I discovered that I love raw fish. I'm planning to buy a sushi-grade fish to make myself a sashimi or poke but I wonder if there is method of bringing it for lunch to work after preparing it day before.
Is it possible to store a prepared raw fish (poke/sushi) in fridge/freezer overnight or is this a safety hazard and it needs to be eaten soon after preparation which includes thawing.
EDIT I mean fridge at home then at work. I live 5-10 minutes from work so if isolated it should not change temperature significantly, I think.

You're never going to remove all of the risk, but the standard recommendation for keeping raw fish for a day is placed on crushed ice, and kept in a fridge.
As the ice will melt, you also need to make sure that the fish won't end up sitting in water. So, what you want to do:
For Poke, I'd place it into a sealable plastic container that would loosely fit into another sealable container, so that you can pack crushed ice between the two. Ideally, I'd look for an insulated tiffan-like container (wide mouth thermos, sometimes sold as a 'bento jar'), and then:
You might want to look for poke recipes that are especially salty, as it will act as a preservative. If there's any acid in it, you may want to wait to add it just before eating, so you don't end up with ceviche.
