Hakuba International School Review: Blending Nature with Sustainability Education

Hakuba International School (HIS) is a full-boarding international school that opened in 2022 in Hakuba Village, Nagano, at the foot of the Northern Alps. It offers a unique educational model in Japan, centered on "Human Flourishing" and built on three pillars: Project-Based Learning (PBL), Social and Emotional Learning (SEL), and Outdoor Education.

For the 2025-26 school year, there are approximately 60 students, 25 teachers, and 4 interns, resulting in an impressive student-to-teacher ratio of about 2.4:1. The school is scheduled to have its first graduating class in 2027, placing it in a phase where "potential and unknowns coexist."

In this article, from the perspective of ELT (founded in London, 1984), we will cross-reference official information from HIS with administrative documents from Nagano Prefecture to honestly examine the gap between its "philosophy" and "reality." We will address the core parental concern—"I'm interested, but is a new school a safe choice?"—with data and facts.

Hakuba International School (HIS) Basic Information

School Overview

HIS's journey began in 2015 when founder Tomoko Kusamoto started running summer programs. Witnessing the transformative effect of Hakuba's natural environment on children, she officially opened the full-time boarding school in August 2022. It received its official 'Miscellaneous School' status from Nagano Prefecture in April 2024.

Access and Location

Hakuba Village is about 3-4 hours from Tokyo via the Hokuriku Shinkansen and a local train line. The school is located in front of a ski resort and has a school forest of approximately 33,000 square meters just a 3-minute walk away.

The natural environment of Hakuba is the essence of HIS's education. In winter, activities like skiing, snowboarding, and digging snow caves become part of daily life. From spring to autumn, students engage in hiking, rafting, mountain biking, and fieldwork in the forest. However, families should be prepared for the climate, as winter temperatures can drop below -10°C (there are records of students camping outdoors at -11°C).

Educational Model: What is the "Human Flourishing Curriculum"?

The Three Pillars of Education

HIS's educational approach is fundamentally different from the traditional "textbook → test → standardized score" model. The curriculum is structured around three domains: Foundational Literacies, Competencies, and Mindsets. Student progress is documented in a portfolio called the 'HIS Learning Passport'.

PBL (Project-Based Learning) — Learning by 'Actually Building'

HIS's PBL is designed for students to acquire academic knowledge through real-world projects, rather than learning theory in a classroom and being assessed by tests.

For example, as featured on the official website, students undertook a project to design and build a "warm, dry, and sustainable winter shelter" in the school's forest. They integrated indigenous wisdom, modern architecture, and physics principles to complete a shelter large enough for a group to stay in for two nights. In another project, they learned physics principles by designing a rocket that could land a raw egg without breaking it. This approach of learning through a "build → test → improve" cycle is consistent throughout the curriculum.

SEL (Social Emotional Learning) — Cultivating Non-Cognitive Skills

SEL is described in Nagano Prefecture's administrative documents as a key feature of the school's education, focusing on "learning to acquire non-cognitive skills such as interpersonal relations and emotional management." While the official website does not detail the specific weekly hours or evaluation methods, the boarding life itself is designed as a practical ground for SEL.

Outdoor Education — All of Hakuba is the Campus

HIS has a unique academic calendar where six-week intensive learning periods (called "bursts") are interspersed with holidays or "week-long expeditions into nature."

During the winter's Winter Camp, in addition to skiing and snowshoeing, students participate in a program where they dig and sleep in their own snow caves. In autumn, each grade undertakes a purposeful expedition (e.g., long-distance trails, Hakuba backcountry hiking, multi-day river journeys), and in spring, they go on learning trips to various parts of Japan.

Academic Reality: The Offering of AP Courses

It's natural to ask, "Are PBL and outdoor activities enough to ensure academic rigor?"

HIS requires a minimum of 42 credits for graduation (1 credit = 1 course per semester). The schedule consists of six courses per day for four days a week, with one day dedicated to off-campus projects and applied learning.

