■ 'Overwhelming Authority' and 'Power of Continuity' Trusted by Government Agencies

While information regarding the share house industry exists on the internet and elsewhere, much of it has ambiguous research methods or sources, and the reality is that reliable data that can truly be 'used' in practice is extremely scarce.

That is precisely why the 'overwhelming reliability' and 'continuity' of this report shine. This market research report aggregates the latest trends and developments in the share house market across Japan and is widely used by government agencies, research institutions, and a wide range of industry stakeholders.

And, what is worth noting is the fact that this statistical survey has been conducted and prepared with the cooperation of 'Mitsubishi UFJ Research and Consulting Co., Ltd.' every year since its initial publication.

With one-off surveys or data from ambiguous sources, accurate market trends cannot be seen. Because they have continued to accumulate data over many years using the same high standards as Japan's leading think tanks, they are able to highlight accurate 'market trends' that are not just a passing fad.

In the share house industry, where ownership and operators change frequently, efforts are made every year to improve the accuracy of continuous research methods, and the precision of the data and the depth of the analysis are at an extremely high level that is unparalleled in the industry.

■ What is the strict definition of a 'share house' in statistics in the first place?

Before entering into specific topics, let us confirm the strict definition of the word 'share house' as a premise for correctly understanding the market. It is important to distinguish whether it is 'temporary lodging' or 'continuous residence'.

The Japan Share House Association defines a 'share house' for statistical purposes as follows.

・Definition of a share house

・The significance of 'at least 1 month'

Why is a period of '1 month' the dividing line? This is not just a definition of words, but because there is a clear distinction in Japanese law.

In practice, the repeated and continuous provision of stays for 'less than 1 month' is,in principle, subject to the 'Hotel Business Act' (or the Private Lodging Business Act = subject to Minpaku)and is treated as a 'lodging facility'. On the other hand, by assuming a contract of 1 month or more and regarding it as the base of one's life, it can be treated as a subject of a lease contract based on the 'Act on Land and Building Leases', etc., that is, as a 'residence'.

・Things that are similar but different: Comparison with guesthouses (simple lodging facilities)

A term often confused with share houses is guest house. There are clear differences between these in terms of market statistics, legal classification, and purpose of use.

The biggest difference is likely the contractual form based on legal classification. Since share houses are premised on 'residence,' they use a 'lease agreement' based on the Act on Land and Building Leases.
On the other hand, guest houses are classified as a 'lodging business' based on the Hotel Business Act and similar laws, so a front desk and guest registry are required (along with other facility conditions), making the activities involved completely different both legally and practically.

■ What exactly is written in it? (Topic Explanation)

As this report is a paid document, I will refrain from mentioning specific figures, but I will introduce the topics so that you can understand the overview of the report. The challenges currently faced by operators and industry trends are visualized through data.

1. Visualization of nationwide location status and trends

It covers not only the current status of the number of buildings, rooms, and beds on a nationwide scale, but also the ratio of dormitories to private rooms, and the distribution by capacity (from small-scale to large-scale properties). When compared with past data, year-over-year changes such as 'which property size is trending' can be clearly read.

2. The intersection of macroeconomics and share house demand

A highlight of this report is that it does not stop at mere real estate data but adds deep commentary from a macro perspective.

It touches on concerns such as the weak yen, construction costs, and soaring energy costs, as well as the potential for increased demand for medium- to long-term stays related to foreign worker legislation.

3. Changes in business styles and real estate DX

The industry association has conducted interviews with member operators, as well as surveys on operator awareness and trends. It points out the current situation where the value required of share houses is shifting, and also addresses the necessity of DX (Digital Transformation) for streamlining management operations.

Summary | As a strategy formulation possible only in the AI era

Once you obtain this report, it would be a great waste to just read it once and be done with it. Now that AI (Artificial Intelligence) has become business infrastructure, I propose using this statistical material as 'industry knowledge' and applying it with specific ideas.

The most effective method is to have an AI tool (such as NotebookLM) read the data in this report along with the 'property information' and 'past inquiry history' that your company accumulates daily, and incorporate it into your own AI database.
This enables high-level 'brainstorming, analysis, and evaluation' specialized for your own properties in an instant, which could never be obtained by simply looking at statistics.

The macro data accumulated by the federation over many years and the advanced processing power of AI are added to the areas where share house operators have previously relied on 'intuition and experience.'
This is 'data-driven' share house management. This report is not just an industry market survey, but should serve as an extremely powerful input material for shifting your business to the next generation.
