Experience a unique blend of culture and beverage with this Flag of Meguro Tokyo Japan - Color Changing Coffee Mug. This mug showcases the iconic design of the Meguro ward's flag, a vibrant representation of traditional Japanese aesthetics. The flag features three vertical stripes in the colors of red, white, and green, symbolizing courage, purity, and harmony respectively. The central emblem is a stylized cherry blossom branch, reflecting the area's rich cherry blossom history.

But what sets this mug apart is its thermochromic coating, which adds an interactive element to your drinking experience. When hot liquids are poured into the mug, the flag design subtly changes color, creating a beautiful visual transition that mirrors the changing seasons. Perfect for anyone who appreciates unique and cool drinkware, this Flag of Meguro Tokyo Japan - Color Changing Coffee Mug is a thoughtful gift for travelers, city enthusiasts, or anyone with a soft spot for Japanese culture.

Note: The thermochromic effect may vary based on the temperature of the liquid and the individual mug. The colors will return to normal once the liquid cools down or is removed.

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.
