Papaya
What Is Papaya?
Papaya is a representative tropical fruit enjoyed throughout tropical regions around the world, as well as in some subtropical areas.
With its vibrant flesh and rich nutritional value, it has long been cherished worldwide and is often referred to as the “Golden Fruit” or “Medical Fruit.”
In Japan, it is also known by alternative names such as Mokua and Manjugua.
Among all varieties, papayas grown on Hawaii’s Big Island are truly exceptional.
Abundant tropical sunshine combined with cool evening air—this natural difference between day and night temperatures concentrates flavor within the fruit, enhancing its sweetness and aroma.
Moreover, the lava-rich soil spread across the foothills of Kīlauea Volcano, which remains active today, is rich in minerals and provides an ideal growing environment.
This unique climate and soil give rise to papayas with deep sweetness and a rich, fragrant aroma.
It is said that Christopher Columbus once praised papaya as the “Fruit of the Angels.”
A gift of the tropics shaped by nature and history—papaya continues to captivate dining tables and hearts around the world.
Varieties
① Kapoho Solo
Hawaiian Kapoho Solo papaya is one of the finest varieties within the Solo group, cultivated in the Kapoho district at the foothills of Kīlauea Volcano on the Big Island of Hawaii.
When fully ripe, the skin turns a vibrant yellow, and when cut open, the black seeds are neatly gathered at the center—making it easy to handle and prepare.
Its flavor is mellow and refined, with a gentle sweetness and no overpowering aftertaste.
A delicate, floral aroma softly spreads, while the flesh melts smoothly in the mouth, releasing rich tropical flavors the moment it is tasted.
With very mild acidity and almost no characteristic bitterness, it is an excellent choice for first-time papaya eaters and children alike.
This deep sweetness and aroma are nurtured by mineral-rich volcanic soil and Hawaii’s distinctive climate, marked by significant temperature differences between day and night.
It is truly a premium tropical fruit that Hawaii proudly offers, shaped by the power of nature and the land.
② Sunrise
Hawaiian Sunrise papaya is a high-quality tropical fruit distinguished by its beautiful red-orange flesh.
Developed through selective breeding in Hawaii, this variety turns bright yellow when fully ripe.
Its flesh, reminiscent of a glowing sunrise, is the inspiration behind the name “Sunrise.”
In addition to a sweetness comparable to Kapoho Solo, Sunrise papaya offers a subtle, refreshing acidity that creates a lighter and cleaner finish.
Currently cultivated mainly within the Hawaiian Islands, it is a rare variety in Japan, available only in limited quantities and during specific seasons.
With its vivid flesh color and fresh, balanced flavor, Sunrise papaya has quietly gained popularity among fruit enthusiasts.
Nutritional Value & Health Benefits
Papaya is a fruit packed with nutrients that support the body, in addition to its tropical sweetness and refreshing aroma.
In particular, the following three points deserve special attention:
1. Rich in Vitamin C for healthy skin and stronger immunity
Papaya contains over 50 mg of vitamin C per 100 g,
which is a relatively high amount compared to many common fruits.
Its antioxidant properties help maintain healthy skin and support the immune system.
2. Dietary fiber that supports digestive health
Papaya provides a well-balanced combination of soluble and insoluble dietary fiber,
containing approximately 1.3 g of fiber per 100 g.
It helps promote regular digestion and contributes to improving the intestinal environment.
3. Vitamin A (β-carotene) essential for beauty and overall health
Papaya is also rich in β-carotene, which is converted into vitamin A in the body.
This nutrient supports eye health and skin maintenance.
The fruit’s vibrant orange color is a visible sign of its nutritional richness.
In addition, papaya contains micronutrients such as potassium and folate, allowing for well-balanced nutritional intake.
By incorporating papaya into daily meals, it helps support beauty and health from within—earning its reputation as a “fruit-based supplement.”

Storage & Ripening
Papaya is a climacteric fruit, meaning its sweetness and aroma continue to develop after harvest.
To enjoy it at its best, identifying the right ripening stage and proper storage is essential.
Ripening: Room Temperature Storage to Enhance Sweetness and Aroma
A short ripening period is the key to bringing out papaya’s full flavor.
1. When is it ripe?
When the skin turns a bright yellow overall and the fruit yields slightly when gently pressed, it is ready to eat.
2. Ripening environment
Store papaya at room temperature (20–25°C) in a well-ventilated area, away from direct sunlight.
3. To speed up ripening
Place the papaya in a paper bag together with apples or bananas.
The ethylene gas released by these fruits helps accelerate the ripening process.
Storage: Gentle Refrigeration After Ripening
Fully ripe papayas are very delicate.
To avoid missing the peak of sweetness, store them in the refrigerator once they reach the ideal ripeness.
1. Storage after ripening
Refrigerated storage is recommended for up to 2–3 days.
2. Storage after cutting
Wrap the cut surface with plastic wrap or place the pieces in an airtight container and refrigerate.
It is best to consume within the same day or the following day.
Important Note: Do Not Refrigerate Unripe Papayas
Refrigerating papayas before ripening will prevent their sweetness and aroma from fully developing.
Rule to remember:
Room temperature before ripening → Refrigeration after ripening
By following this rule, you can fully enjoy the unique qualities of ripening-type fruits like papaya.
How to Eat Papaya
Easy for First-Timers: Basic Papaya Cutting Method
1. Cut lengthwise in half
Place the papaya on a cutting board and slice it lengthwise into two halves.
You will see the black seeds gathered in the center of the flesh.
2. Remove the seeds with a spoon
Gently scoop out the seeds and the surrounding gelatinous pulp with a spoon.
This part is not eaten, so be sure to remove it completely.
3. Cut the flesh
Cut each half into wedges and then into bite-sized pieces, if desired.
Alternatively, the flesh can be scooped directly with a spoon and enjoyed as is.
【Papaya Boat】
In addition to enjoying papaya simply sliced, a popular serving idea is the “Papaya Boat.”
Cut the papaya in half and use it like a boat, topping it with yogurt or ice cream for an easy and delicious arrangement.
