About this product
The OK Prostate Chip is a small device that is placed in the urethra (the urine passage) so that it acts on the prostate; the maker sells it in several shapes, sizes and materials. It is made and sold by OK Lab (Okada Comfortable Life Laboratory), a small company in Japan, through its own online store, and prices are in Japanese yen (JPY). The maker's development diary, "ok-lab's diary", is written in Japanese. This page is an English summary of it, and every quotation is translated. OK Lab ships internationally, so readers outside Japan can order (see "Buying from outside Japan" below). Product names on this page are plain-English descriptions. The official Japanese product name is shown once in the product table so you can find the same item in the store.
Before you read: key terms
| Term | Plain-English meaning |
|---|---|
| Urethra | The urine passage; the maker places the base device here for prostate stimulation. |
| Version number | A number distinguishing designs; the customer used it to mark changes in the custom chip series' underlying ideas. |
| Bent connection | A curved link joining chip parts; it sets their positions relative to each other. |
| Milking | The diary's term for moving a small chip along a flexible tube; it described the proposed device's capability. |
| Rubber joint | A flexible connection between chip parts; its rounded form also became part of a nickname's explanation. |
| Chipless | The diary does not explain this. It uses this label for a larger device considered for anal and vaginal uses. |
What happens: OK Prostate Chip names
The OK Prostate Chip is a small device placed in the urethra (the urine passage) for prostate stimulation. These entries explain names for whole designs, individual parts, and prototypes. Some parts were intended for the urethra or bladder. A later design covered possible anal and vaginal uses, according to Mr. Okada. The names reflect customer ideas, his impressions, and changing plans for those devices.
Custom chip names could belong to a customer's whole design
In entries published in November 2020, a customer sought a custom chip (Sea Slug), requiring version 5 to work or reverting to modified version 4. Mr. Okada proposed defining version 5 through the second piece's shape, connection position, and angle, using a choice of existing leading pieces. Respecting the customer's design concept, Mr. Okada withdrew his entire naming proposal and reserved the name for the complete design.
He said OK Lab could sell the parts in its own products if rejected, but would not use the customer's series name. The diary does not record whether testing met the customer's expectations. No matching product can be confirmed on the current list.

Sea Slug chip connections needed rebuilding after a rubber bonding problem
In an entry published in December 2020, Mr. Okada reported a problem with bent connections (curved links joining chip parts). He attributed it to adding fresh rubber over rubber that had already hardened. He said every affected connection had been remade, including the custom version 5 design discussed in November 2020.
The photographed group contained four connections, each with a connection length of about 2-3mm. The diary does not record how the remade connections performed for their customers.

Mr. Okada reported bleeding during an Apple Alien chip prototype test
In an entry published in January 2026, Mr. Okada described testing a jointed prototype (Apple Alien), labeled prototype 1, a New Year special. He reported a small amount of bleeding after forcing the prototype, which had not bent as expected. He wrote that he had pushed ahead because he wanted material for the blog, despite not feeling ready to try it.
He suspected friction, but the entry does not record a medical assessment of the episode. He described a faint trace of blood on the chip and little further bleeding. No matching product can be confirmed on the current list.

Formal chip names stayed descriptive while internal nicknames became deliberately coarse
In an entry published in February 2026, Mr. Okada separated his planned formal product names from the nicknames used inside OK Lab. The formal descriptions identified an easier-bending movable chip and a long movable chip. For internal conversation, he wanted coarser versions of those names with a swear word added for emphasis.
He linked that mood to his enthusiasm for a poet's work and described making the long version partly for fun. No matching product can be confirmed on the current list.

The maker's answer to OK Prostate Chip names
Mr. Okada's naming choices followed intended scope, personal impressions, and names he found easy to say.
Early chip names broadened when medical device questions stalled sales
In an entry published in October 2017, Mr. Okada said advice about possible medical device requirements had temporarily stalled the sales plan. The concern involved selling a chip for urethral cleaning, and he had not resolved the legal question. He could not settle on a purpose-specific name, fearing that medical device classification might prevent his company from selling the product.
He considered selling a small chip movable by milking (movement along a flexible tube), without limiting its purpose. A reader's suggested name describing that movement became his leading candidate. Mr. Okada favored the broad description while acknowledging that he had not investigated the law in detail.

The Lock-on chip name reflected personal impressions after limited testing
In an entry published in August 2024, Mr. Okada described a looped cord chip (Lock-on) named after his personal impression during use. He usually relied on spontaneous ideas or wordplay, but said this name reflected a feeling of firm contact around the prostate. He considered alternatives suggesting holding or a key lock, drawing partly on the chip's keyholder-like form.
However, he reported only about 1 day of testing and said his own test conditions might differ from other uses. He explicitly said he was not yet ready to recommend it actively. No matching product can be confirmed on the current list.

A larger chip name left room for uses beyond prostate stimulation
In an entry published in July 2025, Mr. Okada described a prototype initially intended for anal use. He chose a broader name for the large chipless device (Big Size Chipless), because he also imagined it being used for vaginal exercises. He therefore decided against defining it solely as a prostate massager intended to act through the anus.
These were his proposed uses; the paragraph does not record customer testing of them. No matching product can be confirmed on the current list.

The Apple chip nickname survived changes to its original namesake
In an entry published in January 2026, Mr. Okada explained why the jointed prototype's Apple nickname no longer depended on its original tip. He had previously linked it to a miniature-apple feature on the resin leading piece. A ceramic leading piece had now appeared without that feature, leaving the earlier explanation incomplete.
He extended the miniature-apple description to the rounded rubber joint (the flexible connection between parts). He attributed that rounded form to how the rubber settled naturally. Mr. Okada preferred an easy name such as Apple to a longer technical name about remembering a shape.

Common worries about OK Prostate Chip names
Readers raised questions about design feasibility, a smoother component, and a cuter name for bumps.
"Could the Sea Slug chip be made safely?"
In an entry published in November 2020, the customer asked whether the proposed custom design was feasible and could meet their safety concerns. Mr. Okada agreed to explore it, although the suggested benefit of placing the leading piece entirely inside the bladder did not convince him. He used a 40mm leading piece from an earlier version because its length matched the request.
He warned that a bent connection at 90 degrees was difficult to make and would probably raise the processing price. No amount was quoted, and the diary does not record the final charge. He planned a ceramic second piece only if his own testing of the resin prototype found no problems.

"Could the Sea Slug chip have a smooth leading piece?"
In an entry published in November 2020, the customer requested a smooth leading piece to test the second piece's contribution. They preferred a shape intended to reduce strain on the bladder and left its exact design to Mr. Okada. He accepted the change and described the resulting form as unlike any of his previous products.
He also thought the plain shape improved safety for placement in the bladder, while acknowledging concerns about pressure on delicate structures. That was his assessment of the design; the entry does not record completed testing confirming the customer's hoped-for effect. He planned to prepare a ceramic mold once the customer approved the prototype.

"Could the bumpy chip name sound cuter?"
In an entry published in December 2020, Mr. Okada reported a reader's suggestion that the bumpy chip feature deserved a cuter name. He acknowledged finding the existing wording clumsy and said he had struggled with the choice.
Several alternatives had been suggested, although the paragraph did not list them. He decided to retain the awkward name because, in his view, sexual desire was basic rather than refined.
