Weight is another important factor especially when deciding on a camera that you want to carry with you all day.
Nikon 1 J4 is significantly lighter (1248g ) than the Pentax 645D which may become a big advantage especially on long walking trips.
Also keep in mind that body weight is not the only deciding factor when comparing two interchangeable camera bodies, you have to also take into account the lenses that you will be using with these bodies. Since Pentax 645D has a Medium format sensor and Nikon 1 J4 has a smaller 1" sensor, Nikon 1 J4's lenses for a similar focal length and aperture will generally be lighter and smaller than the Pentax 645D lenses.

Weather Sealing
Thanks to the weather sealed body of 645D, you can use this camera with more confidence under conditions where there is risk of exposure to water and dust compared to 1 J4.
LCD Screen Size and Features
Nikon 1 J4 and Pentax 645D's LCD screens has the same diagonal size of 3".
Unfortunately, both cameras has fixed screens so they don't tilt or flip in directions.
Nikon 1 J4 has a 18.0MP 1" (13.2 x 8.8 mm ) sized CMOS sensor and features Expeed 4 processor. On the other hand, Pentax 645D has a 40.0MP Medium format (44 x 33 mm ) sized CCD sensor and features Prime II processor.
Pentax 645D's sensor provides 22MP more than Nikon 1 J4's sensor, which gives a significant advantage in real life. You can print your images larger or crop more freely.
On the other hand, please keep in mind that Max sensor resolution is not the only determinant of resolving power. Factors such as the optical elements, low pass filter, pixel size and sensor technology also affects the final resolution of the captured image.
One other difference between these two cameras that is worth mentioning is that Pentax 645D's sensor doesn't have an anti-alias (Low-Pass) filter. Removing anti-alias filter increases the sharpness and level of detail but at the same time, it increases the chance of moire occurring in certain scenes.

Sensor Size and Resolution Comparison image of Nikon 1 J4 and Pentax 645D Cameras
As seen above, Pentax 645D has a 12.5x Larger sensor area than Nikon 1 J4. Larger sensors give photographer more control on the depth of field and blurry background compared to smaller sensor when shot in same focal length and aperture.
Number of available lenses is a big decision factor while choosing your interchangeable lens camera. When we look at the available lenses for these two cameras, we see that Nikon 1 J4 has an advantage over Pentax 645D. There are 13 lenses for Nikon 1 J4's Nikon 1 mount, on the other hand there are only 6 lenses for Pentax 645D's Pentax 645AF2 lens mount.
Another important factor is the availability of image stabilization. None of these bodies have sensor based image stabilization so you have to buy lenses with Optical stabilization feature. Currently there are 7 lenses for Nikon 1 mount and 2 lenses for Pentax 645AF2 mount with IS.
