Singer-songwriter Natsu Kai (the second daughter of rock musician Yoshihiro Kai) has announced the first ever highway rest stop tour. Kai releases her second single, "drive," on April 4. On the 6th, she begins her 3-day tour to promote the single, visiting six rest stops (also known as "service areas") on the Tomei Expressway. She will first perform in Shizuoka, then Aichi and Kanagawa.

Kai will travel in an ad-wrapped car, which she will drive herself. She currently has only a temporary license, so she will be aiming to get a permanent one by the end of the month.
