For a Japanese investor considering property investment in London, the first thing worth checking is how consistent the demand is and what is actually holding it up. That answer decides how reliable the rental income will be, whether the property holds its value and how London is different from other markets.
The core problem: London does not build enough homes
London's property market has one defining trait: supply has consistently failed to keep pace with demand for decades. The government's target, first set under the 2019 manifesto and reaffirmed as part of the current pledge to deliver 1.5 million homes this parliament, is for England to build 300,000 new homes every year.
Delivery has fallen well short. The Ministry of Housing, Communities and Local Government recorded 208,600 net additional dwellings in England for 2024-25, a 6% decrease on the previous year, the lowest for a financial year since 2015-16. England has not come close to the 300,000 target in recent years on record.
In London specifically, the gap is acute. When supply sits below demand for this long, values and rents are underpinned over the long run. Individual years move differently. 2026 has been a softer year for London values, but the underlying pressure has not eased.
Continued population growth
London's population grew by more than half a million in the decade to 2023, taking it to around nine million. The city keeps drawing professionals, students and families from across the UK and overseas.
For an international investor, this is what turns a supply shortage into a rental income opportunity. Add a growing population to an undersupplied market and tenants start to outnumber properties, which is what keeps voids short and rents stable.
London tenant profile
Understanding who rents in London matters more than generic "demand is high" statements.
The London rental market is supported by several distinct tenant groups, each with different income profiles for landlords.
Young professionals
London remains Europe's largest financial centre and one of the world's leading tech hubs.
Young professionals, typically aged 25 to 40, working in finance, tech, media and legal services, form the single largest renter cohort.
Shoreditch and Hackney, Clapham and Brixton and Canary Wharf and Greenwich are among the areas with the strongest demand from professional renters in early 2026. These are tenants with stable incomes who tend to look after what they rent.
University students and postgraduates
London is home to UCL, King's College London, Imperial College, LSE and dozens of other universities.
Student enrolment across London's institutions runs into the hundreds of thousands. London Higher, the representative body for close to 50 universities and colleges in the capital, has put the figure at over half a million students, a number it reports annually alongside HESA's national data.
Student tenants, particularly postgraduates and international students, consistently generate rental demand near university campuses.
Many parents of foreign students choose to buy rather than pay rent, particularly for stays of three or more years.
Corporate and expat tenants
London's concentration of multinational company headquarters, embassies and international organisations generates demand from corporate tenants for fully furnished, professionally managed lettings.
These tenants typically pay a premium for well-presented properties and professional management.
London as a global education hub
QS ranked London in the top three in its 2026 Best Student Cities index, after holding the number one spot for six consecutive years running. Few cities in the world combine this level of academic reputation with the sheer scale of demand it generates. The concentration of globally ranked universities in London is a consistent demand driver, independent of economic cycles.
LSE, UCL, King's College and Imperial College all have significant Japanese and broader Asian student populations. Areas within easy reach of these campuses, such as Bloomsbury, South Kensington, Hammersmith and Canary Wharf, generate consistent rental demand thanks to this demographic.
When a Japanese family sends a child to study in London for three years, the choice between paying rent and buying a property is often made in favour of buying. The property is used during the study period and let afterwards. This turns into a practical, cost-effective approach that also builds a GBP-denominated asset.

London as a global financial centre
The depth of London's financial services sector is a consistent anchor for property demand. The City and Canary Wharf together represent one of the world's largest concentrations of financial activity.
Legal services, professional services and the tech cluster around Shoreditch and Old Street add further employment density, directly generating demand for housing. Rental demand tends to track the sector. It rises when these industries expand and when they contract (as they did in 2020), the structural undersupply cushions the fall. That status does not come and go with the cycle. It is built into what the city is.
Which areas have the strongest rental demand?
Rental demand is not uniform across London. In early 2026, areas with strong rental yields include Wembley (6%) and Woolwich (5–6%). These London neighbourhoods have benefited from extensive regeneration, with improved transport links, lower entry prices, and evergreen demand from professional tenants. Neighbourhoods such as Stratford and Abbey Wood, that are located along the Elizabeth Line are also seeing rising rental demand. Here’s a simple guide to rental demand and yields in London. Prime central London (Kensington, Mayfair) offers lower yields of 2.5–3.5% but attracts corporate and high-net-worth tenants. For income-focused investors from Japan, the outer London areas with strong rental demand and reliable yields make more sense.
Well-located one-bedroom and studio flats consistently outperform larger units on a yield basis. To understand the best property as per your requirements, speak with Benham and Reeves Japan Desk for personalised market insights.
The short-term picture vs. the long-term case
Rents in London are still climbing even as capital values have cooled. The structural undersupply has not gone anywhere. For investors who plan in decades, which many Japanese family offices and long-term holders do, the softer market right now reads as an entry point.
