At a Glance
Key points
- 3 lobsters, a mix of extra-large and large, totaling 1.2kg. This is the only size offered. The shop’s guide to the amount is 6–7 servings. The page says individual lobsters vary, so the weight changes slightly
- A shell-on frozen product labeled for sashimi. The product name says “ikejime frozen” (killed live and frozen), “for sashimi” and “for raw eating” (the shop’s labeling). Thawing under running water is what the page instructs
- An eating guide sheet and 1 work glove (one hand) are included. The sheet describes how to prepare and cook the lobster. The page says each lobster is wrapped individually (an image in the product description)
- Rakuten rating 4.78 (179 reviews). 143 reviews are 5★, and there are 0 reviews at 1★ or 2★ (viewed October 18, 2026)
Watch out for
- The sizes of the 3 lobsters can differ (2 of the four 3★ reviews mention a difference in size or a lower weight. This is a trend within the Rakuten reviews we read)
- Because it is shell-on, you have to prepare it yourself (4 of the first 60 reviews in the default order say it was hard work. This is a trend within what we read)
The features are from the Rakuten Ichiba product page (viewed October 18, 2026). The rating is as shown on Rakuten and may not represent the current state of the product.

Summary: Is This the One for You?
Why choose it: If your conditions are to receive 3 shell-on ise-ebi labeled for sashimi in one order, and to have an eating guide sheet and a glove as well, this product is a fit.
- 3 lobsters, an extra-large and large mix, totaling 1.2kg. The amount is described as 6–7 servings
- An eating guide sheet and a work glove (one hand) are included, and each lobster arrives wrapped individually
- The Rakuten rating is 4.78 / 5 (179 reviews). Among the 64 we read, many voices mention sashimi (about 20) and size (about 20)
The weak points are that the sizes of the 3 lobsters can differ, and that being shell-on means you have to prepare it yourself.
Other options: If you want to try shrimp from an amount of 500g, there is ますよね Roe-Bearing Echizen Sweet Shrimp 500g (500g).
