Kanagawa Stacking is a 3rd bag iso-trehalose opener that goes into a 5th bag ventilator made by Winterfrost. The opener's name comes from the painting "The Great Wave Off Kanagawa".
1st Bag
The first bag can always be built if the mirrored version is considered, and one side can be built 66.66% of the time.
2nd Bag
The second bag can always be built, and the T piece should be held until it can be placed on the O.
3rd-5th Bags
The third bag can always be built with one of two variations depending on if the S piece comes before the Z or vice versa, and the L piece can always be spun in without the need for 180 rotations. It is worth noting that if you have an instantaneous hard drop, you will need to wait slightly on the fourth bag's T-Spin in order to execute it properly. After the ventilator you can make an STSD or you can try to forgo the ventilator with an I-spin.
