Among the delivery posts, ★1 reviews from December 2023 and December 2025 said it did not arrive on the specified date. Year-end is a busy order period, so if you have a set date to use it, it is safer to leave some extra days.

Summary: Is This the One for You?

Why choose it: You want a roast pork you can keep in the freezer, and you want one you can serve just by slicing after thawing. If those two are your conditions, this product fits.

  1. The best-before date is 300 days from the manufacturing date, and the page says it is delivered with at least 30 days remaining. Storage is described as frozen
  2. Thawing is described as about 24 hours in the refrigerator. After thawing, the page says to take it out of the bag and slice it to the thickness you like, and about 9 reviews mentioned serving it on salads or sliced thin
  3. Rated 4.72 / 5 on Rakuten (2,727 reviews). About 19 of the 59 reviews we read in the default order said it is tender and moist. However, about 21 of the 57 ★1 and ★2 reviews said it is strongly salted or peppery, so it may not suit people who want to decide the seasoning themselves
