THE BOTANICAL RESORT Hayashine, a stay-oriented complex created by renovating and repurposing a prefectural botanical garden in Naka, Ibaraki Prefecture, opened on 29 November 2025. It offers 45 accommodation units together with bathing and dining facilities. While the prefecture covered development costs, operations have been handled by the designated manager since 2025. Published prices are 3.2 times the prefectural average on weekdays and more than 4.4 times the average on Saturdays.
Ibaraki Prefectural Botanical Garden and Ibaraki Prefectural Forest were redeveloped by the private sector and reopened as Hayashine on 29 November 2025. The accommodation consists of 45 units in total, comprising 18 cottages and 27 glamping units. Admission was made free, and the site includes the Ofuro Café Rinne no Yu bathing facility, dining and a range of activities. Operations are handled by Botarashian Resort, a special-purpose company established in May 2024. The development plan and contract process from 2024 to 2025 put the total project cost at approximately ¥3 billion.
Under the business scheme, the prefecture pays the SPC development costs as consideration for services, while maintenance and operations are carried out for 20 years under a designated-manager arrangement based on the conditions of the public tender. The SPC was established on the premise of a group of 8 companies, with the Ikka Holdings group accounting for more than half of the equity contribution. A notable feature is that the SPC handles the design, construction and operation of the units as a single package.
Published prices average approximately ¥50,900 across all plans on Wednesdays and approximately ¥70,200 on Saturdays, reaching around 3.2 to 4.4 times the average published price of ¥16,100 across Ibaraki Prefecture. By unit type, the lowest prices are ¥16,800 to ¥19,200 for glamping on Wednesdays and approximately ¥30,700 on Saturdays. Within a 20-kilometre radius in the prefecture, there are approximately 6,400 rooms, but excluding Hayashine, much of the area has limited supply of family-oriented and extended-stay accommodation.
An estimate indicates that an ADR of approximately ¥55,000 would be required to recover the ¥3 billion total project cost from accommodation alone. If visitor spending within the garden is included, the required ADR falls substantially, and visitor spending of approximately ¥1,000 per person becomes key if 260,000 to 380,000 visitors spend money within the garden. The use of weekday and weekend price differences is positioned as the core of the business's profitability.
