The Equipment necessary for STR Business

Equipment investment is one of the most critical factors determining success or failure when starting an STR (Short-Term Rental) business. Appropriate equipment investment not only ensures legal compliance and operational stability but also directly leads to improved guest satisfaction and higher nightly rates.

This article divides the equipment investment required for STR operations into three categories: "Legally Mandated Equipment," "Minimum Facilities Required for Accommodation," and "Premium Equipment (for Premium Positioning)," providing detailed explanations of specific requirements and investment estimates for each. Use this guide to establish a realistic budget for your initial planning.

1. Legally Mandated Equipment (Essential Safety and Fire Prevention Equipment)

To operate an STR legally, you must meet equipment standards established by laws such as the Hotel Business Law, Fire Service Law, and Building Standards Law. These facilities are designed to protect guests' lives and cannot be compromised.

Estimated Investment: Approximately ¥5,000,000

When undertaking minimum renovations required by law (particularly for buildings with 3 or more stories, such as installing fire-rated partitions and fire doors), equipment investment typically reaches approximately ¥5,000,000.

Fire Prevention Equipment (Automatic Fire Alarm Systems, Fire Extinguishers, Emergency Exit Signs)

Fire prevention equipment installation is mandated by the Fire Service Law based on the scale and structure of the accommodation facility.

Automatic Fire Alarm Systems are required for owner-absent minpaku (short-term rental accommodations), guest rooms exceeding 50 square meters, or buildings with 3 or more stories. However, for single-family homes with 2 stories or fewer and total floor area under 300 square meters, "special small-scale facility automatic fire alarm systems" using wireless sensors often suffice, allowing for cost reduction.

Fire Extinguishers are mandated for facilities with total floor area of 150 square meters or more, though installation on each floor is strongly recommended even for smaller facilities for safety reasons. Proper placement includes areas near cooking facilities and along evacuation routes within a 20-meter walking distance.

Emergency Exit Signs are critical equipment that must function even during power outages to guide occupants to exits and evacuation routes. These include "exit signs" positioned directly above exits like entrances and "corridor signs" placed at corridor corners. However, for buildings with simple, clear layouts where guests can immediately see an exit upon leaving their rooms, installation may be waived at the discretion of the local fire department.

Fire Prevention Equipment Based on Building Standards Law

Safety standards related to building structure are equally important. Particularly for buildings with 3 or more stories used as accommodation facilities, the Building Standards Law requires the formation of fire-rated vertical shafts and installation of fire-rated doors to prevent fire spread to upper floors. Partitioning work for stairwells and similar areas typically requires investment in the millions of yen, necessitating careful evaluation during property selection.

Other Safety Equipment

Installation of carbon monoxide detectors is essential, particularly for facilities using gas appliances or heating equipment, to prevent carbon monoxide poisoning. Additionally, installation of emergency lighting for power outages and posting of evacuation route diagrams in guest rooms and common areas are basic legal requirements for ensuring guest safety.

2. Minimum Facilities Required for Accommodation (Budget-Tier Facility Level)

After meeting legal requirements, the next step is providing basic accommodation functionality. While these facilities enable STR operation, this level typically results in limited differentiation from competitors, potentially leading to budget-tier positioning with price competition.

Estimated Investment: Approximately ¥1,000,000

Depending on the existing condition of the building, minimum facilities can often be established for approximately ¥1,000,000.

Bedding and Sanitary Facilities

Beds and bedding form the core of accommodation facilities. Provide clean sheets, comforters, and pillows (at least one per guest). Note that standards such as HVMB (High-Value Minpaku Business) typically prohibit studio-type units, requiring at least one-bedroom independent sleeping areas.

Toilets must be provided in appropriate numbers relative to guest capacity. A minimum ratio of one toilet per six guests is recommended, with one per four guests being ideal. While Japanese or Western-style toilets are legally acceptable, modern guest expectations typically require clean Western-style toilets with heated seats.

Shower and bathing facilities should include at least one, with one per four guests being ideal. Hotel Business Law does not necessarily require bathtubs; shower facilities alone can satisfy licensing requirements.

Kitchen and Appliances

One of STR's major attractions is the ability for guests to prepare their own meals. Therefore, refrigerators (even small ones), microwave ovens, and electric kettles are minimum appliances to provide.

However, to list a property as having a "kitchen" on platforms like Airbnb, more than just a microwave and mini-refrigerator is required. A full kitchen environment with a stovetop, oven, and basic cooking utensils is necessary.

Linens and Basic Amenities

Essential items include linens (bath towels, hand towels) and basic bath amenities (shampoo, conditioner, body soap), hand soap, and toilet paper for guest comfort. Hair dryers are also considered essential basic equipment in modern accommodation facilities.

3. Premium Equipment (Premium Positioning and Differentiation Investment)

By moving beyond minimum requirements and providing guests with "special experiences," you can increase nightly rates and maintain high occupancy. Selecting appropriate investment levels based on location and target guest demographics is crucial.

Estimated Investment: Approximately ¥5,000,000 to ¥30,000,000

• Urban Premium Upgrades (approximately ¥5,000,000): For urban properties, approximately ¥5,000,000 in cosmetic renovations (wallpaper, flooring replacement, partial bathroom updates) and furniture/appliance upgrades are considered essential.
• Resort Destination Premium Development (additional approximately ¥30,000,000): For resort locations targeting premium pricing, full equipment updates, landscaping, outdoor space development, and special amenities such as hot tubs, hot springs, and saunas are necessary, requiring additional investment of approximately ¥30,000,000.

Enhancing Comfort Through Furniture and Space Design

Creating a space for enjoying the stay itself, rather than merely sleeping, requires investment in the living area. Installation of comfortable high-quality sofas and large dining tables for group dining and conversation significantly enhances facility appeal.

Additionally, introducing large smart televisions (compatible with streaming services like Netflix and Amazon Prime Video) elevates the in-room entertainment experience.

Hotel-Quality Abundant Amenities

Upgrading basic amenity quality is also effective. Providing premium brand bath amenities, high-quality linens, and comprehensive coffee and tea selections (such as Nespresso machines) creates a luxury hotel atmosphere.

Design and Concept Cohesion

The most powerful differentiation factor is interior design investment. Creating spaces with clear concepts—such as Japanese modern design reflecting regional characteristics or sophisticated Scandinavian design—through careful selection of furniture, lighting, and artwork dramatically improves listing photography appeal, directly increasing booking rates and premium pricing potential.

Conclusion

For STR operations, balancing "defensive investment" for legal compliance with "offensive investment" for revenue enhancement is essential. First, ensure comprehensive safety equipment meeting fire prevention and building standards with approximately ¥5,000,000 investment. Then, based on location (urban versus resort) and target guest demographics, implement premium equipment investments (¥5,000,000 to ¥30,000,000 range) to achieve sustainable, high-revenue STR operations.
