The Wii U Does Not Come with a Sensor Bar (in Japan)

The Wii came with a Sensor Bar. The Wii U does not. The logic behind this seems to be that Nintendo thinks Wii U customers already have a Wii, so they can use that Sensor Bar with the Wii U.

Those customers who do not have a Sensor Bar, Nintendo is more than happy to sell them one for ¥2,030.
