Okamoto 002, Okamoto 003 and Sagami Original 002: What the Numbers on the Box Mean
By the OOBiz product information team. Reviewed on November 8, 2026.
Okamoto and Sagami put a number on the front of their boxes: 002, 0.02 or 003. This page explains what that number tells you and what it does not, for the Okamoto 002, Okamoto 003 Hyaluronic Acid and Sagami Original 002 boxes we sell. They are Japanese retail boxes imported from Japan. Every figure comes from the maker's box or the maker's own product page, and the sources are listed at the end with the date we checked them.
The short answer
- On these boxes, the number is the maker's own thickness figure. Okamoto 002 is the 0.02 mm class and Okamoto 003 is the 0.03 mm class; Sagami Original 002 is printed as 0.02 mm.
- It is the maker's own measurement, not an exact figure for every condom. Okamoto prints "0.02ミリ台", which means a thickness in the 0.02 mm range, measured by the company. Sagami prints 0.02 mm as its own measurement and states its standard thickness for Original 002 as 24 microns (0.024 mm).
- The number does not tell you the material. Okamoto 002 and Sagami Original 002 are polyurethane. Okamoto 003 Hyaluronic Acid is natural rubber latex.
How each maker words the thickness
Okamoto. The 002 box and Okamoto's product pages give the thickness as "0.02ミリ台". The character 台 means "in the range of", so the figure reads as 0.02-something millimeters, measured by the maker. The 003 Hyaluronic Acid box uses the same wording with 0.03.
Sagami. The Original 002 box prints 0.02 mm with a note that it is the company's own measurement. The front of the box adds a second figure: the company's standard thickness for this product, 24 microns. In other words, "002" is the series name, and 24 microns is the maker's stated standard for the box.
We treat the number as the name of a series, not as a measurement of each individual condom.
Material is a separate question
| Box | Material, as the maker states it | Japanese wording on the box or maker's page |
|---|---|---|
| Okamoto 002 | Water-based polyurethane. Not made with natural rubber latex. | 水系ポリウレタン |
| Sagami Original 002 | Polyurethane | ポリウレタン |
| Okamoto 003 Hyaluronic Acid | Natural rubber latex | 天然ゴムラテックス |
We also sell Okamoto 001 and Sagami Original 001 boxes. Both are polyurethane: Okamoto 001 is water-based polyurethane (水系ポリウレタン), labeled by Okamoto as 0.01 mm class, and Sagami Original 001 is polyurethane (ポリウレタン), with 18 microns stated as the maker's standard.
Okamoto 003 Hyaluronic Acid contains natural rubber latex, which may cause allergic reactions. Its lubricant is water-based with hyaluronic acid, and the box and Okamoto's product page state that the lubricant contains parabens.
With any latex condom, oil-based products such as petroleum jelly or body lotion can weaken the latex (CDC). For every box, follow the instructions on the leaflet inside.

The versions inside Okamoto 002
All four versions are the same water-based polyurethane, 0.02 mm class. What changes is size, shape or the amount of lubricant.
- Regular. The back of the box lists the size as Regular (レギュラー); the front calls the same box Standard (スタンダード).
- L (large). The box states that it is larger than the regular size of the series. Okamoto does not print a diameter or length in millimeters.
- Real Fit. A differently shaped version of 002. The box lists its size as Regular.
- Rich Lubricant (たっぷりゼリー). The box states that it carries 200% of the jelly lubricant of the Okamoto 002 Standard. Size Regular.
Okamoto 002 and Sagami Original 002 are different products
Both carry the 002 number and both are polyurethane, but they are different brands from different companies, and they are described differently. The Sagami Original 002 box gives a diameter of 36 mm and a length of 170 mm for the Regular size, and 38 mm and 190 mm for the L size. The Okamoto 002 boxes give no size figures. Sagami seals each condom in its own blister pack with the front side marked; Okamoto wraps each condom individually and marks the wrapper so you can tell which way it unrolls.
What the number does not tell you
- Size. Check the size label and any diameter or length the maker prints. Our size guide explains the terms: Japanese condom sizes: diameter, flat width and length.
- Pieces per box. It varies by version. On our store: 6 or 12 for Okamoto 002, 10 for Okamoto 003 Hyaluronic Acid, and 5, 10 or 20 for Sagami Original 002.
- Lubricant type. Of the boxes on this page, only Okamoto 003 Hyaluronic Acid describes its lubricant as water-based. The Okamoto 002 and Sagami Original 002 boxes state that the condoms are lubricated without naming a base.

Common questions
What is the difference between Okamoto 002 and Okamoto 003?
The number is the thickness class: Okamoto 002 is the 0.02 mm class and Okamoto 003 is the 0.03 mm class, both measured by Okamoto. The material also differs. Okamoto 002 is water-based polyurethane, and Okamoto 003 Hyaluronic Acid is natural rubber latex with a water-based hyaluronic acid lubricant.
Is a 002 condom exactly 0.02 mm thick?
The number names a series set by the maker, not an exact figure for every condom. Okamoto describes 002 as "0.02ミリ台", a thickness in the 0.02 mm range by its own measurement. Sagami prints 0.02 mm as its own measurement and states a standard thickness of 24 microns for Original 002.

Okamoto 002 is made from water-based polyurethane, not natural rubber latex.
Is Sagami Original 002 latex-free?

Does Okamoto 003 Hyaluronic Acid contain latex?
Yes. Okamoto 003 Hyaluronic Acid is made from natural rubber latex, which may cause allergic reactions. Its lubricant is water-based with hyaluronic acid, and the box states that the lubricant contains parabens.
Are Okamoto 002 and Sagami Original 002 the same?
No. They are different brands from different companies. Both are polyurethane and both carry the 002 number, but the Sagami Original 002 Regular box gives a diameter of 36 mm and a length of 170 mm, while the Okamoto 002 boxes give no size figures.
