1. In a medium pot filled with enough water, bring to a boil on medium-high heat. Add chopped potatoes and eggs into the same pot to make it easier. Boil the potatoes for 10-15 minutes until fork tender. Hard boil the eggs for 9 minutes, then remove and transfer them into an ice bath. Once the eggs cool down, crack and peel them. Strain the potatoes in a colander.
2. To make the Potato Egg Mixture: In a large bowl, mash cooked potatoes, boiled eggs, salt and Japanese mayo together until well combined. Set aside.
3. To make the Crab Cabbage Mixture: In a large bowl, combine shredded cabbage, chopped imitation crab with Japanese mayo until well combined. Set aside.

Assemble Sandwich

1. For one sandwich: use 4 pieces of bread. Place a slice of bread on a clean working surface. Then spread a layer of the potato egg mixture on top of it.
2. Cover the potato egg layer with a slice of bread. Spread jam on top of that slice.
3. Place another piece of bread on top of the jam, spread the crab cabbage mixture on top and cover with another piece of bread.
4. Place a heavy plate on top of the sandwich to press it down or tightly wrap it in plastic wrap for 5 minutes.
5. Remove the plate or plastic wrap, slice off crusts on all four sides with a sharp serrated knife. Slice diagonally. Repeat the above steps for the remaining sandwich.
