Summary

Rapidus Corporation, a Japanese semiconductor startup founded in August 2022 and backed by major Japanese firms like Toyota, Sony, and NTT, is rapidly advancing towards 2nm mass production by 2027. This initiative is a national effort to establish a high-performance foundry for AI, autonomous driving, and edge computing, aiming to restore Japan's competitiveness in the global chip industry. Rapidus has already broken ground on its IIM-1 fab in Hokkaido in 2023, completed the cleanroom in late 2024, and successfully prototyped 2nm Gate-All-Around (GAA) transistors in July 2025, leveraging technology transferred from IBM. Furthermore, Rapidus unveiled "Raads" (Rapidus AI-Assisted Design Solution) in late 2025, which uses Large Language Models (LLMs) to aid engineers in designing chips for the 2nm process, with additional AI tools like Raads Navigator, Raads Manager, and Raads Optimizer planned for release throughout 2026.

Key takeaway

For investors and business analysts tracking the semiconductor industry, Rapidus represents a significant emerging player challenging TSMC's dominance, particularly in advanced 2nm logic chips for AI. Your investment decisions should consider Japan's strategic "all-or-nothing" bet on Rapidus, its rapid progress, and its innovative use of AI in manufacturing, which could reshape future supply chains and create new market opportunities by its targeted 2031 IPO.
