Gengo Sort: Sengoku–Edo is a simple yet thoughtful puzzle game that helps you understand when Japanese historical era names (nengō) appeared and what periods they represent.
If you enjoy Japanese history through dramas, novels, games, or anime, this app offers an easy way to grasp the historical “sense of time” behind each era name.

During Japan’s Sengoku and Edo periods, era names changed frequently—often due to official or ceremonial reasons rather than major historical turning points. This can make it difficult to understand where an era fits within the broader timeline.
Gengo Sort helps you build that intuition naturally.

◆ What you can do

• Sort era-name cards into the correct chronological order
• Learn each era’s approximate time range at a glance
• Use optional hints to get brief context about events, conditions, or figures active around that era
• Unlock detailed explanations after completing the puzzle
• Develop an intuitive understanding of the flow of Japanese history

◆ Why this app helps you learn

Instead of memorizing era names from a list, you interact with them visually by arranging them in order.
This light, puzzle-like approach makes it easier to remember when an era appears and how it relates to the eras before and after it.

When an era name appears in a story—“during Tenshō,” “in the An’ei years,” etc.—you will be able to imagine the surrounding period and what was happening at the time.

◆ Perfect for

• Fans of Japanese history, samurai dramas, or historical fiction
• Learners who encounter era names in anime, manga, or games
• Students who want to reinforce timelines in a simple and intuitive way
• Anyone curious about the flow of Japan’s past

◆ Easy to play

Just drag each card to the correct position.
When you finish, you’ll see the full timeline from the Sengoku period through late Edo, along with readings, dates, and optional explanations.

Whether you’re new to Japanese history or returning to it after some time, Gengo Sort: Sengoku–Edo offers a clear and enjoyable way to connect era names with the world they belonged to.
