The ultimate guide to buying London property for Japanese investors

London stands as one of the most trusted residential property markets in the global market. For discerning Japanese investors, this city offers rare benefits such as long-term legal certainty, strong rental demand, transparent ownership structures and a global tenant base. These factors, in return boost stable rental income across market cycles.

We have developed this guide specially for Japanese buyers interested in buying London property. Whether you are a high-net-worth individual diversifying your international portfolio, a parent purchasing an apartment for your child studying in the UK or a corporate buyer housing staff, this practical breakdown should help.

Why does London appeal to Japanese investors?

London’s appeal is rooted in fundamentals rather than speculation. Property ownership rights in the UK are clearly defined, contracts are secure and enforceable and overseas buyers face no restrictions when purchasing a property here. Rental demand in the capital is consistent around the year and driven by global employers, universities, financial institutions and the inflow of international professionals.

Well-located, spacious apartments, especially one and two-bedrooms in well-established neighbourhoods, continue to attract reliable tenants. For Japanese investors with a long-term investment mindset, London property is often viewed as a capital-preserving asset that also yields steady income.

Property ownership in London

Most apartments in London are sold on a leasehold basis. This structure has been well established in the UK for decades and gives buyers legal rights to occupy the property for a fixed term (between 125 and 999 years) in most modern developments. Leaseholders contribute to the maintenance of the building through service charges, which cover insurance, repairs, cleaning and shared facilities. Some older leases also require ground rent, a fixed annual payment to the freeholder.

Houses sold as freehold imply that the buyer owns the building and the land outright. However, apartments still stand as the preferred choice for most international property buyers due to factors like location, rental demand and ease of management.

Guide to buying property in London from Japan

Plan your finances: Decide how you'll fund the purchase and the budget you’d like to allocate to it. Many Japanese investors buy a property in London using overseas assets or savings. Buyers can also explore UK mortgage options.

Mortgage: UK mortgages are available to overseas investors, including Japanese residents, subject to lender approval. Income, asset position and credit profile are factors that are typically reviewed when applying for a mortgage in London.

Documentation: Typical documents include a valid passport, proof of address, recent bank statements showing available funds and supporting evidence explaining how the funds were collected.

Define property search: London comprises 32 boroughs. A focused approach is ideal for better outcomes. As a buyer, ensure you define the purpose of the purchase, preferred location(s), property size and whether the property is intended for investment, personal use or a combination of both.

Viewing and shortlisting: Viewings can be conducted either in person or remotely. With Benham & Reeves, most overseas buyers, including Japanese investors, can complete the property purchase without travelling to the UK.

Offer and reservation: Once a suitable property is identified, an offer is submitted to the seller. If the offer is made for a new build property, a reservation fee is usually paid to secure the unit.

A UK solicitor: All property transactions in the UK are conducted through solicitors. He reviews contracts, carries out legal checks and raises enquiries all on the buyers’ behalf.

Exchange of contracts: This step makes the transaction legally binding. A deposit, approximately 10% of the purchase price, is paid at this point.

Completion and ownership: At this stage, the buyer needs to transfer the remaining balance to the seller’s solicitor. He then becomes the legal owner of the London property.

Purchase costs and stamp duty: Stamp Duty Land Tax (SDLT) is applicable on all UK property purchases and includes a surcharge for non-UK residents.

Rental income and types of tax

Rental income from UK property is taxable in the UK. However, allowable costs such as letting fees, management charges, service charges, maintenance and insurance can be deducted before tax is calculated. Japan and the UK have a double taxation agreement, which means that tax paid in the UK can generally be offset against Japanese tax liabilities under the foreign tax credit system.

Capital gains tax is a type of tax that is applicable when a UK property is sold. This tax is calculated on the profit after deducting allowable purchase costs, improvement expenses and selling fees.
