How to Manage a London Property from Japan

Owning a London property while living in Japan can feel a long way from straightforward. The time difference, the language of UK tenancy law, the certificates that must be renewed on time and the simple question of who turns up when a boiler fails all loom larger from eight time zones away. The good news is that many landlords let London homes from overseas without difficulty, and with the right structure in place distance becomes a detail rather than a difficulty. This guide walks through what you need to have in order and how to keep it running calmly from Japan.

Start with the legal framework you are now letting under

The rules for letting in England changed significantly when the Renters' Rights Act 2025 came into force on 1 May 2026. Fixed-term assured shorthold tenancies have been replaced by periodic tenancies that roll month to month, and the old Section 21 'no-fault' eviction route has been abolished. Possession is now available only through specific Section 8 grounds, such as the landlord selling the property, a landlord or close family member moving in, serious rent arrears or anti-social behaviour. If you are used to the old system, it is worth reading our overview of what the Renters' Rights Act 2025 means for London landlords before your next tenancy decision.

Rent increases are also more structured. You may raise the rent once a year, using a Section 13 notice that gives at least two months' written notice, and the tenant can challenge the figure at the First-tier Tribunal. The Tribunal cannot set a rent higher than the one you proposed, so a measured, evidence-based proposal is the sensible approach. Managing all of this from Japan simply means having someone on the ground who issues the correct notices at the correct times.

Get your compliance certificates in order and keep them current

Compliance is where remote landlords most often slip, because a certificate that lapses in London does not announce itself in Tokyo. The core obligations are consistent and worth diarising carefully. You will need a valid Energy Performance Certificate to market and let the property, with a minimum rating of E and a certificate that lasts ten years. Gas appliances require an annual Gas Safety Record from a Gas Safe registered engineer, and the electrical installation needs an Electrical Installation Condition Report at least every five years.

On top of that, every storey must have a smoke alarm and any room with a fixed combustion appliance must have a carbon monoxide alarm. Two newer obligations are arriving for the private rented sector as well: the Decent Homes Standard and Awaab's Law-style timescales for dealing with serious hazards. The practical answer for an overseas landlord is to hold all renewal dates in one place and have an agent or trusted contact book engineers well ahead of expiry, so nothing ever falls through.

Register, join redress and protect the deposit correctly

Landlords must now join a government-approved redress or ombudsman scheme and register on the new Private Rented Sector (PRS) Database. These are not optional housekeeping items; they are conditions of letting lawfully. If you use a letting agent who holds your rent, that agent must have Client Money Protection and belong to a redress scheme such as The Property Ombudsman, which is a reasonable question to ask before you appoint anyone.

Deposits carry their own rules. The deposit is capped at five weeks' rent where the annual rent is under £50,000, or six weeks' rent where it is £50,000 or more, and it must be protected in a government-approved scheme within 30 days, with the prescribed information given to the tenant. Remember too that under the Tenant Fees Act 2019 you cannot charge tenants for things like referencing or admin, and a holding deposit is capped at one week's rent. Some legal points are easier to get right with help, and our guide to letting a London property from overseas covers the setup steps in more detail.

Understand your tax position as a non-resident landlord

Tax is the area where being based in Japan changes things directly. If you are usually resident outside the UK for six months or more, you are treated as a non-resident landlord. In that case your agent, or the tenant where there is no agent, must deduct basic-rate tax from the rent unless HMRC has approved you to receive rent gross. Approval is applied for using form NRL1, and even when granted you remain liable for UK tax through Self Assessment. This is general information rather than tax advice, and given the interaction between UK and Japanese tax it is wise to consult a qualified accountant who understands both. We explain the mechanics further in our piece on non-resident landlord tax in the UK.

Decide how the day-to-day will actually be handled

The question that matters most from Japan is simple: who acts when something happens? A tenant reporting a leak at 9pm London time needs a response that does not depend on you being awake. This is why most overseas owners use a full management service rather than a let-only arrangement. A managing agent collects the rent, handles repairs, serves the correct notices, keeps compliance current and is the named point of contact for the tenant, which removes much of the friction of distance.

If you would like to understand exactly where the lines fall between finding a tenant and running the tenancy, our explainer on what a letting agent does in London sets it out plainly. When you are choosing who to trust with the property, it is reasonable to weigh experience, communication and how well they will keep you informed across the time difference; our notes on how to choose a letting agent in London may help you ask the right questions.

Build communication that works across the time difference

Distance is mostly a communication problem, and it is a solvable one. Agree at the outset how you want to be kept updated, how repairs are authorised up to a set value without waking you, and how statements and certificates are shared. A good arrangement means you hear about the property when there is a decision to make and otherwise simply receive your rent and a clear monthly statement. Bilingual support can be reassuring here, particularly when tenancy paperwork and legal notices are involved, though the underlying obligations are the same for every landlord regardless of nationality.

Treat anti-discrimination and fair letting as part of good management

The current rules also set clear standards for how tenants are treated. Discrimination against families with children or against tenants receiving benefits is prohibited, and rental bidding wars are banned, which means you must advertise an asking rent and cannot invite or accept offers above it. Tenants also have a stronger position on pets: a tenant may ask to keep one and you must not unreasonably refuse, though you may require pet insurance. Letting fairly is not only a legal duty under the Equality Act 2010 and the new rules; from Japan it is also the simplest way to run a stable, low-conflict tenancy.

If you are weighing up whether to manage remotely yourself or hand the whole thing over, the honest answer for most landlords in Japan is that a reliable agent can save considerable time and reduce the risk of something being missed. We work with many landlords who are based abroad, including a number of Japanese owners alongside clients of every background, and we are always happy to talk through your particular property and what good management would look like for it.
