Sandisk and manufacturing partner Kioxia plan to invest more than $31 billion in Japan through 2032 to expand NAND flash memory production for artificial intelligence data centers. Announced in Tokyo on August 27, 2026, the six-year project is contingent on Japanese government support and builds upon a 25-year manufacturing alliance.
Flash memory specialist Sandisk and its long-term partner Kioxia announced a capital expenditure program in Tokyo. The initiative targets infrastructure expansion at their primary manufacturing hubs and aims to secure long-term component supply as the artificial intelligence boom drives demand for advanced storage chips.
Building a New Fab in Kitakami and Expanding Yokkaichi
The joint venture will channel the capital into dedicated infrastructure upgrades across two major production centers. According to reports from public broadcaster NHK, Kioxia plans to construct a third production facility at its plant in Kitakami, located in the northeastern prefecture of Iwate. Operations at this new fab are slated to begin in or after 2029.
Kioxia Chief Executive Officer Hiroo Ota stated that building the new Kitakami facility alone requires an investment of 1.8 trillion yen. The facility will manufacture the partners’ latest high-density 3D flash memory chips, designed specifically to handle massive data workflows generated by AI services. Alongside the Iwate expansion, the multi-billion-dollar program will support continued infrastructure buildout at the companies’ established manufacturing hub at the Yokkaichi Plant in Mie Prefecture.
Political Backing and Government Strategic Goals
The investment announcement followed a high-level meeting at the prime minister’s official residence in Tokyo. Kioxia Holdings CEO Hiroo Ota and Sandisk CEO David Goeckeler met with Japanese Prime Minister Sanae Takaichi to outline the multi-year strategy, confirming that the entire venture is contingent upon official government backing.
Prime Minister Takaichi emphasized the strategic importance of the sector, noting that semiconductors are a crucial strategic field for investment based on national growth strategy and economic security. Government plans envision a broader public-private investment exceeding 101 trillion yen—roughly $633 billion—dedicated to memory chips and advanced semiconductors for physical AI through fiscal 2040.
“This joint investment further strengthens our longstanding partnership with Sandisk and underscores Kioxia’s strong commitment to contributing to the advancement of an AI-driven society. Kioxia will continue to meet growing demand for high-capacity, high-performance, and power-efficient flash memory, which is essential to the growth of an AI-driven society. We sincerely appreciate the support of the Japanese government to date and recognize the importance of its continued strategic support in maintaining further strengthening our global competitiveness.”

Reconciling Massive Spending With Capital-Light Financial Strategy
A $31 billion commitment might appear to clash with recent corporate financial messaging. Just weeks before the Tokyo announcement, Sandisk management informed investors that the firm intended to expand supply primarily through technological upgrades rather than physical wafer additions, keeping capital expenditures low relative to revenue.
Financial analysis of the joint operating structure clarifies how the numbers align. The two companies manage production through Flash Ventures, a joint venture framework extended in January through December 2034. Sandisk holds a 49.9% stake in the operating entities, while Kioxia owns the underlying facilities. Sandisk is contractually obligated to fund between 49.9% and 50% of joint venture capital expenditures only when operating cash flow falls short, making Sandisk’s financial exposure a backstop rather than a blank check.
“For decades, Sandisk and Kioxia have jointly developed world-class NAND flash memory technology. In line with our business strategy and financial guidance, these planned investments will ensure our ability to support our customer’s increasing demands for our technology, while providing new economic opportunities for the communities we operate in and serving as a premier example of U.S.-Japan economic collaboration.”

Securing Demand Amid Industry-Wide Component Shortages
The aggressive expansion comes as global supply constraints raise component costs across the electronics and automotive sectors. Surging memory prices have begun to pinch profit margins for technology giants, with Nvidia executives issuing warnings regarding supply limitations during recent earnings briefings.
