敬語道場 — Keigo Dojo

A browser-based Japanese honorific practice game. No frameworks, no build step — just one HTML file.

---

Overview

Keigo Dojo is a single-file HTML5 game for practising keigo (敬語), the formal register of Japanese. Each round presents a plain-form verb and asks you to produce the correct honorific form — either sonkeigo (尊敬語, elevating the other person) or kenjōgo (謙譲語, humbling yourself).

The game ends when you exhaust all 5 lives. Your score is tracked across the session with a streak multiplier for consecutive correct answers.

Visual Feedback

State	Background	Meaning
尊敬語 question	Blue gradient	Elevating the other person's action
謙譲語 question	Green gradient	Humbling your own action
Wrong answer	Red flash	Incorrect — one life deducted

The top border of the card and the background shift colour with each question type so you always have an ambient reminder of which register you are practising.

Scoring

Event	Points
Correct answer	+10
Correct answer (3+ streak)	+20 (2× multiplier)
Wrong answer	0 (−1 life)

A streak counter is shown in the stats bar. It resets on any wrong answer.

Lives

You start with 5 lives (♥♥♥♥♥). Each wrong answer removes one heart. The game ends immediately when all five are lost. Your final score is shown on the game-over screen.

Project Structure

keigo-dojo/
└── index.html    ← entire game (HTML + CSS + JS, self-contained)

Everything — markup, styles, game logic, and verb data — lives in a single file. There are no external dependencies beyond Google Fonts (loaded via CDN), so the game works fully offline if you remove the font import or cache it locally.

---

Customisation

All verb data is stored in the VERBS array near the top of the <script> block in index.html. Each entry follows this shape:

{
  base: "する",           // plain form shown to the player
  reading: "suru",       // romaji reading shown below
  meaning: "to do",      // English gloss shown in italics
  sonkeigo: "なさる",    // correct sonkeigo answer
  kenjougo: "いたす",    // correct kenjōgo answer
  decoys: [              // extra wrong answers specific to this verb
    "ございます", "おっしゃる", ...
  ]
}

To add more verbs, append objects in the same format to the VERBS array.

To change the number of lives, find lives: 5 in the state object and update it.
