King crab legs are shipped as a boiled, frozen product, so before buying it is hard to picture how much 800g actually is, or how soon you have to eat them once they are thawed. This article sets out what the Rakuten Ichiba product page and the publicly posted reviews say about the “King Crab Legs, legs only” sold by Gensen! Hokkaido Gourmet Kanisho (厳選!北海道グルメ かに匠) — you choose either 800g x 1 cluster or 800g x 2 clusters, where a “cluster” (kata, 肩) is the unit used for a set of king crab legs still joined at the shoulder. It is organised into five points: the amount included, storage and shelf life, ingredients and allergen labeling, whether it works as a gift, and what the reviews tend to say.
What We Confirmed
- How much is included, and whether the number of servings is stated
- Storage and shelf life, including after thawing
- Ingredients and allergen labeling
- Whether it works as a gift (noshi gift labels and wrapping)
- What the public reviews tend to say, and when those reviews were posted

Ingredients and Allergen Labeling
The ingredients given in the product description are two: king crab (product of Russia) and salt. However, within what we could check, the product page does not show the contents of the food information label (allergen labeling, including additives). This item is not confirmed.
This product is crab itself, so people with a shellfish allergy cannot eat it. Crab is one of the ingredients that must be declared under Japan’s Food Labeling Act. If someone in your household has a shellfish allergy, or if you want to check the additives used in processing, ask the shop before buying or check the food information label on the product when it arrives.

Suitable as a Gift?
The gift field on the Rakuten Ichiba product page showed that noshi (gift wrapping label) is available (checked 12 September 2026). However, we could not find any statement about the types of inscription on the noshi (such as oseibo year-end gift, ochugen mid-year gift, uchi-iwai return gift, or plain), gift wrapping or a gift box, message cards, or having a name printed. If you want to specify the inscription, check with the shop before ordering.
If you are considering it as a gift, here is what we could and could not confirm from the product page.
- Noshi: shown as available. The types of inscription are not confirmed
- Gift wrapping, gift box, message card and name printing: we could not find any statement
- The page states that nothing showing the price, such as an invoice, is enclosed
- It arrives by frozen delivery, so checking whether you can specify a delivery date and time the recipient can accept makes a missed delivery less likely
- For delivery to Okinawa Prefecture, the page states that an additional shipping charge applies (checked 12 September 2026)
- The product description states that broken legs may be included, so it may not suit a recipient for whom appearance matters

| Site | Rating | Number of reviews | Date viewed |
|---|---|---|---|
| Rakuten customer reviews (“Minna no Review”, product page) | 3.98 / 5 | 3,767 | 12 September 2026 |
The breakdown by star rating is 1,656 five-star, 1,155 four-star, 471 three-star, 204 two-star and 281 one-star reviews. The trends below summarise the first 30 reviews read in the order sorted by “most helpful”.
One thing to keep in mind: many of the posts shown at the top of the “most helpful” order date from around 2007 to 2015, and the most recent post was from December 2024 (as of 12 September 2026). Because older posts come to the top in this sort order, they do not necessarily reflect the product as it is now.

What Reviewers Praise
Posts about the amount and the contents stand out: that there is plenty of it and it is filling, and that the legs are well filled with meat. Some posts say that legs only makes it easy to eat, and that it worked for a wide range of dishes such as grilled crab and crab steak.

What Reviewers Note
Several posts point out that it tasted salty, and some say they soaked the crab to draw out the salt before eating. There are also posts saying that broken legs, or pieces that were not well filled with meat, were mixed in, and posts saying it was smaller than expected. Low ratings (one and two stars) come to 485 in total, so impressions vary.
