■ Background and Objectives of this Project
Shirahama Onsen in Wakayama Prefecture is counted as one of Japan's three ancient hot springs, alongside Arima and Dogo, and is one of the nation's leading hot spring resorts, attracting approximately 3 million tourists annually and 1.71 million overnight guests*1. In recent years, diverse tourism needs from both domestic and international visitors have increased, leading to a growing demand for high-quality accommodation spaces. However, the supply of new lodging facilities in the Shirahama Onsen area has been limited.
This project site boasts excellent access from Nanki-Shirahama Airport and JR 'Shirahama' Station, and is conveniently located close to major tourist attractions such as the scenic Shirarahama Beach. In addition to these locational advantages, all guest rooms will feature hot springs, and FFE (furniture, fixtures, and equipment) will be installed utilizing Misawa Homes' housing construction expertise, providing a more comfortable stay.
Misawa Homes and Wadakohsan position this facility not merely as accommodation but as a facility where the 'stay experience' itself is valued, against the backdrop of expanding long-stay tourism. By combining the strengths both companies have cultivated in residential businesses and other areas, they aim to create a rich and fulfilling stay environment where guests can enjoy the unique charm of Shirahama—its spectacular Pacific Ocean views and historic hot springs—with all five senses. Through the opening of this facility, they seek to generate new accommodation demand and attract repeat visitors to the Shirahama Onsen area, as well as contribute to the tourism promotion of Shirahama Town and Wakayama Prefecture as a whole by creating a new resort hub that brings further vibrancy to the region.

■ Features of the Facility
1. High-value private spaces with natural hot springs in all guest rooms
All 74 guest rooms will feature hot springs, allowing guests to fully enjoy the famous spring in a private setting. Approximately 70% of the rooms are planned to be ocean-view, designed to offer close-up views of the beautiful Kii Peninsula scenery.
2. Contribution to regional revitalization and response to new needs
This is a rare new hotel development project in the Shirahama area, the first in approximately 20 years. It aims to collaborate with Shirahama Town's 'Shirahama Onsen Town Revitalization Concept Promotion Plan'*2 to meet the active stay needs of anticipated groups such as female groups and families. By planning a room configuration suitable for multiple guests and comprehensive ancillary services, it will contribute to promoting long-stay tourism and further invigorating the regional economy.
3. Space creation using Misawa Homes' unique materials
FFE (furniture, fixtures, and equipment) will incorporate Misawa Homes' original materials. By applying the design and functionality cultivated in housing construction to the hotel space, the brand's unique value will be created.
