Flag of Koganei Tokyo Japan - Tumbler 20oz

This design takes the official municipal emblem of Koganei, a city in Tokyo Prefecture, and turns it into a bold, minimalist mark that reads as both writing and flower.

Visual Elements & Composition

The palette is restrained: a deep red and a generous field of white. The red does most of the work, forming the central motif against the open white ground. The composition is centred and symmetrical, built from circles, ovals and a crescent ring, with pointed leaf shapes sitting around the core. Its flat vector construction keeps every line clean, so the emblem reads clearly at a glance.

Meaning & Symbolism

At the heart of the emblem is the kanji 小 (ko), the first character in the city's name. The artist has shaped it into a cherry blossom, fusing written language with one of Japan's most familiar floral motifs. The city adopted this symbol officially on October 1, 1958, and it serves as a formal emblem of regional heritage and civic pride. It is a neat example of how Japanese heraldry, or mon, can carry a place's identity in a single compact image.

Made for the Tumbler

A tumbler is a tall, curved surface that wraps around the hand, so the emblem never sits still. As you turn it, the red blossom moves in and out of view and the white field frames it from every angle. Because the design is built from simple, centred shapes, it holds its shape around the full curve of the tumbler rather than breaking up at the edges. It's a quiet, cheeky way to carry a piece of Tokyo heraldry with you every day.

20 oz vacuum-insulated stainless steel tumbler with a glossy exterior, clear push-on lid and rubber gasket. Built for all-day temperature control and everyday knocks — a solid choice for commuters, desks, and on-the-go routines.

The tumbler’s double-wall vacuum core keeps hot drinks hot and cold drinks cold longer than a single-walled cup. Stainless steel resists staining and rust, while the glossy finish makes it easy to wipe clean and gives a polished look on the go.

The clear lid snaps into place and uses a rubber gasket for a dependable seal (not leak-proof if tipped, but very good sitting upright). Rounded edges make the body comfortable to hold; the slimmer lower diameter slips into most cup holders but still feels substantial in hand.

  • Construction: vacuum-insulated, double-wall stainless steel for effective temperature retention.
  • Capacity: 20 oz (≈0.59 L) — room for a generous coffee or a tall iced drink.
  • Lid: clear push-on lid with a rubber gasket for a snug fit and reduced spills while upright.
  • Finish: glossy exterior that cleans easily and shows color well for wraparound prints.
  • Practicality: durable, corrosion-resistant, and suited to daily carrying and travel.

This tumbler is made for real life: commuting, desk days, long errands, and outdoor breaks. Its insulation keeps your drink closer to the temperature you poured in, so it’s handy for slow sippers and long meetings alike.

  1. Commute ready: fits many car cup holders and keeps drinks at serving temperature during travel.
  2. Daily desk cup: reduces trips to the kettle and keeps cold drinks chilled through the afternoon.
  3. Outdoor use: sturdy for picnics, hikes, and casual outdoor work — rinse and reuse without fuss.

Quick tip: if you want a quieter lid, remove the gasket and rinse it separately — it will snap back on without tools.

Dishwasher-safe for convenience, though hand-washing the lid and gasket will keep seals fresh longer. Remove the rubber gasket occasionally to clean the channel — trapped moisture is the usual cause of lingering odors.

Avoid bleach, oven use, and the microwave. If you hand-wash, use warm water, mild soap, and a soft sponge; dry fully before storing to prevent trapped moisture. Replacing the gasket after a long period of heavy use helps maintain a tight seal.

One size: 20 oz (≈0.59 L). Dimensions below help with shelf placement, cup-holder fit checks, and packaging decisions.
