Akihabara Retailers Implement Strict Purchase Limits as Prices More Than Double

TOKYO, November 8, 2025 — Major computer component retailers in Tokyo’s Akihabara district have implemented unprecedented purchase restrictions on memory and storage products as a global supply shortage driven by artificial intelligence infrastructure demand reaches crisis levels, with some DDR5 memory modules experiencing price increases exceeding 100%.

Severe Purchase Restrictions Take Effect

Since early November, prominent DIY computer shops including PC Shop Ark, Tsukumo PC Main Store II, and TSUKUMO eX have imposed strict purchase limits on RAM, SSDs, and HDDs. PC Shop Ark has limited customers to just eight items per group, while TSUKUMO stores have implemented even more stringent restrictions, allowing only two storage drives or SO-DIMMs and up to four memory modules per buyer, with negotiated exceptions only for complete PC or NAS system purchases.

Store representatives have cited “severely limited inventory” as the reason for the restrictions, with no timeline established for lifting the purchasing caps. Some products have already been discontinued by distributors, and retailers who haven’t yet implemented limits are expected to follow suit as inventory constraints intensify.

The AI Connection: A Perfect Storm

The root cause of the shortage traces directly to the insatiable demands of artificial intelligence infrastructure. AI data centers have begun consuming the lion’s share of the world’s memory and flash production capacity, with every GPU node in a training cluster potentially consuming hundreds of gigabytes of DRAM and multiple terabytes of flash storage.

South Korean memory manufacturer SK Hynix announced that its supply of high-bandwidth memory (HBM) chips was sold out for 2024 and most of 2025, with competitor Micron issuing a similar statement in March. This specialized memory, essential for AI processing, has created a cascade effect throughout the entire memory supply chain.

Production Reallocation Squeezes Consumer Supply

Memory manufacturers like Samsung and SK Hynix are redirecting factory capacity from standard server RAM to high-demand components like HBM needed for AI chips, causing major cloud providers in the United States and China to receive only about 70% of their DRAM orders.

Micron has presold almost all of its High Bandwidth Memory (HBM) output through 2026, with contracts that once covered a quarter now spanning years as hyperscalers buy directly at the source. This strategic reallocation has left conventional memory markets severely undersupplied.

Price Surge Across All Memory Types

The impact on pricing has been dramatic and widespread:

DDR5 Memory: Some models have experienced 100% price increases, with extreme supply instability
Server DRAM: Contract rates for Registered DIMMs (RDIMMs) have jumped by up to 50% for the fourth quarter of 2025
Consumer DRAM: Memory costs roughly 120% more than a year ago, forcing even budget computing platforms like Raspberry Pi to raise prices
SSDs and HDDs: Western Digital confirmed supply shortages for both HDD and SSD in April, with HDD pricing increasing by 5-10%

Market Dynamics Favor Manufacturers

The HBM sector’s revenue is anticipated to climb from $14 billion in 2024 to $38 billion in 2029, after soaring by more than 150% year-over-year from around $5.5 billion in 2023. This profitability differential creates strong economic incentives for manufacturers to prioritize AI-focused production over consumer products.

Some memory suppliers in China have begun abandoning traditional long-term contracts in favor of a dynamic “daily pricing” model to avoid getting locked into unfavorable deals as costs escalate.

Long-Term Outlook Remains Uncertain

Industry experts warn that the shortage could persist far longer than previous supply chain disruptions. Phison CEO has claimed that NAND shortage could last a staggering 10 years, though other analysts offer more moderate predictions.

The situation differs from past component shortages caused by natural disasters, the COVID-19 pandemic, or currency fluctuations. Hyperscaler capital expenditures on data centers and related items have risen fourfold and are nearing $400 billion annually, representing a fundamental structural shift in memory demand rather than a temporary disruption.

Impact on Consumers and PC Builders

For consumers considering building or upgrading gaming PCs, the timing is particularly unfavorable. The era of affordable SSDs and memory that characterized 2023—when high-performance NVMe drives sold for prices comparable to mechanical hard drives—has definitively ended.

Japanese retailers have expressed concerns that the situation could worsen before improving, noting that “due to AI-related product demand increases, component supply has entered a period of tension.” Past experience suggests that price stabilization typically requires considerable time, potentially extending well into 2026 or beyond.

Manufacturing Capacity Expansion Underway

Major memory manufacturers are responding with capacity expansions, though these will take time to materialize. Samsung’s P4L plant is slated for completion in 2025, SK Hynix’s M16 expansion will happen in 2025, and Micron’s Boise facility is expected to be completed in 2025 with mass production planned for 2026.

However, these expansions are primarily targeted at HBM and advanced AI memory production rather than consumer products, suggesting that relief for the consumer market may be limited even as overall capacity increases.

Conclusion

The memory shortage affecting Japan’s Akihabara district represents a microcosm of a global supply chain crisis driven by the artificial intelligence revolution.

As AI infrastructure continues its exponential growth trajectory, consumer electronics markets face an extended period of constrained supply and elevated pricing—a new reality that challenges the long-held expectation of ever-declining technology costs.
