The Kirei from Hirotaka Matsui is a new toilet designed to make
cleaning the bathroom a little less disgusting. The toilet
cleans and sterilizes itself, which means that only the sink and
tub are left to give you trouble.  Kirei has a self-cleaning
feature can be set automatically or controlled via remote
control or a wall-mounted control system. When the lid is
closed, the toilet's sterilizing lamp comes on to ensure that
the seat is germ-free for the next user. While the toilet is
performing these functions, LED lights come on to inform the
user that it is working, creating a glowing toilet that looks
pretty darn good from a design point of view. You can check out
conceptual images of the Kirei from Hirotaka Matsui here, along
with a ton of other innovative and creative toilet designs.
