日本無線基礎設施（2026）：無線接取網路市場分析與預測 | 4G、5G、6G 基地台、開放式無線接取網路、虛擬無線接取網

日本是全球最具戰略意義和技術最先進的無線接取網路（RAN）市場之一，也是最具特色的市場之一。它是唯一一個100%採用開放式RAN（Open RAN）並積極推進開放式虛擬化RAN（vRAN）的主要市場。對於全球專注於RAN架構未來的通訊業者、供應商和投資者而言，日本不僅是一個值得關注的市場，更是一個可供參考的藍圖。

本報告對日本無線接取網路(RAN) 市場進行了深入分析，提供了 2016 年至 2025 年的歷史市場數據，包括年度市場規模和供應商市場佔有率，以及到 2031 年的詳細預測，涵蓋了所有世代的 4G LTE (eNodeB)、5G 新空口 (gNodeB) 和 6G 無線接入基礎設施。

Japan RAN Market Report 2026: 4G, 5G & 6G Base Station Analysis & Forecast Through 2031

The Only Japan RAN Report Built on Operator Data, Vendor Confidential Sales & 20 Years of Network Rollout Analysis

Japan is one of the world's most strategically important and technically advanced RAN markets - and one of the most unique. It is the only major market where RAN is 100% open RAN, and it is actively migrating to open virtualized RAN (vRAN). For operators, vendors, and investors tracking the future of RAN architecture globally, Japan is not just a market to monitor - it is a blueprint.

This report delivers the most granular, data-rich analysis of Japan's RAN market available anywhere, combining government statistics, operator reporting, and confidential vendor sales data into a single authoritative source.

In This Report:

This report analyzes Japan's Radio Access Network market across all active and emerging generations: 4G LTE (eNodeBs), 5G New Radio (gNodeBs), and 6G radio access infrastructure. It presents historical market data from 2016 to 2025, annual market sizing and vendor market shares, and a detailed forecast through 2031 - broken down by RAN units and revenue for each network generation.

What Makes This Report Different

Most Japan RAN reports rely on publicly available data alone. This one goes further. The historical dataset is built from a combination of:

• - Japan Ministry of Internal Affairs and Communications (MIC) statistics - the authoritative source on Japan's telecommunications infrastructure
• - Mobile network operator reporting and direct discussions - capturing deployment intent and rollout plans straight from the source
• - Sales data from a dozen active RAN vendors in Japan - including confidential sales figures shared exclusively with TÉRAL RESEARCH

The result is a level of data accuracy and vendor-level granularity that no public dataset can match.

The market forecast is equally rigorous - built on a model that correlates RAN equipment vendor sales with 20 years of service provider network rollout patterns, upgrades, and expansion plans. This is not extrapolation. It is a structurally grounded forecast.

What You Get:

• Historical market data from 2016 to 2025
• Annual market sizing in units and revenue for 4G, 5G & 6G RAN
• Vendor market shares across all active RAN suppliers in Japan
• Detailed market forecast through 2031 by network generation
• Analysis of Japan's 100% open RAN environment and vRAN migration trajectory
• Forecast model grounded in 20 years of Japanese operator network rollout analysis
• Coverage of the full vendor ecosystem active in Japan, including vendors that shared confidential sales data exclusively with TÉRAL RESEARCH
