**Rakuten Mobile Delivers Blazing 423Mbps Speed in Osaka’s Crowded Hotspots**
*株式会社ALL CONNECT*

**Introduction**
Rakuten Mobile has turned heads in Japan’s telecom scene after recording a peak download speed of 423 Mbps in several of Osaka’s busiest districts. The measurement, taken during rush‑hour periods in Namba, Umeda and Shinsaibashi, shows the carrier’s ability to maintain high‑performance connectivity even when thousands of users compete for bandwidth. The result underscores Rakuten’s aggressive network‑expansion strategy and signals a shift in how urban users experience mobile data.

**Key Developments**
Independent speed‑test firms conducted the measurements using standardized LTE‑Advanced and 5G NR protocols. In Namba’s shopping arcade, the average downstream rate hovered around 310 Mbps, with spikes reaching the 423 Mbps mark during brief lulls in foot traffic. Similar figures emerged in Umeda’s underground mall and Shinsaibashi’s covered walkway, environments traditionally plagued by congestion due to dense retail and transit hubs. Rakuten attributed the performance to its newly deployed massive‑MIMO arrays, carrier‑aggregation across 2 GHz and 3.5 GHz bands, and dynamic spectrum sharing that reallocates LTE resources to 5G demand in real time.

**Industry Analysis**
The achievement places Rakuten Mobile ahead of many legacy operators in real‑world urban throughput, a metric that increasingly influences consumer choice and enterprise SLAs. Analysts note that while peak laboratory speeds often exceed 1 Gbps, sustaining >400 Mbps in crowded settings remains a differentiator. The result also pressures competitors to accelerate their own densification plans, particularly in Kansai where
