Translation

In early autumn, a sweet scent spreads through the streets.

It is the sign that the kinmokusei flowers have all opened at once.

The flowers are tiny grains about five millimetres across, blooming in clusters along the branches.

The scent is said to travel on the wind as far as a hundred metres.

The bloom lasts only about a week, and rain brings the flowers down.

It is a tree that tells you autumn has come through your nose before your eyes.

When does kinmokusei bloom in Japan?

Every year, somewhere between late September and October, people all over Japan look up from the pavement and say the same thing: it smells like autumn. The source is kinmokusei, the fragrant orange-olive (Osmanthus fragrans var. aurantiacus), a modest evergreen tree planted in gardens, school yards and along ordinary residential streets.

The flowers themselves are almost nothing to look at. Each one is a cluster of orange grains only about five millimetres across, tucked along the branches under dark green leaves. The scent is the opposite: sweet, apricot-like and strong enough to travel on the wind well beyond the garden it came from. In Japan, kinmokusei is grouped with spring's jinchoge (winter daphne) and summer's kuchinashi (gardenia) as one of the sandai koboku — the three great fragrant trees.

There is a quirk almost no one notices. Nearly every kinmokusei in Japan is a male tree. The species came from China, and because it has been propagated by cuttings ever since, the trees are effectively clones of male stock, so they almost never bear fruit.

The bloom is also brief. A tree is usually at its peak for only about a week, and one night of rain can bring the flowers down and leave an orange carpet on the ground. In some years a tree blooms a second time within the same autumn.

This article comes in six versions by school grade, each with furigana and a full translation, so you can read it at whatever kanji level you are at today.

Why do kinmokusei trees in Japan almost never produce fruit?

Because almost all of them are male. The species was brought from China and has been propagated by cuttings ever since, so the trees growing in Japan are essentially clones of male stock. With virtually no female trees to pollinate, fruit is almost never seen.

Why six school grades, and not N5–N1?

Because that is how Japanese children learn to read. Japan's Ministry of Education fixes exactly which character belongs to which grade — so "grade 3" is a boundary you can verify, not a feeling. Every article here is machine-checked: if a single character sits above its grade, it is not published.

The result: you never hit a character you have not learned. That is the whole reason this product exists.
