On August 7 a 3,572-square-metre city park reopened in Japan. It gained five plazas, a 226-metre elevated walkway and about 160 trees, and a four-storey steel building now stands inside it. The third and fourth floors of that building are a sauna. The city capped its own contribution at 46.6 million yen.
1.Meiji Park in Hakata Ward, Fukuoka, reopened on August 7, 2026. Four minutes on foot from JR Hakata Station, on a site of 3,572 square metres. The park first opened in 1965, when the surrounding land was reportedly still rice paddy and marsh.
2.The ground sat torn up for a long time after that. From 2008 onward, flood-control works, an underground power conduit and the station-front underground car park each occupied the site in turn, and although redevelopment began in 2011, only part of the park reopened in 2015. Fifteen years before the finished thing appeared.
3.Two things are new. A four-storey steel retail building of 1,588 square metres, and a 226-metre elevated garden path that loops around it and the lawn. Overall design supervision by Sou Fujimoto, architecture by Azusa Sekkei, construction by Asahi Komuten.
4.Planting covers 1,400 square metres, 39 percent of the site. Roughly 160 trees went in, all native species. Five plazas are scattered across what remains, each named with the suffix niwa, meaning garden: Nono-niwa is the central lawn, En-no-niwa the stepped seating, Yui-no-niwa the terrace, Sora-no-niwa the roof, and Machi-niwa the street frontage.
5.The elevated path starts at ground level, wraps two storeys and lands on the roof of the retail building. Stairs and ramps alternate, and the railings use thin closely spaced vertical bars, so the treetops below flicker in and out of view as you walk. On summer afternoons the deck drops shade onto the path underneath. Given an August afternoon in Hakata, that shade is dwell time.
6.The retail building is wrapped in vertical louvres, with terraces that curve in and out floor by floor. A ventilation tower for underground infrastructure stands on one edge of the site, and since it could not be removed, planting beds were wrapped around its base. At midnight the elevated path and the retail building close. The park floor stays open around the clock, and the upper levels reopen at 5:30 in the morning.
7.The park was built under Park-PFI, the public solicitation scheme in Japan's Urban Parks Act. A private operator builds revenue facilities such as restaurants and shops inside the park, then uses that income to develop the paths and plazas as well before handing them to the local government. A first for a park managed by the City of Fukuoka.
8.Fukuoka capped its own share at 46.6 million yen in the tender documents, a little over 440 million won. The operator won preferred negotiating rights in August 2023 and had its plan certified on June 14 the following year. The installation and management permit runs 20 years from the day the revenue facilities open.
9.What the operator actually spent has not been disclosed. Take 1.5 million yen per tsubo for a four-storey steel building of 1,588 square metres carrying bathing plant, and the retail block alone lands in the 700-million-yen range. Add the 226 metres of steel walkway, the plaza paving and the landscape, and the total sits somewhere near 1.1 billion yen. The city paid under four percent of that.
10.Floors three and four belong to TOTOPA, an urban spa. Admission is 2,980 yen for two hours, soft drinks and towels included, roughly 28,000 won. The two floors below hold the bakery Land Bageri, the Italian restaurant GABBI HAKATA, the cafe bar POSS COFFEE, the pizzeria 400℃ PIZZA Piu and the beer bar CONTINUE?, with one unit still empty.
11.Assume the spa takes 200 people a day and annual revenue lands in the 200-million-yen range. Apply a 15 percent operating margin, typical for urban bathing facilities, and about 30 million yen is left. Rent from the five units below, calculated at 12 percent of their sales, adds another 50 million or so a year.
12.Out of that come cleaning for 3,572 square metres, night security and landscape upkeep. Multiply what remains by 20 years and it barely clears the original investment. Add interest, depreciation and corporate tax and nothing is left. As a park business on its own terms, this does not make money. The same company went in a second time knowing that.
13.A park cannot hold people for long. Time on a bench is free, and free time yields no money. A two-hour ticket converts that free time into paid time. Somewhere to leave your bags and shower four minutes from Hakata Station is worth something to anyone changing shinkansen, too.
14.Something the same company had already tried in Tokyo. Toritsu Meiji Park, 1.6 hectares in front of the National Stadium, was the first Park-PFI project run by the Tokyo Metropolitan Government, and Tokyo Tatemono headed that consortium. It partially opened in October 2023, and the first TOTOPA arrived inside it on March 22 the following year. Pricing there is by the hour, starting at 1,980 yen. That branch took first place in the national sauna ranking the year after.
15.The payback sits outside the park. The location map issued by the operator also marks the Tokyo Tatemono Hakata Building, a few minutes north, a 9,828-square-metre office block completed in 1985 and one of the company's Fukuoka holdings. In June 2025 it broke ground on another office building of 5,129 square metres, eight minutes' walk from Hakata Station. The announcement that it was returning to Fukuoka office development after 16 years came after the park works had started.
16.An empty 3,572-square-metre lot four minutes from Hakata Station broke ground in autumn 2024 and came back as five plazas, 226 metres of walkway and one sauna, and the City of Fukuoka put up 46.6 million yen. Run the same numbers in Korea and the 20-year term is the first wall. Permits to use and profit from public property default to five years, and free use of donated property is capped at 20 years but in practice is cut far shorter. In a structure that barely recovers 1.1 billion yen over 20 years, halving the term means the arithmetic never closes. Whether a bathhouse can be classified as a park facility inside an urban park is a separate thing to check.
