Horizontal & Vertical Japanese Text Converter
Convert Japanese text between horizontal and vertical writing with customizable column spacing and split logic.
Use the buttons to convert in either direction; column spacing relies on full-width spaces.
Horizontal Text Split Method
Split your horizontal text using a specific character, word, or spacing pattern—leave blank to use both half-width and full-width spaces automatically.
Use \n for line breaks, \t for tabs, \u3000 for full-width space. Leave blank to split on both half-width and full-width spaces.
Column Gap
Quickly transform Japanese text between yokogaki (horizontal) and tategaki (vertical) layouts. Fine-tune column spacing, choose fixed character widths or custom delimiters, and preview the vertical composition instantly—perfect for typography, design, and study materials.
