The “Kani Jumbo Fukubukuro” (Crab Lucky Bag) lets you choose one of three categories at purchase — “生かに福袋” (Raw Crab), “たらばがに福袋” (King Crab), or “ボイルかに福袋” (Boiled Crab) — but which specific item you actually receive within that category is not determined until your order is processed. It’s a lottery-style (gacha/lucky-draw) product. This article organizes, from the product page’s own listing, the candidate items and allocation odds for each fukubukuro category, their price ranges, and the publicly available reviews — on the understanding that the exact contents are not fixed at the time of purchase.
This product is a lottery-style item. The specific item you receive is not fixed at the time of purchase. Which item within each category you are sent is assigned automatically by a program, based on the allocation odds shown below (your own preferences or past order history are not taken into account).

How the Lottery Works
The product page describes the allocation mechanism as follows:
“Items are allocated automatically and fairly by a program, following the allocation odds shown on this page at the time of purchase, with no human involvement. Concurrent or past order history, and any individual requests from customers, do not affect item allocation. Because allocation is performed per order, the proportion of items allocated so far will theoretically converge toward the stated odds over time, but the proportion allocated at any given moment is not guaranteed to match the stated odds exactly.”
“‘Fukubukuro’ here is a conceptual term meaning ‘you don’t know what you’ll receive until you order’ — it does not mean the item is physically wrapped in a bag that conceals its contents.”

In other words, at the time of purchase you can only choose the category — “Raw,” “King Crab,” or “Boiled” — and you cannot choose which item (size, quantity, or cut) within that category you’ll receive. Below, we organize the candidate items and allocation odds for each category exactly as shown on the product page. Note that the King Crab Fukubukuro includes both raw and boiled items among its candidates. Since the odds can change, please check the product page for the latest figures before purchasing.
