Japan is known for its rich culture, picturesque landscapes, and mouthwatering gourmet delights. Beyond ramen and sake, the country is also home to a treasure trove of fruits that are celebrated for their intense flavours. Blessed by Japan’s geography and refined by the expertise of local cultivators, these fruits are a must-try for anyone hunting for regional specialties.
Many of these fruits are highly seasonal, appearing only at specific times of the year, which makes them even more exclusive and special. Whether you are an adventurous traveler who wants to experience the cultures of each region, or a foodie who loves discovering new flavours, Japan’s varieties of unique fruits promise to make your culinary journey unforgettable. In the spirit of Golden Week, let’s first take a look at five golden fruits which are unique to Japan!
1. Hassaku – The Hybrid Citrus from Hiroshima
The hassaku (八朔) is a natural citrus hybrid between the pomelo and mandarin, with characteristics resembling its pomelo parent more. It was first discovered in the Edo period (1603 – 1868) in at the Mitsugon Jōdo-ji Temple (密厳浄土寺) on In’noshima Island (因島), located in present-day Onomichi City in Hiroshima Prefecture. The name of the fruit refers to the first day of August in the old Japanese lunar calendar, the period when it was said to be eaten in the past.
Although a little less juicy than its relatives in the citrus family, the hassaku offers a balanced mix of sweetness and sourness that is gentle on the palate. Some might even find a tinge of bitterness as the fruit contains naringin, a naturally-occurring flavonoid commonly found in grapefruits. The appearance, texture and taste of the fruit differs with its varieties, from the juicer beni-hassaku (紅はっさく) with a slightly more intensely coloured skin, to the wase-hassaku (早生はっさく) which has a thinner skin and ripens earlier than the typical hassaku.
Best time to enjoy: January to April

2. Lemon – The Refreshing Companion to Summer
A more world-renowned member of the citrus family, lemons have been cultivated in Japan since the Meiji period (1868 – 1912). As the lemon plant requires warm temperatures and lots of sunlight in its cultivation process, you can find Japan’s top lemon-producing prefectures clustered on the western side of Japan near water bodies. In particular, the “Setouchi Lemon” (瀬戸内レモン), one of the most famous lemon brands in Japan, is produced by the surrounding prefectures of the Seto Inland Sea (瀬戸内海 Seto-naikai) such as Hiroshima, Ehime and Kagawa.
Blessed by its climate and geography, Hiroshima Prefecture produces more than 50% of Japan’s lemons and is synonymous with the “Setouchi Lemon” brand. Hiroshima lemons have a mild fragrance, a mellow sour taste, and are produced with high safety standards. (Did you know that Hiroshima produces eco-lemons (エコレモン), whose skin are actually edible?) This makes the Hiroshima lemon the perfect companion to many culinary delights; from fresh seafood and kara-age (Japanese fried chicken), to flavourful desserts and beverages that are easily enjoyed by all.
Besides hassaku and lemons, the Seto Inland Sea Region is known for all kinds of juicy citrus fruits! Check out our other article for 5 more you probably have never heard of!

3. Mango – The Golden Pride of Miyazaki
Although mangoes are produced mainly in South and Southeast Asia, Japan also produces upwards of 3,000 tons of mangoes annually. Favouring a tropical climate, more than 95% of domestically-grown mangoes come from the prefectures of Okinawa, Miyazaki and Kagoshima in the southern Kyūshū region. Despite appearing in Japan since the Meiji period, their production experienced a steep growth only in recent decades.
Miyazaki Prefecture is famous for a brand of Irwin mango called the Taiyō-no-Tamago (太陽のタマゴ), which literally translates to the “Egg of the Sun”. Farmers wrap these mangoes in a net and wait for them to ripen fully and naturally drop from the trees. Subsequently, these harvested mangoes go through a stringent check based on their appearance, weight and sweetness, before they can be qualified as Taiyō-no-Tamago mangoes. These red pouches of rich sweetness are of the highest quality a fruit can offer, and are often presented as gifts, so look out for these if you are hunting for specialty souvenirs on your next trip to Miyazaki!

4. Gold Kiwi – The Smooth and Sweet Gold Variant
There are a variety of kiwis grown in Japan: the more common Hayward variety can be identified by its dull brown skin and juicy green flesh with a good balance of sweetness and sourness. On the other hand, golden kiwis have smooth, tanned skin with yellow flesh that is aromatic and sweeter than their green-fleshed cousins.
Golden kiwis of the King and Zespri varieties are grown mainly in Saga Prefecture. Although golden kiwis are difficult to grow, the experienced hands of Japanese cultivators and advanced technologies have made it possible to produce high-quality golden kiwis with a strong sweet flavour that can be enjoyed by all.

5. Jabara – The Healthy Flavours of Wakayama
The jabara (じゃばら), similar to the hassaku, is another member of the Japanese citrus family. It is a naturally occurring hybrid between the yuzu and another pomelo-mandarin hybrid, and was first discovered in Wakayama Prefecture of the Kansai region. Even today, more than 80% of jabara produced in Japan come from Wakayama.
The jabara fruit is typically the size of a baseball and has an outer skin that turns from green to yellow as it ripens. It comes into season from December to February. If you were to take a bite of its yellow flesh, an initial wave of acidity would hit your tongue, followed by a light touch of bitterness. Its sourness is so intense that it was historically said to be consumed to purge toxins and colds, literally 邪気を祓う (jaki wo harau, to purge toxins or malice).
The practice is not without reason; the jabara fruit is packed with vitamins and beneficial nutrients, with recent studies in Japan pointing to its potential effects in relieving hay fever and allergies. Today, the jabara is too sour to be sliced and consumed like oranges. However, its uniquely scented juice makes it perfect as aromatic flavouring in juices, ponzu sauce and marmalade.