Notably, HIS offers AP (Advanced Placement) courses. According to the 2025-26 course booklet, available courses include Pre-Calculus, Calculus AB/BC, AP Seminar, AP Research, AP Macro/Micro Economics, and AP Japanese. Since AP is a widely recognized qualification for university admissions in the United States, this helps to dispel concerns that HIS's unique curriculum might be academically insufficient.

Furthermore, HIS is a member of the Mastery Transcript Consortium. This is a system that provides universities with competency-based transcripts as an alternative to traditional GPA/report cards, and it is gaining traction, particularly in the US.

Sustainability Education — Confronting the Climate Crisis with Systems Thinking

HIS's sustainability education goes beyond the basic "let's pick up trash" level of environmentalism. The academic framework is designed by a team trained in MIT's "Compassionate Systems Framework," which uses nature observation to cultivate systems thinking.

Operationally, administrative documents show that the school itself practices sustainability through compost management, insulation retrofits for school and dorm buildings, and the installation of pellet stoves. The changing snowfall patterns and ecosystem shifts in Hakuba are used as "teaching materials," providing an environment where climate change is learned not as abstract knowledge but as a daily, tangible experience—a unique strength that only HIS offers in Japan.

Language Education: English + Compulsory Japanese

The primary language of instruction is English. All students take Japanese classes based on their proficiency level. Japanese is compulsory for all three years of Middle School, and students in the upper grades must study Japanese for at least one year. Language support is also available for non-native English speakers to improve their reading, writing, and speaking skills.

Status of IB and WASC Accreditation — The Most Critical Point to Verify

IB: Currently Not an Authorized or Candidate School

One of the biggest concerns for parents is the school's International Baccalaureate (IB) accreditation status.

As of March 2026, HIS is not an authorized IB World School, nor is it listed as a candidate school on the official list from the MEXT IB Education Promotion Consortium (as of December 31, 2025).

While some older articles mention plans to open as an "IB-based" school, this reflects the initial concept from around 2017-2018. The current HIS has adopted a different approach: offering AP courses combined with its unique Human Flourishing Curriculum.

WASC: 'In the Accreditation Process'

The official Quick Facts page states that HIS is in the process of accreditation by WASC (Western Association of Schools and Colleges). WASC is a regional accrediting agency for schools in the western United States, and obtaining this accreditation is a crucial turning point, as it can affect university entrance qualifications in Japan.

Japan's Ministry of Education, Culture, Sports, Science and Technology (MEXT) has established that completion of a 12-year program at an educational facility with international accreditation from bodies like WASC, CIS, or ACSI can be recognized for university entrance qualifications. In other words, if HIS successfully obtains WASC accreditation, it could open up pathways for graduates to apply to Japanese universities. Conversely, if accreditation is not obtained, the routes for applying to Japanese universities will be limited.

Impact on Graduation Qualifications: Three Questions Parents Should Ask

As a 'Miscellaneous School,' HIS does not grant a Japanese high school diploma. It also does not currently offer the IB Diploma. How students will navigate university admissions without these qualifications is a critical point to consider before enrolling.

Parents should directly ask HIS the following three questions:

① When is WASC accreditation expected? — Please confirm the specific stage of the process (e.g., before the site visit, at the candidacy stage).

② With what qualifications and transcripts will the first graduating class of 2027 apply to universities? — Please confirm the design of the application documents, such as AP scores, the Mastery Transcript, and HIS's own diploma.

③ For students wishing to apply to Japanese universities, what specific pathways are available? — Please confirm alternative plans in case WASC accreditation is not obtained (e.g., prior consultation with individual universities, transferring via an overseas university).

Tuition and Fees Overview [Official 2026-27 Data]

Annual Fee Breakdown

The following fee data for the 2026-27 school year is from the official Admissions Process page.

Estimated total for the first year: For a high school boarder, the annual fee of ¥7,130,000 + registration fee of ¥300,000-¥500,000 + application fee of ¥25,000 = approximately ¥7.45 to ¥7.55 million.

