The Former Hawaiian Kingdom Minister’s Villa is a historic building in Ikaho Town, Shibukawa City, Gunma Prefecture. It is part of a former summer villa once used by Robert W. Alwyn, the Hawaiian Kingdom’s Minister to Japan, at a time when Hawaii was still an independent kingdom.
Locally, the building has long been known as “Alwyn-san’s Villa.” Today, it is preserved and open to the public as a Shibukawa City-designated Historic Site. Very few buildings associated with the Hawaiian Kingdom remain in Japan, making this a particularly valuable piece of historical heritage.
The building combines traditional Japanese and Western architectural elements. The first floor has wooden flooring, while the second floor has traditional tatami flooring. This unusual combination reflects the cultural exchange taking place between Japan and the outside world during the Meiji era.
The villa was part of the summer residence used by Robert W. Alwyn, who served as the Hawaiian Kingdom’s Minister to Japan while Hawaii was still an independent kingdom. The surviving structure was relocated and restored in 2013, with great care taken to preserve its historical character.
Beginning in fiscal year 2014, the second floor was also opened to the public, allowing visitors to learn more about the building’s structure and history.
A guidance and exhibition facility on the grounds introduces the historical relationship between Ikaho and the Hawaiian Kingdom. The displays are organized around four main themes.

This section explains how the historic building was relocated, repaired, preserved, and eventually opened to the public.
Robert W. Alwyn lived in Japan during the Meiji era as the Hawaiian Kingdom’s Minister to Japan. After being introduced to Ikaho by Kaoru Inoue, a prominent Japanese government official of the time, he visited the area and became very fond of its mountain environment.
He eventually established a summer villa in Ikaho. Having married a Japanese woman, Alwyn continued to live in Japan for many years and remained there until his death at the age of 81.
For Alwyn, who was looking for a cooler retreat from Japan’s hot and humid summers, Ikaho’s mountainous location and relatively cool climate made it an ideal place to spend the summer. The building now open to visitors is part of the villa that once served this purpose.
This historical connection has continued to influence relations between the two regions. Today, Shibukawa City has a sister-city relationship with Hawaii County, Hawaii, and various cultural exchange activities take place between them.
Ikaho Onsen also hosts a Hawaiian Festival every summer, featuring hula dancing, music, and other elements of Hawaiian culture. These ongoing exchanges can be seen as part of the legacy of the historic connection between Alwyn and Ikaho.
One of the notable objects on display is the ceremonial saber that Alwyn wore on formal occasions. The elaborately decorated weapon is a valuable historical artifact that provides a glimpse into the life and status of a diplomat of the period.
The guard features an ornament shaped like the head of a phoenix. The metal fitting covering the mouth of the scabbard is decorated with the Alwyn family’s crest, known as Gosan-no-kiri, a traditional Japanese paulownia crest.
This artifact offers an especially interesting connection between the life of a Hawaiian diplomat in Meiji-era Japan and Japanese cultural traditions. Together with the other exhibits, it helps visitors imagine the personal and diplomatic exchanges that took place between Japan and the Hawaiian Kingdom.
The Former Hawaiian Kingdom Minister’s Villa can easily be included in a sightseeing itinerary around Ikaho Onsen. It is relatively close to the famous Ikaho Stone Steps, making it a convenient cultural stop while exploring the historic hot spring town.
For international visitors, the villa offers a particularly interesting perspective on Japanese history. It is a place where the histories of Japan and Hawaii intersect, providing an opportunity to learn about diplomacy, international exchange, and the cultural connections that developed during the Meiji era.
A visit to the villa also offers a different perspective on Ikaho, complementing the area’s famous hot spring culture with a story of international friendship and cultural exchange.
The villa is approximately 25 minutes by car from the Shibukawa-Ikaho Interchange on the Kan-Etsu Expressway.
From JR Shibukawa Station, take a Kan-Etsu Kotsu bus bound for Ikaho Onsen. The journey takes approximately 25 minutes. Get off at the final stop, Ikaho Onsen, and walk for approximately 10 minutes.
The Former Hawaiian Kingdom Minister’s Villa is a rare surviving reminder of the relationship between Japan and the Hawaiian Kingdom. Its traditional Japanese and Western architectural elements, historical exhibits, and connection with Robert W. Alwyn make it a distinctive cultural attraction in Ikaho.
When visiting Ikaho Onsen, taking a short detour to this historic villa provides an opportunity to look beyond the hot springs and discover the international history and cultural exchanges that have also shaped this mountain resort.
