Flag of Musashimurayama Tokyo (Japan) - Color Morphing Mug Design

This is the official flag of Musashimurayama, a city in Tokyo Prefecture, Japan, set as a white emblem on a deep prussian-blue field.

Visual Elements & Composition

Prussian blue fills roughly eighty-five percent of the flag, so the composition reads as one dark, unbroken field. The white emblem sits at the centre and takes up the remaining fifteen percent. Its flat, vector-clean shapes give the design a restrained, modern look. The emblem is built from two stylised katakana characters, "mu" (ム), which are reshaped into a dove with a circular motif at its heart. A reader who knows the characters will see the letterforms first, and everyone else will see a bird.

Meaning & Symbolism

The two "mu" characters stand for Musashi and Murayama, the names that make up the city. The dove and the central circle carry the flag's message of peace and harmony among the citizens. The city adopted the flag on November 3, 1970, and its makers meant the wider composition to reflect Musashimurayama's industrial and civic life and its capacity for unlimited growth. The dark tones and clean white icon give the municipality a formal, dignified identity.

Turning the Story in Your Hands

A mug is held and turned, so the emblem is always seen at close range and from changing angles. The design is faint when the cup is cold and comes into view as a hot drink is poured in, so the dove appears gradually, as the morning's first cup warms it. Give this to someone who wants a little Tokyo history on the table, and let the dove surface with the coffee.

Color-changing ceramic mugs with a glossy finish, black exterior, and white interior. Available in one size: 11 oz (≈330 ml). Heat-reactive coating reveals your custom design when filled with hot liquid. BPA- and lead-free, with a comfortable C-handle.

This mug brings a playful twist to the daily coffee or tea ritual. At room temperature, it looks like a simple black mug with a glossy finish. But add a hot beverage, and your chosen design fades into view, showing vivid colors against the white interior.

The ceramic body is durable enough for repeated use, while the C-shaped handle balances comfort and grip. Printing uses sublimation techniques that fuse color into the heat-reactive surface for crisp results when the design appears.

  • Material: ceramic with glossy black exterior and white interior.
  • Size: one standard size, 11 oz (≈330 ml).
  • Finish: glossy glaze with heat-sensitive surface.
  • Printing: sublimation process produces crisp, vibrant colors.
  • Safety: BPA-free and lead-free, suitable for everyday drinks.
  • Effect: design is faintly visible when cold, fully revealed when hot.

Perfect as a novelty gift or a fun personal mug, the heat-reactive design makes coffee breaks more engaging. It works well for morning coffee, afternoon tea, or hot chocolate.

  1. Daily routine: fill with any hot beverage to reveal your chosen artwork.
  2. Gifting: the “magic” reveal makes it a memorable present for birthdays, holidays, or office exchanges.
  3. Office use: sparks conversation while still being practical for everyday drinks.

Note: for best results, avoid designs that rely heavily on deep black backgrounds, as they may blend with the mug’s surface when cold.

Unlike standard mugs, color-changing mugs require gentler care to preserve the heat-reactive coating. Hand-wash only — avoid the dishwasher and abrasive scrubbers, which can damage the finish and reduce the effect.

The mug is safe for short microwave use when heating liquids, but repeated high-heat cycles may shorten the lifespan of the coating. Always allow the mug to cool before washing.

Available in one classic size: 11 oz (approximately 330 ml). It’s large enough for most standard coffee makers and fits comfortably in most cabinets.
