Mystery Item Shop locations
The hidden Mystery Shops contain Stat boosting items, secret Ability Books, and special Accessories that you normally can't get through regular game play. Some of the entrances to these shops require you to have the Jetpack Item, which is purchasable in the Yokohama Mystery Shop or obtainable as a reward for the Nizaemon Bounty Job.

There is one shop in each district:

IKEBUKURO - Equip the Jetpack Item and jump on the vending machine that is located in front of the bookshop. Double jump to the top of the building, run across the arch to the right, and make your way to the top of the Tech Burger building. Walk all the way to the right until you hit the wall, then hold up until you enter the shop.

SHINJUKU - Head right one screen from the Train Station, take a few steps to the right of Tech Burger, and you should see a half-open door on the bottom of the slope. Press up on the door to go inside.

YOKOHAMA - Walk two screens to the right from the Train Station and you will see a crack on the outside of the warehouse. Simply walk into it.

UENO - Either walk two screens to the left or to the right from the Train Station until you reach Ueno Park. Walk towards the top left section of the map until you see a statue. Walk into it to find the shop.

SHIBUYA - Go left one screen from the Train Station and walk to the front of the restaurant. Equip the Jetpack Item and jump onto the orange awnings and then double jump to the top of the building. Then go all the way to the left until you hit a dead end. Then hold up until you enter the shop.

ASAKUSA - Head right and walk past the base of the escalator until you're in front of the green arrow sign on the wall. The sign IS the door so hold up to walk in.

AKIHABARA - Head a couple of screens to the right until you're in the last room, which is the 2nd floor of the Electronic Store. There should be a big flat screen TV with a talk show on it. Walk into it.

SHINAGAWA - Go left one screen from the Train Station and keep walking until you see the bottomless pit. There is actually a bright yellow-orange ladder in the middle of the pit to clue you in that the shop is there. Align yourself very carefully with the ladder and hold down until you enter the shop. It is very easy to be off by one pixel and fall to your death, so take extra caution and save right before you attempt it.
