Emergency availability
Everything Your Plumbing Needs
Six specialist service areas, one reliable team. Whether it’s a 3 AM emergency burst pipe, a water heater installation, or planned drain maintenance, we have the tools, the certification, and the experience. Every service is backed by our 12-month guarantee.
Emergency Plumber
Burst pipes at midnight? Blocked bathroom at 3 AM? We’re available 24/7 with round-the-clock rapid response — typically on-site within 60 minutes across Tokyo. Our technicians can stabilize most emergencies over the phone while we drive.
Water Heater Installation
Full supply and safe installation of gas, electric, and heat-pump water heaters from Japan’s established brands. We handle disconnection, old unit disposal, all pipework connections, venting, and commissioning tests. Your new heater carries a 5-year manufacturer warranty.
Pipe Repair & Relining
From pinhole leaks in visible pipes to full-system trenchless relining behind walls, we restore pipe integrity with minimal disruption to your home or business. We use advanced diagnostics to find the problem, then choose the repair method that best protects your property.
Drain Cleaning
Slow drains? Foul odours? We deploy CCTV cameras to inspect the blockage, then use high-pressure hydro-jetting to clear it thoroughly. Includes a written inspection report. Same-day emergency service available for severe blockages affecting multiple fixtures.
Bathroom & Kitchen Fit-Out
Complete plumbing for new builds and renovations — rough-in planning, fixture supply from quality manufacturers, final connections, commissioning, and handover documentation. We work to Japanese building codes and integrate seamlessly with your builders and architects.
What Sets Us Apart
Built for Speed, Precision, and Reliability
Every Brook Blend Field technician undergoes 200+ hours of annual training and is equipped with advanced diagnostic technology — acoustic sensors, thermal imaging, CCTV cameras. We hold current Japanese plumbing certification and full liability coverage. We work around your schedule — not ours — and we show up on time, every time. Your satisfaction is not a hope; it’s our 12-month promise.
01
Certified Japanese Plumbing Professionals
All team members hold current national certification under Japan’s Plumbing Works Business Act and carry full liability coverage. We undergo mandatory recertification every two years and invest heavily in continuing education. Our lead technicians hold advanced qualifications in gas fitting, water heating systems, and trenchless technology — ensuring your job is in expert hands regardless of complexity.
02
Same-Day & Emergency Response
Our dispatch centre operates 24 hours, 365 days a year, including all public holidays. For emergencies, our target arrival time is under 60 minutes anywhere in Greater Tokyo. We maintain on-call rosters at our three response hubs — Shinjuku, Shibuya, and Koto — so someone is always minutes away. Out-of-hours surcharges are disclosed upfront and apply only to 19:00–08:00 calls outside weekday business hours.
03
Transparent, Itemised Quotes
You receive a full written quote before any work begins, itemising labour, parts, disposal, and any incidentals. No hidden fees, no surprise add-ons — your final invoice matches the approved quote line-for-line. If we discover additional issues during the job, we contact you immediately with options and pricing before proceeding. You remain in complete control.
04
12-Month Workmanship Guarantee
Every repair and installation is covered for a full year from completion. If an issue arises from our workmanship — not from wear, misuse, or pre-existing conditions — we fix it at no additional cost. Your warranty certificate is issued on the spot, and you can file a claim anytime within 12 months. We back our work with confidence because we know it’s done right.
Four Steps to a Fixed Plumbing System
Getting your plumbing sorted has never been easier. We’ve refined our process to minimize disruption and confusion. Here is exactly what to expect from the moment you call Brook Blend Field to the moment we leave your property cleaner and better than we found it.
Call or Book Online
Reach us on +81 3-3733-6977 any time of day or night, or submit a booking request through our contact form and we will call you back within 30 minutes. Tell us what’s wrong and when you’d like us to visit. For emergencies, we can often send someone the same hour.
Diagnosis & Quote
Your technician inspects the issue with professional diagnostic tools — acoustic sensors, thermal imaging, CCTV cameras — and provides a clear written quote itemising all labour, parts, and fees. No work starts until you approve it in writing. Nothing hidden.
Expert Repair or Installation
We complete the job cleanly and efficiently, using only quality-certified parts and following all Japanese building standards and safety codes. You’ll see what’s being done and can ask questions anytime. We protect your home and leave zero mess behind.
Review & Guarantee
We walk you through what was done, test everything for safety and performance, leave the workspace spotless, and hand over your 12-month workmanship warranty certificate. You have our contact details and a direct line if you ever need us.
Choose the Right Package for Your Needs
Fixed prices. No hidden costs. All packages include a full inspection report and our 12-month guarantee.
Emergency Call-Out
24/7 rapid response for burst pipes, major leaks, or blocked drains that need immediate attention. Includes up to 1 hour of diagnostic labour, emergency shutdown procedures, and supply of basic parts (connectors, washers, stopcock repairs). We bring mobile diagnostic tools and can often resolve the issue same-day. If a complex repair is needed, we provide a transparent quote before proceeding.