Cost Comparison with Other Schools

HIS's fees are comparable to UWC ISAK and lower than Harrow Appi and RSJ. However, the official website does not specify what is covered by the Maintenance & Equipment fee (¥530,000), such as meals, equipment, or insurance, so this should be confirmed before enrollment.

Scholarships and Financial Aid

The official Giving FAQ states that "tuition covers only a portion of the actual cost, and over 60% of the annual budget is funded by donations," and that "donations make it possible to offer scholarships." This indicates that HIS operates as a non-profit reliant on donations, and it is highly likely that a scholarship system exists.

However, the official website does not provide specific details such as whether the aid is need-based or merit-based, the award rates, or past results. Families considering applying for scholarships should inquire directly with the Admissions Office.

Admissions Process and Required English Proficiency

Application Process

HIS uses a rolling admissions process, with the following steps:

1. Submit Inquiry Form — Send the inquiry form from the official website
2. Submit Documents — Application, Transcripts, and Recommendations
3. Zoom Interview — An online interview
4. Admissions Decision

While the school year typically begins in August, a small number of mid-year admissions are also accepted.

Recommended English Proficiency by Grade

HIS has officially published its recommended English proficiency levels. While submission of standardized test scores is not mandatory, the following are guidelines:

The school states that "fluency is not required, but students should be prepared to participate in complex classroom discussions conducted entirely in English." English proficiency is assessed holistically using conversation, live writing samples, and academic records.

Pop-Up School (Trial Enrollment)

HIS regularly holds "Pop-Up Schools" as part of its Admissions Events. For a fee of ¥25,000, participants can experience a simulation of the HIS learning environment on the Hakuba campus. Information sessions are provided with simultaneous English and Japanese interpretation.

For families seriously considering enrollment, attending a Pop-Up School is almost essential. It is an opportunity to see firsthand whether the Hakuba location and the PBL learning style are a good fit for your child.

Benefits and Risks of a New School — An Honest Analysis

Benefits

An exceptional 2.4:1 student-to-teacher ratio. With approximately 60 students to 25 teachers and 4 interns, this ratio is overwhelmingly better than any other boarding school in Japan, meaning each student receives close attention.

The opportunity to be a 'founding member' of the school culture. As a new school, its culture is not yet set in stone, allowing students to participate in creating the school's traditions and rules. This is an extremely valuable experience not available at established schools.

A rapid curriculum improvement cycle. New schools are constantly improving and evolving their curriculum each year. Areas that would take a long time to change in large, established schools can be quickly improved at HIS based on feedback from teachers and students.

Education-first decision-making, characteristic of a non-profit. The fact that over 60% of the annual budget is covered by donations means the management structure is geared toward maximizing educational quality rather than maximizing tuition revenue.

Risks

No graduating class yet. The first class is scheduled to graduate in 2027, but as of now, there is no university placement record. It is not possible to judge the school based on "which universities students get into."

No IB DP accreditation.
HIS is not listed on the MEXT's list of IB authorized or candidate schools. While the initial concept included an IB-based plan, the school now follows a different path with AP + a unique curriculum. If obtaining the IB Diploma is a priority, HIS is not an option.

WASC accreditation is 'in process' but not yet granted.
WASC accreditation is a crucial factor affecting eligibility for Japanese universities, but it has not yet been obtained. The uncertain timeline for accreditation is a risk for families considering Japanese universities.

Does not grant a Japanese high school diploma. As a miscellaneous school, it does not provide a Japanese high school graduation certificate. Students cannot take the general entrance examinations for Japanese universities (Common Test + individual university exams).

Limitations of a 60-student community.
While the small size offers personalized attention, it also has downsides, such as having only 10-15 peers in the same grade, limited options for extracurricular clubs, and a smaller sample size for diversity.

Structural risks in teacher recruitment.
Nagano Prefecture's administrative documents point to concerns that a prolonged weak yen could make it difficult to secure overseas talent, and that rising land prices and a shortage of rental housing in Hakuba Village pose challenges for securing teacher accommodation.

