Mainichi reports that Nintendo’s 3D-touting portable has reached more than one million in domestic sales for the Nintendo 3DS. Worldwide sales of the Nintendo 3DS have reached 3.61 million units (as of April 2011).

Recalling the DS line’s successful history, this is rather disappointing considering that the original DS reached this mark on it’s first month in the market while the DS lite and DSi took eight weeks each. Of course that is if you don’t consider the DSi LL (or DSi XL for us English speaking folks) as a different system which took 25 weeks to reach the 1M milestone.

The slow sale of the 3DS can be attributed to the lackluster release line up, the Japan Quake and the price.

Now if the price of the 3DS is still too steep for you, you may want to take a look at the DS lite, it’s just $99.
