日本資料中心建置市場趨勢與洞察

加速雲端運算、人工智慧和巨量資料工作負載

生成式人工智慧專案的激增導致機架密度超過100kW，電力需求成長高達20%，迫使營運商採用液冷系統。軟銀位於苫小牧的300MW園區樹立了規模新標桿，並爭取100%可再生能源供電。櫻花網際網路等GPU雲端服務供應商預計到2025年獲利將成長476.3%，印證了強勁的需求驅動力。日本大型石油公司出光興產目前正在供應可將冷卻能耗降低90%的浸沒式冷卻液，從而建造了一條永續人工智慧基礎設施的區域價值鏈。

美國及國內主要雲端運算公司正在擴張超大規模園區。

AWS已累計2.26兆日圓用於2027年的項目，預計每年將創造30,500個就業崗位，並對GDP產生5.57兆日圓的影響。 Oracle的80億美元計畫則專注於滿足客戶在東京和大阪的資料主權需求。在日本國內，KDDI和夏普正計劃透過合作打造亞洲最大的雲端園區之一，而EdgeConnex則在大阪部署140兆瓦的設備，用於建構人工智慧叢集。這些多年期項目正在推動建築訂單的成長，並加劇對技術承包商的競爭。

電網瓶頸和電費飆漲

關西電力公司計劃投資超過1,500億日圓建造四座變電站，從2026年開始為新建校區供電。電力公司正面臨併網等待時間過長以及電價差異的問題，北海道電價最高，北陸電價最低。成本上漲擠壓了利潤空間，而水冷技術的引進也導致電力消耗量歷史新高。一些公司正在簽訂可再生能源購電協議（PPA）或建造自有發電設施，以規避風險。

細分市場分析

預計到2025年，電力基礎設施將佔銷售額的37.62%，透過高壓開關設備和母線槽的升級改造，奠定日本資料中心建設市場佔有率的基礎。儘管服務業規模較小，但預計到2032年將實現8.05%的複合年成長率，因為營運商需要為抗震設計、液冷設計以及人工智慧工作負載的佈局最佳化支付額外費用。佳能IT解決方案公司位於東京西部的資料中心目前支援100kVA液冷機架，展示了混合冷卻技術的整合應用。自2021年以來，建築材料價格上漲了21%至24%，企業正轉向模組化施工和預製電力機房，以縮短交貨時間。

日本資料中心建置市場服務領域的擴張反映了由生成式人工智慧普及所驅動的對容量規劃、試運行和維修諮詢服務日益成長的需求。儘管機械基礎設施正朝著介電液體和晶片直接冷卻的方向發展，但IT基礎設施依然穩健，儘管企業不斷向雲端遷移，GPU伺服器的訂單依然強勁。

到2025年，Tier III級資料中心將佔據日本資料中心建置市場56.42%的佔有率，主要針對注重成本的企業和託​​管用戶。雖然Tier IV級資料中心計畫數量較少，但預計到2032年將以8.43%的複合年成長率成長，因為超大規模業者需要更高的資本投入以確保人工智慧模型訓練的不間斷運作。大林組株式會社採用主動式隔震結構及超高強度鋼材，以確保地震多發地區Tier IV級資料中心的運作。

日本的Tier IV資料中心建設市場主要集中在東京-大阪走廊，該地區高昂的土地成本使得高密度、高可用性的設計方案成為可能。同時，隨著租戶將工作負載遷移到對容錯能力要求更高的雲端平台，Tier I和Tier II傳統資料中心的使用率正在下降。

第7章 市場機會與未來展望

According to Mordor Intelligence, the Japan data center construction market size is expected to grow from USD 7.14 billion in 2025 to USD 7.59 billion in 2026 and is forecast to reach USD 10.91 billion by 2032 at 6.24% CAGR over 2026-2032.

This report is Segmented by Infrastructure (Electrical Infrastructure, Mechanical Infrastructure, and More), Tier Standard (Tier I and II, Tier III, and More), Data Center Type (Colocation, Hyperscale, and More), End User Industry (Banking Financial Services and Insurance, IT and Telecommunications, and More). The Market Forecasts are Provided in Terms of Value (USD).

Japan Data Center Construction Market Trends and Insights

Accelerating Cloud, AI and Big-Data Workloads

Rising generative-AI projects lift rack densities to 100 kW plus, raising electricity demand by up to 20% and forcing operators toward liquid immersion systems. SoftBank's 300 MW Tomakomai campus shows the new scale benchmark and targets 100% renewable power. GPU cloud providers such as Sakura Internet recorded a 476.3% profit jump in 2025, underscoring demand pull. Domestic oil major Idemitsu now supplies immersion fluids that cut cooling power 90%, anchoring a local value chain for sustainable AI infrastructure.

Hyperscale Campus Build-Outs by US and Domestic Majors

AWS has budgeted JPY 2.26 trillion through 2027, adding 30,500 annual jobs and JPY 5.57 trillion GDP impact. Oracle's USD 8 billion plan centers on data sovereignty clients in Tokyo and Osaka. On the domestic front, the KDDI-Sharp alliance aims to open Asia's largest cloud campus, while EdgeConneX is deploying 140 MW in Osaka to serve AI clusters. These multiyear programs anchor construction order books and intensify competition for skilled contractors.

Grid-Power Bottlenecks and Surging Electricity Tariffs

Kansai Electric will invest more than JPY 150 billion from 2026 on four substations serving new campuses. Operators face extended grid-connection queues and tariff spreads that make Hokkaido the most expensive and Hokuriku the least. Higher costs strain profit margins just as liquid cooling drives power draw above historic norms. Some firms lock renewable PPAs or install on-site generation to hedge exposure.

Other drivers and restraints analyzed in the detailed report include:

1. Sovereign-Cloud and Data-Residency Regulations
2. 5G-Driven Edge-DC Demand in Secondary Metros
3. Scarcity of Tier-III/IV-Certified MEP Labor

Segment Analysis

Electrical infrastructure accounted for 37.62% of 2025 revenue, anchoring the Japan data center construction market share with high-voltage switchgear and busway upgrades. Services, though smaller, are forecast to achieve an 8.05% CAGR through 2032 as operators pay premiums for seismic engineering, immersion-cooling design, and AI workload layout optimization. Canon IT Solutions' West Tokyo site now supports 100 kVA liquid-cooled racks, showcasing hybrid cooling integration. Construction material inflation of 21-24% since 2021 pushes firms to modularize builds and pre-fabricate power rooms for faster delivery.

Japan data center construction market size expansion in services reflects demand for capacity-planning, commissioning, and retrofit consulting tied to generative-AI ramps. Mechanical infrastructure evolves toward dielectric fluids and direct-chip cooling, while IT infrastructure maintains steady orders for GPU servers despite enterprise cloud migration.

Tier III facilities maintained 56.42% Japan data center construction market share in 2025, serving enterprises and colocation tenants that value cost balance. Tier IV projects, though fewer, are rising at 8.43% CAGR through 2032 as hyperscale operators accept higher capital intensity for uninterrupted AI model training. Obayashi deploys active base isolation and ultra-high strength steel to secure Tier IV uptime in seismic zones.

Japan data center construction market size for Tier IV builds concentrates in the Tokyo-Osaka corridor where land costs justify high-density, high-availability designs. Tier I and Tier II legacy sites see attrition as tenants migrate workloads to cloud platforms demanding higher fault tolerance.
