Create the bold lettering seen on Japanese oshi-katsu cheering fans (uchiwa) held up at idol, K-pop, theater, and concert events — entirely in your browser, on a PC or phone. Type your favorite's name or a fan-service phrase (one word per line) and it renders live, stacked vertically the way fan lettering is arranged. The defining feature of uchiwa lettering — the outline — can be stacked up to three layers, each its own color from inside out (for example black → white → light blue), so the letters read as bold, three-dimensional bubble text even from a distance. The fill can be a solid color or a top-to-bottom two-color gradient; pick a Gothic (bold), rounded, or Mincho font, and adjust the outline width and letter size with sliders. The background can be transparent (a PNG to layer over your own design), white (ready for convenience-store printing), or a solid color. When it's ready, download a PNG, or hit Print to output just the lettering on a blank page — print it at A4 to send to a convenience-store net-print service, or print at home and cut it out as a stencil. All drawing, saving, and printing happen inside your browser (canvas); the text you type is never uploaded, stored, or sent to a server. This tool focuses on the lettering itself; it does not bundle or distribute any merchandise images or photos.
