Natsumikan is picked in summer from fruit that ripened the previous autumn — it is left hanging on the tree through the whole winter so the acid has time to fall, one of the longest deliberate on-tree holds of any commercial fruit.

Is natsumikan good for you?
Natsumikan is mostly water with natural sugars, a little fibre, and assorted micronutrients — a hydrating everyday addition to your overall fruit intake rather than a standout for any one nutrient.
How much natsumikan should you eat?
A typical fruit serving is roughly a handful, one medium fruit, or about 80 g, and two or more varied fruit servings a day is a sensible everyday pattern.
Why is natsumikan picked in summer?
Because it is inedibly sour when it looks ready. The fruit colours in autumn but its acid content stays far too high, so growers leave it hanging on the tree right through the winter and harvest from spring into summer, by which point the acid has fallen enough to eat. The name means summer mandarin, and it describes the harvest rather than the flowering. It is one of the longest deliberate on-tree holds in commercial fruit growing.
Why do people eat natsumikan with baking soda?
To cut the acidity. A pinch of sodium bicarbonate sprinkled on the peeled segments neutralises some of the acid and noticeably softens the sourness, and it is a traditional Japanese way of eating the fruit alongside the simpler option of sugar. The modern Kawano strain is sweeter than the original and needs it less.
What is the connection to samurai?
After the Meiji Restoration abolished the feudal stipend system in the 1870s, former samurai in Hagi, Yamaguchi Prefecture, were left without income. Natsumikan orchards were planted inside the old walled residential plots as a livelihood, and the fruit became the region's crop. Those walled orchards survive in Hagi as a preserved townscape, and the natsumikan blossom is Yamaguchi's prefectural flower.
