Professor Yoshiyuki Sanaki, an engineering professor at Tsukuba University, developed the hybrid assistive limb (HAL... nothing to do with that Arthur C. Clarke story) device that helps older citizens and physically disabled people complete tasks.  Takeshi Matsumoto, a 28-year old physiotherapist, will wear a specifically designed HAL suit that will allow his friend Seiji Uchida to be carried on Matsumoto's back.  The suit is battery-powered and works by detecting electric signals from muscle movement and will subsequently increase strength and stamina of the person wearing it.  According to the Daily Yomiuri:

Uchida broke his neck in a traffic accident in 1983, leaving him paralyzed. While hospitalized for more than three years following the accident, a distraught Uchida happened to see a picture of the Matterhorn reflected on the surface of a lake. He decided that one day he would visit the spot where the photo was taken.

Kyoga Ide, a 16-year old with muscular dystrophy will also make the journey along with Uchida.  They'll take a cable car up the mountain before making an attempt to get to the peak of the Breithorn.
