Utada United 2006 was a Japanese concert tour by Japanese-American singer-songwriter Hikaru Utada. It was Utada's second concert tour of Japan following their Bohemian Summer 2000 tour. A live DVD of the tour was released on December 20, 2006.
During the filmed concert, Utada wore four different outfits. The first outfit worn was a long, tattered, black and white outfit with pieces of cloth that hung a little above their ankles. Near the shoulders, this dress seemed to puff out, or become feather-like. They sang their first seven songs in this outfit. Then they wore a leather-like coat, that resembled a ballroom gown from the waist down. Utada sang their Exodus songs in this dress. When looked at closely, you can see that underneath it was the next outfit, which was a red dress. It had strips near the shoulders, and allowed them to move more; a feature which was helpful in performances like "Can You Keep a Secret?" and "Wait & See ~Risk~". They sang the next eight songs in this particular outfit. The last outfit, which was very light compared to the rest, had a small blue skirt and a light pink top. In this outfit, they sang their last two songs, "Automatic" and "Hikari".
In some of early performances, they substituted the pink top with a black blouse. Underneath all of the outfits was a black sleeve-less leotard and black knee high boots with wedge heels.
The concerts at the Saitama Super Arena attracted about 18,000 spectators each.
