Tokyo Tap Water vs. Bottled Water: The Japanese View
| Factor | Tap Water (水道水 Suidōsui) | Bottled Water (ミネラルウォーター) |
|---|---|---|
| Cost | FREE | ¥100-200 per bottle |
| Quality | Tested 200+ times daily | Less frequent testing |
| Taste | Clean (ozone-treated) | Varies by brand |
| Environmental | ♻️ Zero waste | 🚫 Plastic pollution |
| Cultural | 🇯🇵 “Japanese quality!” | 😬 “Wasteful” (mottainai!) |
Japanese Culture Note: “Mottainai” (もったいない) = wasteful. Tokyo tap water is world-class - buying bottled for pets goes against Japanese values of efficiency and quality.
For Dogs: Carry your own bottle and refill = very Japanese approach!

Myths About Tokyo Water (Debunked!)
Myth 1: “You need bottled water in Japan because of Fukushima”
❌ COMPLETELY FALSE: Tokyo water comes from rivers/aquifers FAR from Fukushima. Water is tested for radiation DAILY (has been for 10+ years). Results are public and show ZERO contamination. This is fearmongering!
Myth 2: “Japanese people only drink bottled water”
❌ FALSE: Most Japanese drink tap water at home! Bottled water is for convenience (on-the-go), not safety. Tokyo tap water is a source of national pride.
Myth 3: “Tap water is different in old Tokyo buildings”
⚠️ PARTIALLY TRUE: Very old buildings (pre-1970) may have old pipes. Modern apartments and hotels are fine. If staying in old ryokan, ask “suidō wa daijōbu desu ka?” (Is tap water okay?)
Myth 4: “Dogs shouldn’t drink ozone-treated water”
❌ FALSE: Ozone breaks down to oxygen (O3 → O2). It’s safer than chlorine! Japanese vets recommend tap water for all pets.
FAQ: Tokyo Dog Tap Water Questions
Do Tokyo dogs actually drink tap water?
もちろん! (Of course!) Japanese pet culture emphasizes quality - tap water is considered best for dogs. Visit any dog run and you’ll see owners refilling bowls from fountains. Buying bottled water for pets is seen as “mottainai” (wasteful) when tap water is world-class!
Can I ask konbini staff for water for my dog?
Yes, politely! Japanese service culture is amazing. Say: “Sumimasen, inu no mizu onegai shimasu” (Excuse me, water for dog please). Most staff will help, though some stores may not allow dogs inside. Better: ask them to fill your collapsible bowl outside!
Is Tokyo summer too dangerous for dogs?
Tokyo summer (July-Aug) is extremely hot (30-35°C + humidity). Many vets recommend avoiding midday walks entirely. Safe approach: Walk only 5-7am or after 8pm, carry 1.5L water minimum, use cooling products, watch for heat stroke signs. Consider visiting in spring (March-May) or fall (Sept-Nov) instead!
Are Japanese dog parks strict about rules?
YES - very organized! Most dog runs require: (1) Registration (free, bring vaccine records), (2) Dogs must be leashed until inside fenced area, (3) Clean up waste immediately (bags provided), (4) Owners responsible for any incidents. Rules are clearly posted in Japanese/English. Follow etiquette carefully - Japanese pet culture values respect!
Final Verdict: Tokyo Tap Water for Dogs
