Okaishi no Taiyo"
Taiyo Co., Ltd. (Location: 293 Iikura, Sōsa City, Chiba Prefecture; Representative Director: Masakatsu Kataoka), which operates "Okaishi no Taiyo," a confectionery store long beloved in Chiba Prefecture, will hold a one-day-only "Mother's Day Tart Festival" on Sunday, May 10, 2026, as the fourth and final installment of its Mother's Day limited-edition sweets.
## Background of the Project: The "True Feelings of Mothers" Heard Because of Long-standing Love
Until now, Mother's Day at "Okaishi no Taiyo" has always featured a lavish 5-inch whole cake.
However, from customers who have grown older with the brand, we started hearing the earnest feelings: "It's a bit tough to eat a whole cake now," and "I want to enjoy various flavors a little at a time."
Because it's Mother's Day, a special day once a year, we wanted mothers to forget any reservations and indulge in many "delicious" treats to their heart's content. With this in mind, this year, we chose the format of a "Tart Festival," featuring a total of nine types of tarts, packed with the "joy of choosing" and "exciting luxury."
## Our Commitment to Tarts
Taiyo's tarts are genuinely crispy and delicious, with a special taste that reveals its "difference" in just one bite.
For the tart base, we generously use a luxurious pâte sucrée dough, lavishly kneaded with expensive almond powder and butter. It's a highly popular tart dough that achieves both fragrant richness and a light texture.
Based on this meticulously crafted tart, all nine types were newly developed exclusively for "Mother's Day." Finished with a special Mother's Day touch, each tart offers a different charm, such as fruit, chocolate, matcha, and pudding. We are confident that no matter which one you choose, you'll feel, "I'm glad I picked this one." Please enjoy Taiyo's heartfelt "Mother's Day only" special tart festival.

"Which one should I eat first?" The moment the box is opened, Mother's eyes sparkle.
Imagining such a scene, we baked "the most luxurious" fruit tart for this day.
The star of the show is the overflowing arrangement of 7 colorful fruits.
Sweet and sour strawberries, fragrant melon, bursting muscat grapes, skin-on oranges with a slightly bitter aftertaste, juicy oranges dripping with juice, blueberries, kiwis—with every bite, the juice of different fruits bursts into your mouth, filling all five senses with the freshness of early summer.
Our proud "Golden Pâte Sucre Tart" firmly receives that intense fruit juice.
Baked fragrantly with abundant expensive almond powder and finest butter, the tart is surprisingly crispy. Furthermore, by thinly coating the inside with milky white chocolate, we protect the fruit's moisture, ensuring you can enjoy the perfect "crispy and juicy" contrast until the very last bite.
Layered on top are our velvety smooth homemade custard and pure fresh cream from Kyushu. Both are filled with the sweet richness of milk, offering a blissful melt-in-your-mouth experience. This happiness, as the fresh fruits gently wrap around and melt with the fragrant butter with every chew, is truly indescribable.