How to Approach the 'Risks' — ELT's Perspective

The risks of a new school are not something to be avoided, but rather something to be understood before making a decision. Please confirm the following five questions with HIS before enrolling:

1. What is the specific progress and expected timeline for WASC accreditation?
2. What specific documents will the first graduating class of 2027 use to apply to universities?
3. Are there any other international qualifications, besides AP courses, that you plan to offer in the future?
4. What is the tuition refund policy for withdrawal or transfer if the school is not a good fit? (The official policy states, "Fees are non-refundable.")
5. What is the teacher retention rate and what are your future teacher recruitment plans?

Additionally, we strongly recommend participating in the Summer School 2026 as a 'trial run.' This two-week program allows you to verify whether the Hakuba environment and HIS's learning style are a good fit for your child before committing to enrollment.

Boarding Life and Daily Life in Hakuba

Dormitory Overview

HIS has two dormitories, "Blanche" for girls and "Miyama" for boys, housing about 50 students. Blanche, which opened in August 2022, is a renovated traditional Japanese inn equipped with a kitchen and study spaces.

Teachers also reside on campus, fostering a "family-like" community thanks to the small school size.

The Four Seasons of Hakuba and the Reality of Daily Life

Winter (December–March)
Skiing and snowboarding literally become part of daily life. Supervised skiing is offered every Saturday and Sunday during the winter, in addition to one other weekend activity. The Winter Camp also includes a program where students dig and sleep in snow caves.

Autumn (September–November)
Grade-specific expeditions are conducted. These include challenging experiences like long-distance trails, backcountry hiking, and multi-day river journeys. The official blog features student reflections on the autumn camp, sharing real experiences like "no shower for five days" and "getting soaked in the rain."

Spring (April–June)
Learning trips to various parts of Japan are organized, with older students challenging themselves with expeditions to more distant locations.

Summer School 2026 — The Best 'Trial Run' for Prospective Students

Dates: Monday, July 6 – Friday, July 17, 2026 (2 weeks) Theme: "Flourishing People, Flourishing Planet" / "Sustainability in Action" Target: Equivalent to Grades 6–9 Fee: ¥575,000 (Full board. Includes accommodation, meals, materials, insurance, and planned activities. Round-trip transportation is separate.) Cancellation Policy: Full refund (less bank transfer fees) until May 31; no refund from June 15 onwards.

The summer school is an interdisciplinary program combining science, music/art, systems thinking, and outdoor activities, allowing participants to experience PBL in Hakuba's natural setting. As spots are limited, early application is recommended.

How HIS Differs from Other Boarding Schools

HIS occupies a unique position, different from the "British elite education" model of Harrow Appi and RSJ, and also distinct from the "diversity and leadership" focus of UWC ISAK. Its model is centered on "natural environment x sustainability x project-based learning." This concept is similar to Green School Bali (Indonesia), and no other school of this type currently exists in Japan.

Conclusion: Who is HIS a Good Fit For?

HIS is likely a good fit for families who:

• Question standardized test-driven education and resonate with a "learning by doing" approach like PBL, SEL, and outdoor activities.
• Have a child who loves nature and is comfortable with physical activity.
• Are primarily considering overseas university pathways and have a low dependency on the Japanese general university entrance system.
• Have the resolve and flexibility as a family to bet on the "potential" of a new school.
• Want their child to be raised in a small, "family-like" community.

Families who should consider carefully:

• Strongly desire their child to attend a Japanese university (especially via the general entrance examination route).
• Consider IB DP accreditation a prerequisite for enrollment.
• Value the security of an established school with a proven track record of university placements.
• Are concerned about their child's ability to adapt to the cold winter environment and physically demanding outdoor activities.
• Feel that a community of 60 students is too small (in terms of clubs, number of peers, etc.).

The First Step: First, participate in a Pop-Up School or the Summer School 2026 (July 6-17, ¥575,000) to see for yourself if the Hakuba environment and HIS's learning style are a good match for your child. Experiencing the school's atmosphere, which cannot be understood from the website alone, is the most reliable way to make a decision.
