Even when long-life water is labeled “5 years,” the product page alone can leave questions: how many liters 24 bottles actually add up to, where the best-before date is printed, and whether the water can be kept in the box it arrives in. This article organizes the publicly available product information and review-site entries for the “5-Year Long-Life Water” (志布志の自然水 5年保存水, Shibushi Natural Water) 500ml × 24 bottles, sold on Rakuten Ichiba by ICSselection-イクスセレクション- and described as water drawn in Shibushi City, Kagoshima Prefecture, into five points: content volume, shelf life, ingredient labeling, suitability as a gift, and reviews.
What We Confirmed
- Content volume and a guide to servings
- Storage method and shelf life

Ingredients and Allergen Labeling
The ingredient is stated as “water (spring water).” For nutrition facts, the “Nutrition facts (per 100ml)” section of the product description states 0 for energy, protein, fat and carbohydrate, and sodium 13mg, calcium 1.1mg, potassium 0.54mg and magnesium 0.29mg. The heading of the same field also contains the words “per 1000ml,” so the notation of which amount the figures refer to is inconsistent. In this article, the figures are transcribed according to the “per 100ml” notation attached to the names of the figures. The page also states hardness 38mg/L (soft water), silica content 82.0mg/L and pH 6.7 (20.2°C) (Source: Rakuten Ichiba product page, accessed October 13, 2026).
The product name shown on the Rakuten Ichiba product page includes a phrase about water-quality testing (“PFAS 水質検査適合,” meaning PFAS water-quality test compliant). The testing body, date and results are not found on the product page, and this article has not verified the content (Not confirmed).
Within what we could check, the product page has no dedicated allergen labeling. This item is Not confirmed. If you are concerned about allergies, please ask the shop before buying or check the food information label on the product you receive.

Five Things to Check Before Buying
| Item to check | This product | Basis |
|---|---|---|
| 1. Content volume / servings | 24 × 500ml bottles (12L in total). The number of servings is not stated | Description field of the product page. No statement on the number of servings |
| 2. Storage method and shelf life | Store in a cool, dark place out of direct sunlight, in the box, according to the page. The product name carries the labeling “賞味期限 5年以上” (best-before date of 5 years or more) (the specific date: Not confirmed; it is stated to be printed on the side of the box) | Description field and product name on the product page |
| 3. Ingredients and allergen labeling | The ingredient is water (spring water). Dedicated allergen labeling: Not confirmed | Checked the Rakuten Ichiba product page |
| 4. Whether it works as a gift | The page states that wrapping and noshi (gift wrapping label) are not supported | Description field of the product page |
| 5. Trends in reviews | The Rakuten Ichiba rating is 4.72 / 5 (524 reviews). We read the first 60 reviews in the default order of Rakuten Minna no Review (posted November 2024 to September 2026; latest September 2026), plus all 2 reviews rated 1★, all 1 review rated 2★ and all 16 reviews rated 3★ (posted September 2013 to February 2026), 79 in total. Many reviewers bought it for stockpiling and have not yet drunk it, while some who drank a previously bought batch when replacing it wrote that it was easy to drink or tasty. Some posts also mention that the bottle shape has changed from before. This trend may not reflect the product’s current condition. The points are organized by theme in the “What Public Reviews Say” section | Rakuten Minna no Review (accessed October 13, 2026) |
Suitable as a Gift?
The product description states that wrapping and noshi (gift wrapping label) are not supported, and that choosing wrapping on the order screen results in cancellation. Because drinking water is delivered with the shipping label attached directly to the outer case, a gift sent to the recipient would also arrive as a bare outer box without wrapping. If you are considering it as a gift, checking the following points before buying helps avoid misunderstandings.
- That noshi and wrapping are not available (stated on the product page)
- Whether the recipient can receive a parcel of about 13kg per case
- Whether the recipient has space for a box of 256mm × 376mm × 220mm
Among the reviews we read, we found no post saying the buyer used it as a gift (Source: Rakuten Minna no Review, accessed October 13, 2026). The uses stated on the product page include disaster preparedness and stockpiling.

Rating breakdown: 5★ 403 / 4★ 102 / 3★ 16 / 2★ 1 / 1★ 2 (as shown on Rakuten Ichiba, viewed October 13, 2026)

Among the 60 reviews in the default order, many were written by buyers who bought it for stockpiling and have not yet drunk it. The 3 reviews rated 1★ or 2★ each mentioned one of the following: how the delivery was handled, the taste, or a box that arrived already opened (1 review each; all posted in 2021 or earlier). These are trends within what we read and may not reflect the product’s current condition.
What Reviewers Praise
Reassuring as a supply because it keeps for 5 years
17 of the 60 reviews in the default order wrote that with a 5-year best-before date it can be kept on hand as a supply, and that when the date comes you can use it and buy again.
Easy to drink when it was drunk at replacement time
7 of the 60 reviews wrote that they drank a previously bought batch when it was time to replace it and found it easy to drink or tasty. Many reviewers have not yet drunk it, and the number of posts that describe taste is not large.
500ml is easy to carry out and use daily
5 of the 60 reviews mentioned that 2L bottles are heavy to carry, while 500ml is easier to take out or use in daily life.
Easy to store in the box
4 of the 60 reviews mentioned that it comes in a sturdy cardboard box and can be stored as it is, and that the best-before date is printed on the outer box, which makes storage easy.

What Reviewers Note
The bottle shape changed from before
2 of the 60 reviews in the default order (November 2024 and April 2026) mentioned that the shape or size of the bottle had changed from before, and that it went from square to round and became harder to store. Some posts also say the volume is the same. The shape of the bottle that will arrive could not be confirmed from the photos on the product page (Not confirmed).
Posts that mention price
2 of the 16 reviews rated 3★ (November 2018 and June 2021) mentioned the price of the 500ml case. Both wrote that they bought it citing the fact that it keeps for 5 years or its portable size. There are no posts from the last two years.

Summary
- 24 × 500ml bottles (12L in total). For storage space, use the stated box size (256mm × 376mm × 220mm, about 13kg) as a guide
- Store it in its box in a cool, dark place out of direct sunlight. The product name carries the labeling “賞味期限 5年以上” (best-before date of 5 years or more), but we could not confirm the specific date of the item you receive on the product page (it is stated to be printed on the side of the box)
- Many reviewers bought it for stockpiling and have not yet drunk it, so there is little information on taste. Because the page states that wrapping and noshi are not supported, anyone considering it as a gift should keep in mind that it arrives as a bare outer box without wrapping
