FEATURE: Tokyoites push back against IT giants' encroaching data behemoths
Discontent is growing in the Tokyo metropolitan area due to proposals to construct giant data centers in residential areas, with industry groups working to smooth relations between locals concerned about the "eerie" facilities' imposing nature and the companies that operate them.
Despite tech companies investing heavily to build the massive digital hubs to meet the storage and processing demands of cloud computing and artificial intelligence, some projects are being scrapped due to opposition from residents worried about electricity shortages, heat islands and obstruction of their natural light.
In the city of Hino in Tokyo, a billboard announced the construction of three data centers, including a five-story, 72-meter-tall building scheduled for completion in 2031. As the tallest structure in the city, it would be the area's proverbial sore thumb.
A residential association is demanding the project be paused until the plan conforms to a city ordinance that limits the height of apartment buildings to 25 meters.
The facility, which will require tight security, would also consume a massive amount of electricity and generate significant levels of heat.
"They haven't given us an acceptable explanation," said resident association head Eizo Tsutsumizaki, 71, referring to the project owner Mitsui Fudosan Co., Ltd.
Mitsui Fudosan is now considering whether the building's height can be reduced. As a tradeoff, it also plans to build a new park and sidewalk on the site to accommodate the community.
In Inzai, Chiba Prefecture, home to many data centers, the city was flooded with calls of concern in April when plans were revealed for an over 50-meter-tall building housing a data center in a prime location in front of a station.
It would add a new and imposing structure to the area, which already hosts 114 data centers, according to datacenter.com.
Mayor Kengo Fujishiro wrote on social media, "This place is the center of civic life. It is not an appropriate location for this facility."
In Nagareyama, a city in the same prefecture, a plan that surfaced in 2022 to build a data center on a vacant lot south of the city hall had to be withdrawn due to opposition from residents.
The clashes between residents and the technology behemoths stem from a lack of suitable sites in Japan, considered an attractive location.
According to the Japan Data Center Council, Japan has better infrastructure and a stable political environment compared to other Asian countries, making it a prime location for large-scale technology investment.
However, proposed sites tend to be located around large cities where it is easy to access workers and telecommunications infrastructure is robust.
"The only suitable sites are in Tokyo, Osaka, and their suburbs," said JDCC executive director Naohiro Masunaga. With nearly all the options exhausted, businesses have no choice but to encroach into residential areas.
As demand for data handling explodes, facilities are becoming larger and larger. Hyperscale data centers -- facilities with a total floor space of more than 15,000 square meters -- have become common, with their integrated server farms meeting the processing needs of rapidly growing cloud computing, big data, and generative AI functions.
Fumito Haga, manager of Fuji Chimera Research Institute, said, "There is no doubt that the number of giant data centers will continue to increase."
Some municipalities are taking matters into their own hands. In April, Tokyo's Koto Ward started requiring data center business owners to install signs announcing construction earlier than previously and to clearly indicate the location of heat-emitting outdoor units.
Inzai has begun considering whether to set restrictions on the construction of data centers near residential areas.
JDCC's Masunaga said, "Right now, anxiety is prevailing. It is important for business owners to disclose information and steadily work to build trust with the communities affected."

Letter from Nikkei Asia's editor: Japan gripped by hot weather and heated politics
Hello from Tokyo. Just like last year, Japan is experiencing another brutally hot summer. I relocated from Nikkei's Singapore bureau to our Tokyo editorial headquarters in spring 2024, and it's clear that Tokyo is much hotter than the tropical island nation. As temperatures soar above 35 C, I find myself exhausted by the relentless daily commute through this concrete jungle. Japan's political climate is proving just as heated, and bringing with it a sense of deja vu. Following a major defeat in last weekend's upper house election, pressure is mounting on Prime Minister Shigeru Ishiba to step down. It was during a similarly sweltering August last year that then-Prime Minister Fumio Kishida announced his resignation over a political funding scandal. Ishiba has yet to make a similar announcement, but it now feels like only a matter of time. With the Liberal Democratic Party and its coalition partner Komeito losing their majority, the race to choose Japan's next leader promises to be marked by deep uncertainty. Meanwhile, Aug. 1 is the deadline for the U.S. Trump administration's tariff negotiations with various countries. Several Asian nations, including Japan, have reached agreements, while key ASEAN members remain in talks. On Thursday, the border clashes between Thailand and Cambodia escalated. Summer is usually a slow season for news, but this year seems to be an exception. Please log in to Nikkei Asia and stay up to date with the latest developments. My suggested reads 1. Sunday's upper house election in Japan marked a historic turning point, with the long-dominant Liberal Democratic Party falling into a minority position in both chambers of parliament for the first time since the party's formation in 1955. The main opposition Constitutional Democratic Party also struggled, while newer, upstart parties made significant gains. What's driving these dramatic shifts in Japan's political landscape? 2. Japan is confident that it has the technological chops to pioneer a new type of solar panel -- thin, light, flexible perovskite panels -- but perfecting the chemistry and scaling up production are only two of the challenges facing the country. As our story explains, it must also cultivate customers for new products in a market long dominated by Chinese manufacturers. 3. After eight tough years, driven by the arrival of ride-hailing apps and then the pandemic, Indonesia's best-known taxi operator, Bluebird, is enjoying a revival. Company President Director Adrianto Djokosoetono attributes the turnaround to focusing on consistently high service levels, diversification and not joining its rivals' price war. Our reporters take a closer look at the company's recent renaissance. Wishing you a wonderful weekend! Akito Tanaka Sign up for the weekly Editor-in-chief's picks newsletter here.
