What is an OK Prostate Chip?

Published: 2026-09-07 / Updated: 2026-09-07

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. Prices are in Japanese yen (JPY).

The maker's founder, Mr. Okada, has written a weekly development diary in Japanese since 2009 (ok-lab's diary). This site summarizes that diary in English, topic by topic, so that readers outside Japan can follow what customers asked, what the maker answered, and how the products changed over time. Quotations are translated.

This site is not OK Lab's official site. It is an independent guide written from the diary, and it contains affiliate links.

How to use this site

• Browse by problem: pick the topic that matches your question (for example, a chip that will not go in, bleeding, cleaning).
• Product guide: see the current product list with the official Japanese names, so you can find the same item in the store.
• Ordering from outside Japan: the maker's shipping and payment terms for overseas orders.

Safety

If you see blood in your urine, even a small amount or for the first time, do not wait and see. See a urologist right away. If you suddenly cannot urinate, or the device cannot be removed, do not try to fix it yourself. Go to a medical facility, including emergency care, immediately.

The product is not a medical device. Talk to a doctor about any health decision.
