Create the Matrix digital rain effect on a full-screen black canvas: columns of falling green katakana glyphs with a trailing fade and a brighter leading character.

**Developing Digital Rain**

I'm currently focused on rendering the core visual elements. The plan is a full-screen black canvas with columns of katakana glyphs cascading down, incorporating a subtle fade trail and a highlighted leading character.

**Implementing Core Logic**

My focus has shifted to the actual implementation details. I'm structuring the HTML with inline styles and a canvas element, then diving into the JavaScript. The immediate tasks are setting up the canvas context, handling resizing, defining the character set, and initiating the drawing loop to manage column drops and fading effects.

**Refining Drawing Loop**

I'm now refining the drawing loop. The strategy involves iterating through column drops, applying a semi-transparent black fill for fading, drawing the katakana characters with a specific green hue, and ensuring the leading character in each column stands out distinctly.
