Introduction

In a strategic collaboration, Itandi Inc., a company dedicated to smoothing real estate transactions through technology, and Nowcast Inc., a leader in providing next-generation financial infrastructure, have embarked on an innovative project to develop a new rent index based on substantial big data gathered from real estate rental transactions. Utilizing Itandi's platform, which includes a real-time inter-broker site known as "ITANDI BB," this initiative aims to create a rental index that will precede public statistics in terms of timeliness and effectiveness.

Background and Purpose

The current landscape of the real estate rental market in Japan reveals a significant gap: comprehensive public databases that provide access to reliable rent trends and vacancy rates are severely lacking. This absence complicates the ability of market participants to grasp fundamental information crucial for effective decision-making. Existing public statistics often fall short of capturing real-time movements in the rental market, even though rent constitutes a significant portion of consumer prices. Previous methods of monitoring rent trends have not been robust, highlighting a pressing need for accurate, accessible data.

This new index will combine primary rental data collected by Itandi from approximately 4,800 real estate management and brokerage companies nationwide with Nowcast's advanced data analysis technology. The objective is to develop a leading indicator that captures the initial fluctuations within the rental market, thereby complementing formal public statistics such as the Consumer Price Index (CPI).

Characteristics of the New Index

1. Early Detection of Rent Trends: Unlike traditional public statistics, this new index allows for early detection of changes in rent trends that might otherwise go unnoticed.
2. Utilization of Repeat Rent Methodology: This innovative approach tracks rent variations for the same properties over time, facilitating updates on the latest rental trends.
3. Understanding Rent Determinants: The index explores structural differences in rent trends between new and existing tenants, providing insights into the broader mechanisms driving rent decisions.
4. International Comparability: Developed according to global standards, this index is designed for international comparisons, making it a valuable tool for global market assessments.

Prototype Analysis Examples

1. Repeat Rent Index (Year-on-Year Trends): By tracking rent for identical properties over time, the prototype reveals a recent year-on-year increase of approximately 4% to 5% for rents, indicating an upward trend.
2. Trends in New Rental Contracts: Monthly data categorizing new rental agreements as raised, lowered, or unchanged shows a significant increase in rent hikes, growing from about 30% in early 2023 to nearly 60% recently, suggesting a shift in market norms.
3. Rent Change Rates for New Contracts: Monthly summary of rent changes between outgoing and incoming tenants indicates an upward trend, expanding to an average increase of around 5%, affirming a consistent rise in rental prices each time a new contract is executed.

Commentary from Nowcast's Founder

According to Tsutomu Watanabe, founder and executive director of Nowcast and a professor at the University of Tokyo, there is a palpable increase in rental prices centered around Tokyo, likely extending to other urban areas. This context amplifies the demand for precise rent indicators both domestically and internationally. The complexities in creating a reliable rent index reside primarily in two aspects: the infrequency of rent adjustments, limiting the opportunities for change, and the substantial variability in real estate attributes such as size and access to transportation. The current initiative aims to tackle these challenges through innovative methodologies, including probability models and the repeat rent approach. It is envisioned that this index will set a new standard, catering to the stringent requirements posed by investors from Japan and beyond.

Future Outlook

Itandi and Nowcast are committed to advancing the joint development of the rent index while expanding the coverage in terms of area and property types to enhance its accuracy. Additionally, they aim to provide evidence-based data reflecting the realities of the rental market to policy-making organizations, thus contributing to Evidence-Based Policy Making (EBPM). Collaborative efforts will also be focused on developing data utilization services for the real estate sector and financial institutions, striving towards increased transparency in the rental market and the growth of the industry.
