# Pet Microchip Mandates and Individual Identification Basics | Complete Guide to Registration Procedures, Costs, and Applicable Animals
When you first start keeping a pet, have you ever wondered, "What exactly should I do about microchipping?" Since June 2022, when the revised Animal Protection Law came into effect, microchip implantation has been mandated for dog and cat breeders and sellers. However, there are many lesser-known aspects, such as which animals are covered, how to handle pets you already own, and the benefits of implanting microchips in reptiles, birds, and other non-canine/feline species.
This article systematically explains everything you need to know about pet individual identification—from how microchips work to registration procedures, costs, and their relationship to direct breeder sales.

A microchip is a cylindrical electronic identification device approximately 2mm in diameter and 12mm in length. Inside, an IC chip and antenna are sealed. When read with a dedicated reader, it displays a unique 15-digit number.
Implantation uses a syringe-like injector to insert the microchip subcutaneously. For dogs and cats, the standard implantation site is the back of the neck (subcutaneous space between the shoulder blades).

The 2019 Animal Protection Law revision established the following rules, effective June 1, 2022.
| Target | Obligation | |--------|-----------| | Dog and cat sellers (breeders, pet shops) | Microchip implantation mandatory before sale | | General pet owners (new acquisition) | Registration transfer mandatory after purchase/receipt | | General pet owners (existing pets) | Microchip implantation is a best-effort obligation |

Only veterinarians can implant microchips. The procedure can typically be done during regular clinic hours and takes just a few minutes.
After implantation, register the chip with Japan's environmental ministry–designated registration organization (the Japan Veterinary Medical Association's "Microchip Information Registration for Dogs and Cats" website) online.
Required Registration Information - Microchip identification number - Owner's name, address, and telephone number - Animal's species, breed, coat color, sex, and date of birth - Information about the veterinary clinic that performed the implantation
Once registration is complete, a certificate (PDF) is issued. Keep this certificate carefully, as you'll need it in the following situations:
---
| Item | Cost Range | |------|-----------| | Microchip implantation fee (animal hospital) | ¥3,000–¥10,000 (varies by facility) | | Registration fee (online) | ¥300 | | Registration fee (paper application) | ¥1,000 | | Registration transfer fee | ¥300 (online) |
Implantation costs vary by veterinary hospital, but typically around ¥5,000. If performed simultaneously with neutering/spaying or health checkups, you can reduce the number of clinic visits.

Under current law, microchip implantation is mandated only for dogs and cats. However, cases of microchipping reptiles, birds, and small animals are increasing.
Reptiles - Species listed in CITES (Convention on International Trade in Endangered Species) Appendix I may require microchip-based individual identification for international trade - High-value individuals like ball pythons, chameleons, and monitor lizards benefit from microchip implantation as theft prevention - Reptiles are difficult to identify by appearance alone, making microchips useful for bloodline management
Birds - Large parrots and psittacids can live 50+ years, making them ideal for long-term individual management - Leg bands can fall off, so microchips serve as a reliable backup identification method - Useful for documenting ownership of high-value rare species
Small Animals - Ferrets, chinchillas, rabbits, and other small animals can be implanted, though extremely tiny individuals may not be suitable - Consult with a veterinarian to determine whether implantation is appropriate
Plants are not implanted with microchips, but other methods manage high-value specimens like rare agaves and caudexes.

When purchasing livestock directly from a breeder, confirm the following microchip-related points for a smooth transaction.
Since June 2022, dog and cat breeders have been legally required to implant microchips before sale. The chip should already be in place at the time of purchase.
What Buyers Should Do 1. Obtain the microchip identification number and implantation certificate 2. Submit a registration transfer with the designated registration authority (within 30 days) 3. Keep the registration completion certificate
While not legally required, for high-value or rare species, we recommend confirming the following with the breeder before purchase:
On Br-choku, you can message breeders directly before purchase, allowing you to verify detailed information about the animal, including microchip status.

This is rare, but when it occurs, the chip typically remains near the implantation site. Within a few days, surrounding tissue stabilizes the chip, making significant migration extremely uncommon.
Standard microchips don't interfere with MRI or X-ray examinations. However, minor imaging artifacts (noise) may appear around the chip area during MRI. Inform your veterinarian of the chip's presence before any examination.
No. Microchips work only when a dedicated reader recognizes the number—they don't transmit location data. If real-time tracking is necessary, use a GPS-enabled collar or separate tracker device.
While legally a best-effort obligation, implantation is strongly recommended. If your pet is lost or escapes and is found, a microchip ensures reunion with you even if the collar has fallen off. The 2011 Tōhoku earthquake and 2016 Kumamoto earthquake both saw numerous cases where microchips reunited pets with their owners.

The microchip is a foundational system supporting your pet's safety and your peace of mind.
On Br-choku, you can purchase livestock directly from certified breeders and verify microchip status and individual history before purchase. If you're seeking a safe, reliable way to welcome a new animal, try Br-choku.