Water Heater Installation
Full supply and installation of a new gas, electric, or heat-pump water heater from trusted Japanese brands (Rinnai, Noritz, Toto). Includes safe disconnection and disposal of your old unit, all hot-water pipework connections, safety valve installation, and full commissioning test. We handle venting, permits, and building-standard compliance. The price includes the heater unit, labour, and 5 years of manufacturer support.
Pipe Repair Service
Diagnosis and repair of leaking, cracked, or corroded pipes caused by age, freezing, scale build-up, or mechanical damage. This package covers up to 2 metres of exposed copper, plastic, or steel pipework with traditional repair methods. If your pipes run behind walls or under slabs, we can offer trenchless relining — a no-dig solution that avoids structural damage. Acoustic leak detection is included to pinpoint exact problem areas before we start work.
Leak Detection Package
Comprehensive acoustic and thermal imaging survey of your complete plumbing system — detecting leaks behind walls, under slabs, or in concealed pipework before they cause major damage. You receive a professional written report with precise leak locations, severity assessment, and recommended repair options. This service often saves thousands of yen by catching small leaks early. Perfect for homes with mystery moisture issues or mysteriously high water bills.
Drain Cleaning Service
High-pressure hydro-jetting of kitchen, bathroom, or floor drains — clearing soap scum, hair, grease build-up, and mineral scale that slow drainage or cause odours. We deploy a CCTV inspection camera into the drain first to identify blockages and assess pipe condition, then clean with precisely calibrated pressure. A written CCTV report is included so you know the state of your drains. Same-day service available for urgent blocks.
Annual Maintenance Plan
Two comprehensive full-system inspections per year (spring and autumn recommended), priority emergency booking, 15% discount on all repair and service calls, and a dedicated account manager familiar with your property’s history. Ideal for landlords, commercial property managers, or anyone who values peace of mind. We catch small issues before they become expensive crises — paying for itself many times over.

Case Study
Full Bathroom Replumb in Shinjuku High-Rise
A 24-storey residential tower in Nishi-Shinjuku was experiencing chronic low water pressure, recurring pipe corrosion, and rising maintenance costs across the building’s original 1998 copper network. The property manager had two options: monthly emergency repairs or a complete replumb. They chose Brook Blend Field.
We surveyed all 18 occupied floors, created a phased schedule that minimized resident disruption, and replaced the entire original copper system with modern cross-linked polyethylene piping. Acoustic testing confirmed zero noise impact on adjacent units. The new system carries a 12-year warranty. The building has had zero plumbing incidents since completion.
“Brook Blend Field’s team completed a full cross-linked polyethylene replumb across 18 floors in just 11 days with zero resident complaints about noise, access, or cleanliness. Their professionalism and respect for the building gave us confidence immediately.”

FAQ
Common Questions, Answered
We get a lot of the same questions from new customers — about our response times, pricing, service areas, and how we work. Below are honest, detailed answers. Still have questions? Call our 24/7 line on +81 3-3733-6977 and speak to a real person.
Our target response time for emergencies across Tokyo is under 60 minutes. For Shinjuku and surrounding wards we typically arrive in 30–45 minutes. We maintain on-call technicians 24 hours a day, 365 days a year — there is always someone ready to respond. During high-demand periods (typhoon season, winter freezes) response may take longer, but we communicate transparently and provide interim advice over the phone to minimize further damage while you wait.
Yes. Our emergency line and on-call crews operate every day of the year including all Japanese public holidays. We offer the same rapid response on weekends and holidays as we do on weekdays. A small after-hours surcharge applies only to non-emergency calls outside 08:00–19:00 on weekdays; this surcharge is always disclosed before any work begins and is clearly itemized on your quote.
Most of our standard services—emergency call-outs, water heater installations, drain cleaning, pipe repairs—are priced as fixed packages, as listed on this website. For bespoke or complex projects (multi-unit buildings, commercial fit-outs, trenchless relining), we provide a detailed itemised quote before any work begins, breaking down labour, materials, and timelines. You will never be billed more than the approved quote without your express consent.
We serve all 23 special wards of Tokyo (Shinjuku, Shibuya, Minato, Taito, Chiyoda, etc.) and extending into greater metropolitan Tokyo including Kanagawa, Saitama, and Chiba prefectures. Our headquarters is in Nishi-Shinjuku with additional response hubs in Shibuya and Koto. For bookings outside our primary zone, we can provide estimates — contact us for details.
Do you supply parts and materials, or should I buy them?
We supply all standard parts and materials from our vetted, quality-certified supplier network, and the cost is reflected in your quote. If you have already purchased specific fixtures or prefer a particular brand, we are happy to install those too — just let us know when booking and we will adjust the quote accordingly. We never mark up customer-supplied materials.
Still Have a Question?
Our team is available 24 / 7 to answer any queries before you commit to a booking.
