Sockets
Replacing a loose, burnt or cracked socket, adding an outlet, converting to an earthed or USB type.
A socket that no longer holds the plug, a switch that has stopped working, a ceiling light to replace, a breaker that keeps tripping, an air conditioner to install. Small jobs, done quickly and legally, by a licensed electrician who explains the work in English or French — and deals with your 管理会社 in Japanese.
Most of these take under an hour. Send a photo and you will get a price before anyone comes out.
Replacing a loose, burnt or cracked socket, adding an outlet, converting to an earthed or USB type.
Replacing a switch that no longer clicks or sparks, fitting a dimmer, a two-way switch or a motion sensor.
Removing and fitting ceiling lights, installing a ceiling rose, converting old fittings to LED.
Finding the actual cause rather than resetting it: overloaded circuit, faulty appliance, earth leakage, ageing board.
A separate circuit for an air conditioner, an IH hob, a washer or a dryer, so it stops sharing with everything else.
Earthed outlets for washing machine, dishwasher or microwave, and safety checks in kitchens and bathrooms.
Replacing a dead intercom handset or doorbell, fitting a unit with a camera and a screen.
Washing machine, dishwasher, IH hob or dryer — connected properly, with the dedicated circuit and earthed outlet they require.
Installation, removal, relocation and cleaning of residential air-conditioning units.
In Japan, work on fixed wiring — sockets, switches, ceiling roses, distribution boards — is reserved by law to a licensed electrician (電気工事士法). It is not a formality: it is what makes the work legal, insurable, and acceptable to a landlord or building management company.
Doing it yourself, or letting an unlicensed handyman do it, exposes you to three concrete risks:
We hold the Japanese Class-2 electrician licence (第二種電気工事士), which covers residential installations up to 600V. The work is done to standard and you get a written invoice you can show to whoever asks.
Describe the problem and attach a photo of the socket, switch or board. That is usually enough to identify the job.
You receive a price and a time slot before anything is booked. No call-out that turns into an open-ended bill.
The work is carried out and you get a written invoice — useful for a landlord, an insurer or an employer.
Getting a small repair done in Japan is rarely a technical problem. It is a phone call in Japanese to a company that only works in Japanese, about a flat you do not own, in a building with its own rules.
Based in Tokyo, working across the 23 wards. Most jobs are booked for the next day or two; a socket that sparks or a flat with no power is treated as urgent.
By appointment, we also cover the wider Kanto region — Chiba, Kanagawa (Yokohama, Kawasaki…), Saitama and beyond. For a half-day of work it is often still worth the trip, and we will tell you honestly if it is not.
Yes. We work in Japanese, English and French every day. You will get the explanation before the work, the price before the visit, and the invoice afterwards — in your language, not in translated fragments.
It depends on the job, but you will never find out on the day. Send a photo of the socket, the switch or the distribution board with a line about the problem, and you get a price before anyone travels. The estimate costs nothing.
Usual hours are 8:00–19:00 on weekdays. Weekends are possible by arrangement. If there is a burning smell, a socket that sparks or a flat with no power, say so in the first line and it is treated as urgent.
Yes. Two things to check first: whether the room has a dedicated circuit (専用回路) at the right voltage, and whether there is already a sleeve through the wall. If either is missing it becomes electrical work, which needs a licence — and you will know the cost before, not on the day.
Not always. Japanese homes are supplied under a contracted amperage (契約アンペア), often 30 A in an older flat, and a microwave plus a kettle plus a hairdryer will exceed it — that is a contract question for the power company, not a repair. But a breaker that trips with almost nothing running is a fault, and should be looked at.
For anything that drills, fixes to the façade or changes the fixed installation, yes — from the owner or the 管理会社. We can ask them in Japanese and get it in writing, which is far easier than explaining it at move-out when 原状回復 is being calculated.
Yes, describing the work and naming the licence holder who did it. That is exactly the document an insurer, a landlord or an employer will ask you for later, and it costs nothing to issue.
For flat-pack furniture or a leaking tap, a handyman is fine. But anything connected to the wiring in the walls — sockets, switches, the distribution board, an air conditioner — is reserved by the Electricians Act to licence holders. Unlicensed work is what an insurer looks for after a fire.
A photo of what is wrong, the address and floor, whether it is a mansion or a house, and if you know it, your contracted amperage — it is written on the main breaker. That is usually enough to arrive with the right parts.
Bank transfer or cash, after the work, against the invoice. No deposit for a normal job.
Site inspection, installation, maintenance or technical representation — describe your need and you will get a reply the same day if it reaches us between 08:00 and 19:00 JST on weekdays. Weekends by arrangement.
The form does not take attachments — send photos to contact@daksolutions.jp, mentioning your name.
No job is too small. Send a photo and you will get a price the same day.
