Two data-centre stories from 6–7 October 2026 show both sides of the AI infrastructure boom. In Japan, Blackstone-backed AirTrunk is putting an extra $1 billion into a large campus to make it ready for AI workloads, financed with a green loan [1]. In Finland, the state licensing regulator has told Google’s local subsidiary to stop groundwork at two planned data-centre sites until environmental impact assessments are finished [2][3].
Both developments are confirmed: AirTrunk’s by the company, as reported by Reuters, and Finland’s by the regulator’s own notice and Google’s response to CNBC [1][2][3]. Together they show that capital for data centres is plentiful; suitable places to build them, quickly and with public consent, are not.
AirTrunk: what was announced?
AirTrunk said on 7 October that it is investing an additional $1 billion in its hyperscale data-centre campus in Inzai, in eastern Japan, which has more than 300 megawatts of capacity, to enable AI workloads [1]. The campus is known as TOK1.
According to Reuters [1]:
- The investment is for deploying liquid-cooling technology to support AI workloads.
- AirTrunk has secured a $1 billion green loan led by Sumitomo Mitsui Banking Corp, MUFG Bank and United Overseas Bank, among others.
- Chief executive Robin Khuda says TOK1 is likely to be the first campus in Japan to host large-scale AI workload deployment.
Why liquid cooling?
AI chips run much hotter than the servers most data centres were designed for. Packing many of them together produces more heat than air cooling can easily remove, so operators are piping liquid closer to the hardware. Reuters’ summary ties AirTrunk’s spending directly to that upgrade [1]. In plain terms, the $1 billion is mostly about making an existing large site able to host the newest, densest AI hardware, rather than about adding a new building from scratch.
Why Japan, according to AirTrunk?
Khuda gave two reasons, both reported by Reuters [1].
First, geopolitics: “Due to geopolitical reasons, we are seeing more and more customers looking to Japan from a North Asian perspective.”
Second, the difficulty of building elsewhere. Khuda says deploying AI infrastructure will get harder in the United States, is already hard in Europe, and that this makes Asia a “big beneficiary” [1].
That is the view of a company selling capacity in Asia, so it is not neutral. But the second story this week gives it some support.
Finland: what did the regulator do?
On 6 October 2026, Finland’s Licensing and Supervision Agency (Lupa- ja valvontavirasto, LVV) issued Google subsidiary Tuike Finland Oy with a formal instruction to suspend preparatory work at two planned data-centre projects, in Muhos and in Kajaani, until their environmental impact assessments (EIAs) are completed [2][3].
According to the LVV’s own notice [2]:
- The suspension must happen immediately, and no later than 23 October 2026.
- It covers preparatory work that significantly changes the environment, including tree removal, topsoil stripping, excavation, quarrying, crushing, moving soil, ditching, and building site roads and storage areas.
- It does not cover planning, measurements, soil surveys or other minor work that can easily be reversed.
- The instruction is based on section 32(2) of Finland’s EIA Act.
- Tuike Finland has until 14 October to give a written explanation, and is specifically asked to say whether it intends to comply.
Headlines have described this as an order. Strictly, the LVV notice is a formal instruction with a right to respond. But it has teeth: if Tuike Finland does not comply, the LVV says it will consider administrative enforcement under the EIA Act or other relevant law, which can be reinforced with a conditional fine [2]. The agency says its first aim is for the company to fix the situation voluntarily [2].
Why did the regulator step in?
The LVV says that, based on the information it has received, large-scale preparatory work has already been carried out at the sites, including tree removal, topsoil stripping, building site roads and storage areas, changes to ditches and culverts, and stormwater works [2]. It had requested that information on 18 September from Tuike Finland and from the Muhos and Kajaani local authorities [2].
Tommi Muilu, head of the LVV’s environmental department, said those measures “will change the environment and cause impacts, the identification and assessment of which are among the key objectives of the EIA procedure” (CNBC’s translation) [3]. In the agency’s notice he adds, in our translation, that large-scale preparatory work can weaken the EIA’s role in guiding a project before decisions are made, and narrow the chance to consider alternatives and prevent harmful effects [2].
Put simply: the point of an environmental assessment is to happen before the bulldozers. The regulator thinks too much happened first.
The LVV says both EIAs are still in progress, and that the assessment reports are expected to be completed during 2026 [2].
What did Google say?
Google accepted the criticism. A spokesperson told CNBC: “We understand the concerns and have fallen short of our own high standards in this instance,” adding that the company would follow the LVV’s guidance [3].
The spokesperson also said: “We acted in good faith under the Forestry Act, and ran nature surveys and put in place measures to protect high-value areas,” and that Google is advancing landscaping and biodiversity plans, including tree planting across 130 hectares at Muhos [3].
How big is Google’s Finland plan?
Large. CNBC reports the halt comes a month after Google committed to investing $15 billion in AI infrastructure in Finland, which Google says will be its largest investment in Europe, deployed through 2028 into data centres and supporting investments such as energy projects [3].
CNBC also notes Finland’s appeal for the industry: available land and power, both in short supply across most of Europe, have led to the country being dubbed the “Texas of Europe” [3].
What links these two stories?
Money is not the constraint in either case. AirTrunk raised a $1 billion green loan from major banks [1]. Google has pledged $15 billion for Finland [3].
The constraints are physical and political: power, cooling, land, and the permission to change a landscape. Japan is drawing customers partly, in AirTrunk’s telling, because building elsewhere is getting harder [1]. Finland, one of Europe’s most attractive sites, has just shown what “harder” can look like: a regulator insisting that environmental review comes before site clearance [2].
The Finnish case does not cancel Google’s projects. It puts the order of operations back in place. But for anyone tracking AI CapEx, it is a reminder that announced investment and dug foundations are not the same thing, and that the gap between them is set by local rules.
What this does not prove
- That Google’s Finnish projects are cancelled or delayed by a set amount. The suspension lasts until the EIAs finish, which the LVV expects during 2026; no new completion date for the data centres has been given [2][3].
- That Google will be fined. Enforcement and a conditional fine are possible only if Tuike Finland does not comply; Google says it will follow the guidance [2][3].
- That TOK1 will in fact be Japan’s first large-scale AI campus. That is the CEO’s expectation, as reported by Reuters [1].
- That building in Europe or the US is now impractical. Khuda’s comments are one operator’s view, and his company benefits from demand shifting to Asia [1].
- Who AirTrunk’s AI customers at TOK1 are. The report does not name them [1].
The Bottom Line
AirTrunk is spending an extra $1 billion, backed by a $1 billion green loan, to fit its 300MW-plus TOK1 campus in Japan for liquid-cooled AI workloads [1]. Finland’s licensing regulator has told Google’s subsidiary to halt environment-changing groundwork at Muhos and Kajaani by 23 October until environmental reviews are complete, and Google has said it fell short of its own standards [2][3].
The capital for AI data centres is clearly there. The harder question is where they can be built, how fast, and on whose terms. This week’s answer: faster in some places than others, and only after the paperwork in places that insist on it. None of this is investment advice.
