Unrolled roasted bancha
The hojicha route with the rolling taken out, and the omission is visible from across a room: the leaf never becomes leaf-shaped at all, and stays as whole flat brown blades that most people do not recognise as tea.
What makes this route what it is
The one route in the Japanese catalogue with no rolling stage. That single omission removes not one thing but four, in sequence: no rolling means no aracha worth refining, which means no fractions, which means no grades, which means the tea is sold as one thing and drunk as one thing. Everything the Japanese trade is organised around downstream of the drier simply does not apply, and the leaf's appearance is the visible proof of it.
The route, in order
Each note describes what the step is doing in this route. The same operation does a different job in a different chain.
Coarse mature leaf and stem taken late, frequently the material a district has left after its fine teas are made. The route asks nothing of the intake that would justify a hand pluck.
Some of this material arrives as a by-product of pruning rather than as a harvest in its own right, which is a different economic event and the same leaf.
Ordinary Japanese fixation, and the last point at which this route and the sencha route are doing the same thing. Coarse leaf takes a longer steam than a fine pluck, because there is more of it to heat through.

Drying
Straight to the drier, unrolled. The leaf dries flat and whole because nothing has twisted it, and it is at this step that the tea stops being able to become anything else — a leaf dried flat cannot be rolled afterwards.
The same operation a hojicha gets, applied to a leaf that has never been ruptured, and taken further. With almost nothing brought to the surface by rolling, the roast has to act on the leaf body itself, which is where the smoky, tarry register comes from rather than the caramel of a rolled hojicha.
Forced cooling immediately out of the roaster. Large flat leaf holds a surprising amount of heat and will carry on roasting itself in the heap, and this is the step that fixes where the roast actually stopped.
How it differs from its neighbours
A route described on its own teaches very little. The useful fact is always which other route it is nearly identical to, and where it leaves it.
This route leaves out an operation the other performs. Omissions are usually irreversible — the step cannot be added back later.
Same steamer, same roaster, and no roller in between. The hojicha route rolls, dries, refines and then roasts a selected fraction; this one dries what came out of the steamer and roasts all of it. The omission is why one product is a brown twisted leaf and the other is a brown flat one, and why the second cannot be graded — there is nothing to separate when nothing was cut to length.
The two routes are the same tea up to a point. Everything before the divergence is shared; everything after it is not.
Identical through the steamer, and then the sencha route spends four machines rolling while this one goes to the drier. Every commercial fact about Japanese tea downstream of that point — aracha as a saleable intermediate, refining, the four fractions, the firing houses — is a consequence of the rolling that happens here and does not happen there.
Where it goes wrong
The roast is the only lever and there is very little to hold it back — an unrolled, unruptured leaf with a large surface goes from woody to burnt without much warning in between, and there is no rolled-in density to buffer the heat. Under-roasted, the tea is thin and papery and tastes of nothing much, because the manufacture has removed every other source of character it might have had.
In full
Japanese green tea manufacture is normally an argument about how to roll. Four machines in sequence work the leaf while drying it, and the whole downstream trade — the refining tail, the fractions, the grades — exists because rolled leaf can be cut and sorted into things. This route does none of it. Coarse late leaf and stem, the material a Kyoto district has left after its gyokuro and sencha are made, is steamed and then taken straight to a drier, unrolled, and then roasted hard. What comes out is not a shape anybody designed: it is the leaf as it grew, flattened and browned, several centimetres across, and it looks like something swept up rather than manufactured. That appearance is the honest signature of the route, because a leaf that was never rolled has had almost none of its cells ruptured, and the roast is doing something quite different from what it does to a sencha. It is the only heat the leaf has ever really felt beyond the steamer, so it goes deep and produces a smoky, almost tarry aroma that the rolled hojichas do not reach. Everything a drinker notices about the tea follows from the missing step: it is very low in the compounds that rolling brings to the surface, so it is mild and low in caffeine, it will not over-brew, and it is boiled in a kettle rather than steeped in a pot because a whole unruptured leaf will not give anything up otherwise.
