9 Sustainable Hotels in Tokyo: Choosing Accommodations Based on Third-Party Certifications and Concrete Initiatives

When you want to stay at a sustainable hotel, have you ever felt uncertain about what criteria to use when choosing one?

Even when a property claims to be “environmentally friendly,” it can be difficult to see the evidence behind such statements or to judge how seriously they’re committed to these efforts. Choosing where to stay—even for just one night—is connected to various impacts, including water and energy usage, amenity waste, and engagement with the local community.

This article focuses on hotels in Tokyo that have obtained international certifications from private third-party organizations, or facilities that disclose their initiatives in relatively detailed ways on their official websites.

I’ve compiled this information so you can compare options while thinking about what matters most to you.

*Note: The information in this article is primarily based on publicly available information from 2024. Since many certifications require renewal, please check each hotel’s official website for the latest certification status and current initiatives.

Criteria for Selecting Hotels in This Article

Our editorial team selected hotels based on the following perspectives:

Third-Party Certification Status

Hotels that have obtained and publicly disclosed certification programs for accommodations, such as “Sakura Quality An ESG Practice” (a GSTC-approved standard for lodging facilities), the internationally recognized environmental certification “Green Key,” and “Eco Mark (Hotels and Inns)” operated by the Japan Environment Association.

Transparency of Information Disclosure

When using terms like “sustainable” or “eco,” does the hotel provide supporting evidence such as specific certification names, evaluation details, or numerical targets?

Amenity and Resource Management Policies

Does the hotel clearly state specific operational measures such as eliminating or reducing disposable amenities, recycling efforts, or going paperless?

Consideration for Local Communities and Supply Sources

Does the hotel publicly share social and economic initiatives such as participation in local events, farm-to-table practices, or adoption of fair trade products?

This information is primarily based on first-hand sources such as official websites and press releases that were available at the time of writing.

What to Know When Comparing Certifications and Initiatives

The Meaning of Third-Party Certification

Certifications such as “Sakura Quality An ESG Practice,” “Green Key,” and “Eco Mark” are not just self-declared by hotels but are awarded after review and on-site inspections by third-party organizations. This provides some assurance for the validity behind the word “sustainable.”

However, the absence of certification doesn’t mean a hotel lacks environmental consideration. Obtaining certification requires cost and time, so some facilities operate according to their own standards. Additionally, some small inns and guesthouses may not fit into certification systems but continue community-based initiatives.

Since many certifications require renewal, it’s important to verify acquisition dates and validity periods.

Perspectives on Amenity Elimination and Reduction

Eliminating or reducing disposable amenities is considered one plastic waste reduction measure recommended by many public agencies and NGOs. On the other hand, some guests may find it inconvenient when they “can’t bring their own” or “forgot” to pack these items.

Some facilities have switched to request-based or paid provision systems, so checking before booking can provide peace of mind.

Background of Numbers and Terminology

This article introduces information such as “recycling rate,” “CO2-free electricity,” and “fair trade” officially announced by each hotel, but each term has the following background:

Recycling Rate: The meaning of the number changes depending on the scope (all waste or specific categories), calculation method, and year. In Japan, thermal recycling (heat recovery during incineration) is often included, which differs from material recycling emphasized in Europe and other regions.

CO2-Free Electricity: Utilizes mechanisms such as FIT non-fossil certificates and is not necessarily 100% physically renewable energy.

Fair Trade/Certified Products: Meaning differs depending on which certification scheme is used and the scope of adoption.

When these details are not clearly stated on official websites, we recommend contacting the hotel directly if you have concerns.

The Meaning of Lack of Information Disclosure

The facilities introduced in this article are limited to those that publicly disclose certifications and initiatives on official websites or press releases. For facilities with insufficient information disclosure, we cannot determine whether they’re “not implementing initiatives” or “simply not publicizing them,” so they are not included.

Considering Other Options

Consider Your Travel Purpose

Reviewing your travel purposes and frequency and limiting travel to only truly necessary trips is one potential way to reduce environmental impacts such as CO2 emissions from transportation. However, since this relates to impacts on the tourism industry and local economies, there isn’t necessarily one single correct answer.

Contact Hotels Individually, Even Without Certification

Even when information isn’t available on official websites, directly asking hotels about their “amenity provision policies” or “environmental initiatives” can sometimes reveal their operational approach.

Choose Regional Small-Scale Accommodations

Rather than large chains, choosing small inns or guesthouses rooted in local communities may allow for stays that emphasize contribution to the local economy and engagement with the community.

Final Thoughts

As shown in the examples introduced in this article, there are several hotels in Tokyo that have obtained third-party certifications or officially publish their environmental consideration and social contribution initiatives.

No hotel is perfect—each has areas of strength and aspects that haven’t yet been disclosed.

Which hotel you should choose depends on “what matters most to you”—whether that’s certification status, amenity policies, community engagement, price range, location, or transparency of information disclosure.

I hope this article serves as one resource for your own decision-making.
