Coffee cup sleeves, also known as coffee sleeves, are roughly cylindrical sleeves that fit tightly over handle-less paper coffee cups to insulate the drinker’s hands from hot coffee. The coffee cup sleeve was invented by Jay Sorensen in 1991. The paper-based Mizuno Sangyo Cup Sleeve features 3 distinct notches for three-stage adjustments. The three notches serve as locking tabs or slots and allow you to adjust the length of the sleeve to fit three cup sizes (such as Small, Medium, and Large, or 8 oz, 12 oz, and 14 oz cups).
Japanese shrub mint and fuki (Japanese butterbur) are both distinct perennial plants native to East Asia. While they are both shade-loving woodland plants, they belong to entirely different botanical families and offer vastly different culinary and visual characteristics.

Tenninsou, Japanese shrub mint, scientifically known as Leucosceptrum japonicum is a perennial plant native to Japan belonging to the mint family (Lamiaceae). It is primarily utilized for ornamental landscaping and gardening and for cut flowers and floral arrangements.
It is highly valued as a “shade plant” (for shaded or woodland gardens) due to its excellent shade tolerance and bright, attractive foliage. Cultivars like the ‘Golden Angel’ are popular choices to brighten up dark areas in gardens. It blooms in late summer to autumn with dense, elegant spikes of pale yellow or white flowers; therefore, it is commonly used as a cut flower or as an autumn flower for traditional Japanese tea ceremonies (chabana).

In Japanese cuisine, fuki, Japanese butterbur, is highly prized for its crisp texture and refreshing, earthy bitterness. It serves as a seasonal delicacy, with both the stalks and the early flower buds utilized in a variety of traditional and modern dishes.
Because fuki contains natural astringency, the stalks and buds must always be boiled and soaked in cold water before eating.
1. The Stalks (Fuki)
The long, slender stalks are the most commonly eaten part of the plant. After boiling, the fibrous outer skin is peeled away to reveal a pale green, tender stalk that is used in:
Simmered Dishes (Fuki-no-nitsuke): The stalks are simmered with dashi (Japanese soup stock, broth), soy sauce, and mirin (a sweet, syrupy Japanese rice wine used as a fundamental seasoning) to absorb delicate flavors.
Stir-fries (Kinpira): Strips of stalks are stir-fried with sesame oil, soy sauce, and sugar to make a sweet-spicy side dish.
Mixed Rice (Takikomi Gohan): Chopped, cooked fuki stalks (and sometimes leaves) are mixed into steamed rice along with ingredients like soy sauce and fried tofu.
Pickles: The stalks can be pickled or preserved in soy sauce for long-term storage.
2. The Flower Buds (Fukinoto)
Appearing in late winter to early spring, these flower buds are cherished as the very first sign of spring. They are known for their strong, pleasant bitterness.
Tempura: The buds are coated in a light batter and deep-fried, offering a crispy texture and a rich flavor that pairs perfectly with salt.
Red Japanese Maple or Nomura-momiji acer (Acer palmatum cv. sanguineum) is a deciduous small tree celebrated for its striking red-to-purple foliage that evolves through the seasons. Unlike standard Japanese maples (Acer palmatum) that green up in spring, the new growth of sanguineum (meaning “bloody” or “deep red”) emerges dark purple to brilliant red. In summer, the foliage tends to transition to deep green or bronze, followed by a vibrant purple-red autumn display.

Identification of the acorns summarized using the information identified by the Google AI:
Acorns, produced by trees in the genus Quercus (along with Notholithocarpus and Lithocarpus), are broadly divided into white oak (one-season maturity, low tannin) and red oak (two-season maturity, high tannin) groups. These nuts are vital for wildlife and vary significantly in shape, size, and cap structure.
Here are 24 distinct species of oak trees known for their characteristic acorns, featuring a mix of common and distinct types:
White Oak Group (1-Season Maturation, Low Tannin)
White Oak (Quercus alba): Features long, oblong-shaped acorns with a warty, shallow bowl-shaped cap.
Bur Oak (Quercus macrocarpa): Produces some of the largest acorns, distinguished by a heavily fringed or “hairy” cap that can cover most of the nut.
Swamp White Oak (Quercus bicolor): Often found in pairs, these acorns are long-stalked and light brown.
Swamp Chestnut Oak (Quercus michauxii): Known as “cow oak,” this species produces large, sweet acorns highly prized by wildlife.
Chinkapin Oak (Quercus muehlenbergii): Produces small, chestnut-brown acorns that are sweet and quickly consumed by animals.
Post Oak (Quercus stellata): Characterized by small acorns with thick, chunky caps that cover one-third to half the nut.
Chestnut Oak (Quercus montana): Features large, shiny, elongated acorns that are among the first to drop in autumn.
Over-cup Oak (Quercus lyrata): Famous for a unique, nearly enclosed, globular acorn covered by a scaly, “cupped” cap.
Live Oak (Quercus virginiana): Produces small, dark, shiny, football-shaped acorns typically found in clusters.
Blue Oak (Quercus douglasii): Native to California, this species produces acorns with very thin, shallow caps, which are a major food source in xeric environments.
Oregon White Oak (Quercus garryana): Known for large, oval acorns with a small, warty cap, common in the Pacific Northwest.
Dwarf Chestnut Oak (Quercus prinoides): A shrub-like oak producing small, thin-shelled acorns that mature quickly.
Red Oak Group (2-Season Maturation, High Tannin)
Northern Red Oak (Quercus rubra): Features large, rounded acorns with a flat, saucer-like cap that covers only the top, often described as a “beret”.
Black Oak (Quercus velutina): Produces acorns with a distinct, “shaggy” cap covering about half the nut, known for its orange inner bark.
Pin Oak (Quercus palustris): Small, round, striped acorns with a very thin, small cap.
Scarlet Oak (Quercus coccinea): Features acorns with concentric rings on the tip and a cap that often tapers.
Water Oak (Quercus nigra): Produces very small, nearly spherical acorns with a shallow cap, which often appear in huge quantities.
Willow Oak (Quercus phellos): Known for very tiny, light brown acorns with shallow caps, which are a favorite for deer and ducks.
Southern Red Oak (Quercus falcata): Small, rounded acorns (approx. 1/2 inch) that are orange-brown in color.
Shingle Oak (Quercus imbricaria): Produces small, bitter acorns, often with a striped appearance on the nut, with a cap covering up to a third.
Turkey Oak (Quercus cerris): A European species featuring a very distinctive mossy or bristly cupule (cap).
Cherry-bark Oak (Quercus pagoda): Known as part of the red oak group, its small, 1/2-inch wide acorns are a favorite for fall hunting.
Shumard Oak (Quercus shumardii): Produces large, stout, somewhat oblong acorns with a relatively shallow, scaly cap.
Nuttall Oak (Quercus nuttallii): Produces large, elongated, striped acorns that fall late in the season.
Key Identification Features
Cap Scales: Red oak caps have tight, overlapping scales, while White oak caps can be warty or bumpy.
Maturation: Red oak acorns take two years; white oak acorns take one.
Interior: White oak shell interiors are smooth; Red oak shell interiors are fuzzy.
Taste:Â White oak acorns are sweeter (less tannin); Red oak acorns a very bitter.
