Tak Matsumoto
A closed memorial service was held on June 26 at a funeral hall in Aoyama, Tokyo for members of the entertainment industry. This was attended by celebrities such as Maki Ohguro (another female vocalist who, like Sakai, rarely appears in public and writes most of her own material and like Sakai; a phantom singer). Almost as if to illustrate Sakai's impact on the Japanese music scene and the depth of her presence, singers Tak Matsumoto and Koshi Inaba, members of the popular B'z group, pop-singer Mai Kuraki, and even baseball giant Shigeo Nagashima all left moving messages of their encounters with Sakai. Singers Hikaru Utada and Nanase Aikawa, though not personally acquainted with Sakai, also issued memorial statements on their official web pages, describing how Sakai's death had shocked them.
