Jiji bananas are a Taiwanese banana grown along the Green Tunnel in Jiji Township, Nantou, known locally as "mountain bananas" (shan jiao); the main cultivar is Beijiao, with thin skin and high sugar content that older generations regard as the definitive authentic Taiwanese banana flavor. At one end of the camphor tree Green Tunnel next to Jiji train station is a famous attraction, and at the other a row of banana stalls; the most common mistake travelers make is biting into a bright yellow banana right away — wait until the skin turns yellow with black spots for peak sweetness.
In Jiji, "mountain bananas" (shan jiao) refer to bananas grown at elevations above 250 meters, concentrated around Jiji Township in Nantou, prized for their sweet, moisture-rich flesh. Jijibanana Tourist Factory is Taiwan's only ecological park dedicated to mountain bananas, cultivating more than 110 banana varieties on site. Note: Taiwan's Ministry of Agriculture-promoted "Tai-Chiao No. 1" cultivar was bred from Beijiao through tissue-culture variation selection as a Panama-disease-resistant variety (officially named and promoted in 1992) — it is a distinct cultivar from traditional Beijiao, not simply interchangeable with it.
What Are Jiji Bananas
Taiwan Banana No. 1 (Beijiao) is a traditional Taiwanese variety; the fruit is medium-sized with thin skin and fine flesh, with sucrose as the primary sugar and an abundant fruity aroma — when fully ripened it can reach over 22 Brix. Jiji Township's valley topography provides long sunshine hours, and the well-draining hillside soil allows banana plants to develop deep root systems with ample nutrients. The Farmers' Association also produces dried banana (a dehydrated, concentrated version) and banana vinegar; the former intensifies the sugarcane sweetness while the latter is sweet-sour and refreshing — both use local bananas as the base ingredient.
Jiji Township Farmers' Association is the primary promotional body for local bananas; the cluster of banana stalls around the train station is a long-established part of the tourist landscape, with vendors also along the Jiji Green Tree Tunnel walkway. Bananas are available year-round with no significant off-season, though flavor is best during summer and autumn (July–October) when sunlight is most abundant. The Farmers' Association website includes descriptions of banana processed goods and lists Jiji bananas as the township's signature product.

Visitor Tips
- Ripeness varies considerably among stall bananas; pay attention to maturity when selecting — under-ripe bananas have a starchy, powdery texture and need to be taken home to ripen further.
- Some vendors sell oversized or extra-heavy banana bunches that look impressive but may not taste as good as medium-sized bunches; standard-size clusters are the better choice.
- Bananas bruise easily; after purchasing, avoid placing them at the bottom of a bag under other items — carry them upright or hanging to minimize damage.
