Name
Rectangular Box. Sorry for such a lousy working name, but I couldn't think of anything else which will not give any clues away. Name to be confirmed.

Designer
Hideaki Kawashima

Type & Classification
Trick Opening Puzzle Box

Dimensions
11cm x 6cm x 6cm

Materials & Construction
There's a bit of purpleheart here and there but I can't really tell what is the wood used for the overall build. More information once the solution/specs are sent to me early 2016. Construction fit and finish is excellent with nice detailing and everything slides smoothly as intended. 

Overview
To find the hidden compartment. A whopping 16 moves (thanks to Brett and Oli for highlighting this to me; I had missed the last 4 steps) required to solve the puzzle completely.

Difficulty Level
Moderately difficult, by far the most challenging, compared to the previous 5 presents.

Summary
This is my first puzzle by Kawashima. A rather unusual puzzle box with quite a number of moves by Karakuri Christmas Presents standard. Quite a fair bit to do here. Very tricky to the last and requires careful observation to get the moves right. Got me stumped for a while. IMHO, this is the level of difficulty appropriate for a Christmas present, not easy yet sufficiently difficult to let puzzlers feel they are really getting puzzling value for money.
