop. In 2002, Arashi established a music company of their own called J-Storm.

Arashi has also been taking part in various dramas, variety shows, TV commercials, and movies.

The entire group played the lead in the drama called "V No Arashi (Arashi of Victory)" that supported the Japanese volleyball team in the World Cup. Other dramas include "Gokusen" (Gangster Teacher), "Hana Yori Dango" (Boys over Flowers), and "Kimi Wa Petto" (You're A Pet) by Matsumoto, "Kisarazu Cat's Eye" and "Yoiko No Mikata (A Friend of Good Kids)" by Sakurai, "Stand Up!" by Ninomiya, and "Yankee Bokou Ni Kaeru (A Yankee Goes Back to His Alma Mater) by Aiba. The group took part in their famous movie, "PIKA*NCHI~Life is Hard Dakara(so) Happy" and "PIKA**NCHI Double" that concerned the passionate youth of 5 boys, acted by members of Arashi.

Arashi's performances as the post-SMAP Johnny's group can be expected in the future and will catch people in the "storm" of excitement.
