The "umeboshi" and "ume juice" you buy casually at the supermarket...
Can you actually explain to your child how these are made?
Minabe Town, Wakayama Prefecture — the home of Japan's most prestigious plum brand, "Nanko-ume."
Here you can experience making your own "My Umeboshi" blended to your personal taste, or making sweet "ume syrup (ume juice)" using large, authentic local plums.
The greatest appeal of this experience is that the "food education" continues for a long time after you return home from the trip.
The ume syrup making in particular becomes the ultimate independent science project — every day after you get home, you shake the jar you brought back as a souvenir and observe as the rock sugar dissolves.
About a month later, the moment a child proudly drinks the amber-colored syrup diluted with water or sparkling water and declares "I made this ume juice!" — that smile will be a lifelong family memory.
In this article, we'll thoroughly guide you through the appeal of the "ume experience" for learning about Japan's traditional preserved food wisdom, along with a fully satisfying sightseeing model course through Nanki Shirahama!
Tips for Enjoying the Ume Experience as a Family (30 seconds)
- Learn the magic of "preserved food": Discover the wisdom of our ancestors who used salt and sugar to keep food fresh in the days before refrigerators.
- Blend your preferred flavor: Even children who don't like sour food can make a "sweet umeboshi" loaded with honey — so everyone's covered.
- Observation diary after you get home: Shake the ume syrup jar every day and observe with the family as the plums gradually shrivel as they release their extract.
- Perfect combination with Shirahama sightseeing: From the experience facility in Minabe Town to "Nanki Shirahama (Adventure World)" with its pandas is just a short drive! The ultimate family travel route is ready to go.
1. [Deep Dive] Why Doesn't Ume Spoil? The Magic of "Salt and Sugar"
Before the experience, let's explain to children the wonderful science behind Japan's preserved foods: "Why do umeboshi and ume syrup last so long without going in the refrigerator?"
The Power of "Osmosis" — Drawing Out the Water
Food spoils because bacteria (microorganisms) use the "moisture" inside food to multiply.
So long ago, people coated plums generously with "salt" or "sugar (rock sugar)."
Then the power of a science principle called "osmosis" kicks in — the moisture inside the plum is squeezed out toward the salt or sugar! With no moisture available, bacteria cannot survive, and the food lasts much longer.
Furthermore, that delicious moisture that gets drawn out is exactly what becomes the sweet, concentrated "ume syrup."
2. Sour or Sweet? How to Choose the Experience Menu Kids Will Love
At Wakayama's experience facilities, you can generally choose from two types: "Umeboshi Making" and "Ume Syrup (Juice) Making."
| Experience Menu | Features & How to Choose |
|---|---|
| My Umeboshi Making |
[Great for Kids Who Love Onigiri & Rice!] Using pre-salted plums, you blend several types of seasoning liquid (honey, bonito, shiso, etc.) in your preferred proportions and pickle them. "I want mine sour!" "I'm going for sweet!" — be the designer of your own flavor. Ready to eat in about 2 weeks. |
| Ume Syrup (Juice) Making |
[Great for Toddlers and Kids Who Love Experiments!] The simple process of layering green plums (or frozen plums) and rock sugar alternately in a jar means even small children can participate happily. Since you can observe the rock sugar dissolving every day after you get home, it's ideal for independent research projects! |

The iconic symbol of Shirahama — brilliant emerald-green sea and powder-white sand that makes you think "Is this Hawaii!?"
In summer it's packed with swimmers, but even out of season, just walking barefoot on the white sand or searching for shells along the water's edge makes for wonderful memories. This is a certified "Sister Beach" of Waikiki Beach in Hawaii.
6. Sea and Onsen After Ume-Making! Recommended Family Accommodations in Wakayama
After being enveloped in the lovely scent of ume while making your syrup and being charmed by pandas at Adventure World, refresh yourselves fully at a resort overlooking the beautiful sea of the Nanki coast!

7. [After You Get Home] Shake the Jar Every Day! An At-Home "Ume Syrup" Observation Diary
After returning from the trip, place the precious jar you carefully carried home in a cool spot in the living room. This is where the second chapter of the "food education experience" begins!
3 Ways to Care for Your Ume Syrup
- ① Gently shake the jar once every day! (Once extract starts coming out, tilt the jar daily to help the rock sugar dissolve faster and to keep the surface of the plum coated with syrup so mold doesn't grow. A wonderful daily chore for children!)
- ② Observe the shriveling changes (Watch as the firm green plums gradually become "wrinkled" as osmosis draws out their extract)
- ③ Complete in about 3 weeks to 1 month! (Once the rock sugar has completely dissolved and the syrup turns amber, it's done! Dilute with water or sparkling water and toast to "the best ume juice we've ever had!")
🏺 A Beautiful Addition to Your Kitchen! Welcome a Lifelong "Storage Jar"
If you're moved by the deliciousness of your homemade ume syrup, why not try your hand at "ume-shigoto" (ume preservation work) from scratch at home next year? Storage containers for pickling ume and making fruit wine come in beautifully designed styles that look stunning displayed in the kitchen. Here are some lifelong glass jars and enamel containers to add beauty to the Japanese kitchen.
Conclusion: The Flavor You Preserved with Your Own Hands Makes You Love Japan's Food Culture
"Dad, look! All the sugar has dissolved!"
Even after returning from the wonderful trip to Wakayama, every time you see the "ume syrup jar" in the corner of the living room, happy memories of the trip come flooding back.
Carefully shaking the jar with your own hands every day, patiently nurturing the amber-colored syrup over time...
The moment you pour it over ice in a glass, mix it with sparkling water, and drink it — the "So delicious!" reaction is something you can never get from a vending machine drink.
"Food takes time to make."
"Salt and sugar have the power to protect food."
The knowledge and taste education gained through this experience will become a lifelong treasure for children.
This weekend, why not set out on a trip to Minabe Town, Wakayama — where you can enjoy pandas and an ocean resort while learning Japan's "sour magic"?
