If anyone can find one that measures over seven meters (22.96 feet), then, yes, this is the longest hug pillow on Earth.
Note: One of the images below *might* be NSFW.
The hug pillow features the human-snake lady Miia from Monster Musume, a manga and anime about monster girls. The pillow is one-to-one scale with the actual character!
These images should give you an idea of the pillow's length.
Going on sale at this month's Comic Market in Tokyo, the limited edition pillow case features an illustration drawn by Monster Musume creator Okayado, and was priced at 100,000 yen ($1100). Yes, just the case.
