Japanese Matcha Harvest Seasons Explained: Ichibancha, Three Regions, and the 2026 Vintage
Share
Japan picks tea in four flushes a year. Ichibancha (first harvest, late April to May) makes ceremonial matcha. Nibancha (late June to early July) and sanbancha (late July to August) fill premium and culinary grades. An autumn cut, shūtō bancha, goes into bancha and hojicha.
- Regional timing varies: Yame and Kagoshima in the south pick earliest, Uji in the cooler north usually last.
- 2026 was a strong vintage in Uji, but the ongoing shortage means prices stayed high anyway.
- A field takes 4 to 5 years before it can support commercial matcha production.
Every tin of matcha starts as a specific pick, on a specific field, in a specific week of the Japanese growing calendar. Get that week right and the leaf carries sweetness and depth. Miss it, in either direction, and the same field produces something coarser and more bitter.
We buy directly from farms in three regions, Uji, Yame, and Shizuoka, and the harvest calendar looks different in each. Here's how the seasons actually work, what changed in 2026, and how to read a harvest claim on a label without getting talked into paying ceremonial prices for third-flush leaf.
Japan names its tea harvests by order in the year, and the names track real differences in chemistry and use, not just the calendar.
| Harvest | Window | Character | Typical use |
|---|---|---|---|
| Ichibancha (first) | Late April – May | Sweet, high umami, minimal bitterness | Ceremonial and premium ceremonial matcha |
| Nibancha (second) | Late June – early July | Brighter, more astringent | Everyday ceremonial, blends |
| Sanbancha (third) | Late July – August | Coarser, noticeably more bitter | Culinary matcha, baking |
| Shūtō bancha (autumn) | Late Sept – October | Milder, lower caffeine | Bancha, hojicha |
You'll also hear shincha (新茶), meaning "new tea." It's the same leaf as ichibancha, marketed for the moment it first reaches drinkers each spring. Tradition ties it to the 88th night after risshun, the old lunar marker for the start of spring, which lands in early May. The label changes; the leaf underneath it doesn't.
Harvest calendars aren't uniform across Japan. Latitude, elevation, and local climate shift the picking window by one to three weeks between our three sourcing regions, and that timing difference shows up in the cup.
A "first harvest" claim from Yame and a "first harvest" claim from Uji can sit two or three weeks apart on the calendar and still both be genuinely ichibancha. Region explains a good chunk of the flavour difference between our matcha lines, even at the same harvest tier.
Over autumn and winter, the tea plant banks nutrients in its roots and woody growth. When spring buds break, those reserves flow straight into the new leaves, concentrated in a small amount of tender growth rather than spread across a full season's foliage.
That concentration shows up as amino acids, chiefly L-theanine, running high and bitter catechins running low. Every flush after that inverts the ratio a little further: more sun exposure, more catechin production, less theanine to soften it. By third flush, the leaf is coarser in texture too. Top-grade first-flush leaf is thin and tender enough that it's nearly edible on its own.
Picking date inside first flush matters as well. Wait too long and amino acids start dropping while the leaf toughens. Pick too early and yield collapses before the plant has built up enough reserve. Farmers judge this by feel, by cultivar, and by how the season has run, not by a fixed date on a calendar.
We were in Uji for the 2026 first flush, and by most measures it was one of the best harvests in nearly three decades. Well-timed spring rainfall produced deeper chlorophyll, more concentrated L-theanine, and a finer mill than the region has seen in years.
A strong harvest and a shortage can happen at the same time, and 2026 is proof. Quality went up. Prices did not come down. The ongoing 2026 matcha shortage means tencha auction prices are still running roughly 1.7 times where they sat before the shortage began, regardless of how good any single season's leaf turns out to be. A great vintage doesn't undo years of demand outpacing what a five-year field-maturation cycle can supply.
Matcha doesn't start as ordinary open-field leaf. Fields destined for tencha, the leaf that becomes matcha, are shaded for roughly three to four weeks before picking, sometimes longer for the top lots.
Blocking sunlight pushes the plant to build more chlorophyll and hold onto amino acids instead of converting them into catechins under sun stress. That shade-driven aroma has its own name in Japanese, ooika. Three shading methods are in common use, from simplest to most labour-intensive: jikakabuse (cloth draped directly over the bushes), kanreisha (synthetic cloth on an overhead frame), and honzu (traditional reed and straw screens on a raised structure, rarer and far more expensive to maintain).
Bush shape varies too. Most fields are trimmed into hedgerows for machine harvesting. Some of the most prized lots are grown as individual, free-form bushes and hand-picked once a year, a slower and costlier method that puts less mechanical stress on the plant.
Harvest is the start of the process, not the end. What happens in the days and weeks after picking determines whether that first-flush promise actually reaches your cup.
Not every kilo that comes off a first-flush field ends up as ceremonial matcha. Sorting is strict: leaf with too much stem, uneven colour, or a coarser texture gets pulled and graded down rather than discarded. It's the same field, the same season, just a different tier of the same harvest.
That graded-out material doesn't go to waste. Later flushes and lower grades from the very same farms typically become premium or culinary matcha, and mature bancha and kukicha leaf, picked later in the season specifically for this purpose, gets roasted into hojicha. If you've read our piece on what hojicha actually is, this is the other half of that story: hojicha isn't an afterthought tea, it's what a well-run farm does with the leaf that doesn't suit matcha.
Camellia sinensis is a perennial evergreen, not an annual crop. A well-managed bush stays productive for decades, commonly cited in the 50 to 100-plus year range, and some of Japan's most prized gardens are over a century old.
Getting that lifespan depends on restraint as much as care: winter rest after autumn pruning, selective harvesting rather than stripping every flush, and shading only once the plant is strong enough to carry it. Push a field through three or four heavy harvests with no recovery and the plant's stored reserves run down. You get more leaf this year and a noticeably weaker flush next spring. Serious matcha farming treats the bush as an asset to protect across decades, not a crop to maximise this season.
Japan grows matcha cultivars from cuttings, not seed, and a new field takes years to earn its keep.
| Age | What's happening |
|---|---|
| Year 0 | Cuttings planted |
| Years 1–2 | Root establishment, little to no harvest |
| Years 3–4 | Light harvesting begins, quality still developing |
| Years 4–5 | Commercial matcha harvest becomes viable |
| Years 8–10+ | Yields and quality stabilise |
| 20–50+ years | Deep root systems, greater complexity; many premium gardens are this age or older |
That timeline is the real ceiling on the 2026 shortage. Planting more fields this year doesn't produce more ceremonial matcha this year, or even next year. It produces more matcha in four to five years, at the earliest, which is exactly why the shortage has stretched on rather than resolving in a single season.
Harvest tier is one of the clearest, least gamed signals you have as a buyer. Match it to what you're actually doing with the matcha.
If a listing says "ceremonial grade" with no harvest, no region, and no cultivar, you have no way to check any of the claims in this article against the actual leaf. That absence of detail is itself information.
Maison Koko buys directly from farms we know by name across Uji, Yame, and Shizuoka, rather than through brokers blending unnamed leaf. That's the difference this article is really about.
