When Does Premium Matcha Restock? (2026)

The Short Answer: It Depends on the Grade

There is no universal "restock day" for premium Uji matcha. Producers batch-process their stone-ground tencha as it becomes available from harvest inventory, and restocking timelines depend on stone-mill throughput, harvest volume, and international demand. What is consistent is this: the higher the grade, the faster it sells out, and the less predictable the restock timing.

The patterns below are drawn from observed restock behaviour during 2025–2026. They are typical, not guaranteed — shortage conditions and seasonal harvest timing can shift any of these timelines significantly.

Why Restock Timing Is Unpredictable

Premium Uji matcha producers do not publish restock schedules. There are several reasons:

• Harvest-dependent supply: The first spring harvest (ichibancha) sets the entire year's inventory. Once the tencha from a harvest is ground and sold, there is no more until the following year. Restock timing depends entirely on how quickly inventory is processed through stone mills.
• Stone-mill throughput is fixed: Granite mills grinding at 40 grams per hour cannot be sped up. A large order from a tea ceremony school can delay availability for other buyers by days or weeks.
• Demand spikes are unpredictable: A viral social media post, a press mention, or a holiday gifting season can exhaust months of stock in days. These events are not foreseeable in advance.
• International shipping delays: Even when a product is "in stock" at the Japan store, international shipping adds time. Some customers see restocks that international buyers cannot access quickly enough to order before stock depletes again.

The Seasonal Calendar: When Is Matcha Most Available?

April–June: New Harvest Season

The first spring flush (ichibancha) is harvested in April–May. New batch releases from the current harvest appear in shops from late April through June. This is the period of greatest availability — set your alerts in March to be ready when first-harvest restocks begin.

July–September: Post-Harvest Restocks

Producers process and release batches as stone-mill capacity allows. Restocks are irregular but occur every few weeks for popular grades. This is still a good window — the new harvest's tencha is fresh and hasn't been depleted yet.

October–January: Deepening Scarcity

As the harvest year progresses, upper-tier inventory depletes and restocks become less frequent. The pre-holiday gift period (November–December) also creates demand spikes. This is the period when stock alerts matter most — availability windows shrink.

February–March: Pre-Harvest Gap

The toughest period. Last year's harvest inventory is nearly depleted; the new harvest has not yet been processed. Upper-tier grades may disappear entirely for weeks at a time. During the 2025–2026 shortage, some grades were unavailable for 3+ months during this window.

What To Do Right Now

1. Identify every grade you want across all brands — not just your first choice. If Ippodo Ummon is unavailable, Marukyu Wako or Nakamura Tokichi Sho no Mukashi might be.
2. Set up stock alerts for all of them simultaneously. There is no cost to monitoring multiple grades at once, and it dramatically increases your chances of securing at least one premium tin per purchase cycle.
3. Pre-create accounts at Ippodo Japan, Ippodo US, and Marukyu Koyamaen official stores. Saved payment and shipping details are the difference between completing a purchase in 45 seconds vs. 5 minutes — and 5 minutes can mean a sold-out page.
4. When an alert fires, act within 30 minutes for upper-tier grades. Treat it as urgent. Finish what you are doing and complete the checkout.
5. Buy at least two tins when purchase limits allow. Unopened tins stored in the refrigerator maintain quality for months. Running out and waiting for the next restock is more disruptive than having a tin in reserve.
