Spring Pet Care Guide: Rabies Vaccination & Flea/Tick Prevention for Dogs in Japan

Is Your Dog Up to Date on Spring Preventive Care?

Every April, many dog owners in Japan suddenly realize they haven't completed two critical tasks: the mandatory annual rabies vaccination and starting flea and tick prevention. If you're in that situation right now, you're not alone—and the good news is there's still time to get everything sorted.

Under Japan's Rabies Prevention Act, all dogs over 91 days old must be vaccinated annually and registered with the local municipality. Failure to comply can result in fines of up to ¥200,000. Meanwhile, fleas and ticks become active once temperatures rise above 13°C (55°F)—which means most parts of Japan are already in tick season by April.

This guide covers everything you need to act on right now: vaccination schedules, costs, flea and tick prevention options, and the post-care checklist to keep your dog safe all spring.

Rabies Vaccination in Japan: What You Need to Know

Legal Requirement and Timing

The official vaccination period is April 1 to June 30 each year. There are two ways to get your dog vaccinated:

After vaccination, your dog must wear both the registration tag (鑑札) and the vaccination tag (注射済票) on their collar at all times. This is a legal requirement.

New Dog Registration Steps

If you've recently adopted a puppy or dog who hasn't been registered yet:

1. Visit your local municipal office (or a participating vet clinic) to register your dog — registration fee is approximately ¥3,000.
2. Receive your dog's registration tag.
3. Get the rabies vaccination.
4. Receive the vaccination tag and attach both tags to the collar.

Common Mistake: Skipping the Vaccination Without Consulting a Vet

If your dog seems a little off, it's tempting to delay. However, self-deciding to skip the vaccination without veterinary guidance is a mistake. If your dog has a diagnosed medical condition or confirmed fever, a vet can issue a written exemption to submit to the municipality. Never skip without documentation.

Flea and Tick Prevention: Why April Is the Right Time to Start

The Risk Is Real

Fleas and ticks are more than just an itchy nuisance. The health risks include:

• Fleas: Tapeworm (Dipylidium caninum) transmission, flea allergy dermatitis
• Ticks: Babesiosis (destroys red blood cells), Severe Fever with Thrombocytopenia Syndrome (SFTS) — a zoonotic disease with a case fatality rate of approximately 6–30% (National Institute of Infectious Diseases, Japan)

SFTS can be transmitted from infected pets to humans, making prevention a public health matter, not just a pet health issue.

Comparing Prevention Options

Important: All effective flea and tick preventatives in Japan are prescription-only medications. Do not purchase products from unauthorized online retailers or import from overseas—unapproved products carry serious safety risks. Always obtain these from a licensed veterinarian.

Critical Warning: Never Use Dog Products on Cats

Many dog flea/tick products contain pyrethroids, which are highly toxic to cats and can be fatal. If you have both dogs and cats, always verify the species on the label before use.

Post-Care Checklist: What to Watch After Vaccination and Treatment

After Rabies Vaccination (First 24–72 Hours)

• Stay near the clinic for at least 30 minutes post-injection
• Watch for facial swelling, vomiting, or sudden lethargy (signs of anaphylaxis — seek emergency care immediately)
• Avoid strenuous exercise and bathing on the day of vaccination
• Check the injection site for unusual swelling over the next 2–3 days
• Confirm normal appetite and energy the following day

After Flea/Tick Medication

• Avoid bathing or swimming for 48 hours after topical application
• Prevent other pets from licking the application site until dry
• Watch for vomiting, diarrhea, tremors, or neurological signs — contact your vet immediately if these occur
• Note the date and schedule the next dose

When to Call Your Veterinarian

• Your dog has a pre-existing condition (heart disease, epilepsy, kidney disease)
• Your dog is pregnant or nursing
• Any unusual symptoms appear after vaccination or medication
• You're unsure which flea/tick product is appropriate for your dog's size or health status

Manage Spring Preventive Care with PETTAS

Keeping track of annual vaccinations and monthly medications is easy to let slip. The PETTAS Vaccine Schedule Manager lets you log your dog's rabies vaccination date and sends a reminder when next year's vaccination window approaches — so you're never scrambling in April again.

For monthly flea and tick prevention, the Medication Reminder feature sends you a push notification on the day treatment is due, preventing missed doses. If you share pet care responsibilities with a partner or family member, the Family Sharing feature lets everyone see who administered the last treatment in real time, eliminating the risk of accidental double-dosing.

All vaccination records, medication logs, and health notes are stored in the Health Timeline, which makes vet visits faster and more informative.

3. Log today's actions in an app or calendar: Whether you use PETTAS or another tool, record the vaccination and medication dates immediately — your future self will thank you when April rolls around next year.
