Demand for renovated properties in Tokyo is rising rapidly. Renovation, which makes it possible to obtain interiors comparable to new construction at a more accessible price than a newly built property, is attracting broad interest from single residents to families. This article explains the factors behind the increase in renovation projects in Tokyo and the benefits they offer.

Why are renovated properties increasing so rapidly in Tokyo?

The rapid increase in renovations in Tokyo is closely tied to changes in the social structure. Even as Japan faces a declining birthrate and an aging population, Tokyo’s population continues to trend upward, especially among single-person households. As a result, demand is growing to renovate traditional family-oriented properties into one-room units or share houses.

What are the benefits of changing a property's role through renovation?

The greatest advantage of renovation is that it allows a property's use to be changed flexibly in line with the times. By converting family-oriented properties for single occupants or using them as guesthouses or share houses, owners can recreate value in properties that had been underutilized.

Why is renovation chosen instead of new construction?

There are two main reasons renovation is chosen in Tokyo.

  • Regulatory and permitting hurdles: Rebuilding requires construction permits, while renovation is generally easier to approve because it is treated as remodeling. In particular, due to changes to the Building Standards Act, there are cases where even properties that can no longer be rebuilt can still be addressed
  • Differences in construction scale: New construction involves large-scale work starting from a cleared site, whereas renovation focuses mainly on the interior and can reuse the existing structural base, substantially reducing both cost and project duration

In Tokyo, the following renovation examples are increasing.

  • Conversion to share houses: This responds to demand from single residents and students who want to keep rent low. Cases that include shared kitchens and lounges are also increasing
  • Renovations matched to area characteristics: Shibuya and Roppongi cater to active younger residents, while Shinagawa and waterfront areas favor a more calm atmosphere. Designs tailored to each neighborhood’s character are a clear trend

Frequently Asked Questions (FAQ)

Q. Are renovated properties cheaper than newly built ones?

In general, they can be acquired at roughly 60% to 80% of the price of a newly built property. However, costs vary significantly depending on the scope of work.

Q. Are there any disadvantages to renovated properties?

Points to watch include the risk of deterioration in structural components, unexpected additional construction costs, and the need to confirm earthquake resistance. Working with a reliable contractor is important.

Q. What should investors look for when buying a renovated property?

Location and the outlook for future rental demand are critical. If a property is close to a station and offers convenient access, renovation can support an increase in asset value.
