WaseiGo

Product Introduction

1. Definition: WaseiGo is a specialized language learning application and digital dictionary focused exclusively on Japanese wasei-eigo (和製英語). Technically, it falls into the categories of mobile/web-based educational technology (EdTech), vocabulary acquisition software, and bilingual reference tool.
2. Core Value Proposition: WaseiGo exists to solve the specific and pervasive problem of "false friends" in the Japanese language. It bridges the comprehension gap between English-looking katakana words (wasei-eigo) and their actual meanings in both Japanese and English, preventing miscommunication for learners and speakers of both languages.

Main Features

1. Illustrated Contextual Dialogues: Each of the 1,000+ wasei-eigo terms is taught not through a static list, but via a custom, watercolor-style illustrated scene. This scene frames a short, bilingual dialogue between two characters (Kenta and Emma), where the linguistic misunderstanding naturally occurs and is resolved. This method employs narrative-based learning and visual context to enhance memory retention.
2. Native-Quality Audio System: The app features a comprehensive audio layer. Every line of dialogue in both Japanese and English, as well as the standalone katakana pronunciation of each wasei-eigo term, is recorded with native-quality audio. The technical implementation allows for tap-to-listen functionality on any speech bubble, facilitating auditory learning and pronunciation practice.
3. Adaptive Quiz & Spaced Repetition Engine: WaseiGo includes multiple quiz types (meaning selection, reverse lookup, illustration matching) driven by a review system that prioritizes user performance data. It utilizes principles of spaced repetition, tracking user streaks, misses, and progress to algorithmically schedule review items, optimizing long-term vocabulary retention.
4. Bidirectional Learning Framework: The content is architecturally designed for two distinct user journeys. For English speakers learning Japanese, it explains the Japanese meaning and usage. For Japanese speakers learning English, it clarifies the true English equivalent and the potential pitfall. This dual-path structure is built into every word entry and dialogue.

Problems Solved

1. Pain Point: Directly addresses the confusion and communication errors caused by wasei-eigo—words like "コンセント (konsento)" meaning "electrical outlet" not "consent," or "クレーム (kureemu)" meaning "complaint" not "claim." This is a major stumbling block in achieving functional fluency in Japanese.
2. Target Audience: Primary personas include: 1) Intermediate to advanced English-speaking Japanese language learners, 2) Japanese speakers (ESL learners) seeking to use English correctly and avoid "Japanglish," 3) Professionals, travelers, and expats in Japan who encounter these terms in daily life and business, 4) Linguists and language enthusiasts interested in lexical borrowing and language change.
3. Use Cases: Essential for: preparing for a business meeting or customer service interaction in Japan, studying for the JLPT (Japanese Language Proficiency Test) where such terms frequently appear, consuming Japanese media (anime, TV, magazines) without misunderstanding, and for Japanese individuals writing or speaking English for an international audience.

Unique Advantages

1. Differentiation: Unlike generic Japanese vocabulary apps (like Duolingo, Memrise) or standard dictionaries, WaseiGo has a razor-sharp niche focus. It does not teach general vocabulary or grammar but provides deep, contextual, cross-linguistic analysis specifically for wasei-eigo, a category most other tools treat superficially or ignore.
2. Key Innovation: Its core innovation is the "misunderstanding-to-clarification" dialogue model paired with original artwork. This transforms a dry lexical entry into a memorable micro-story. Furthermore, its one-time purchase premium model (vs. subscription) and fully functional web-app (PWA) accessibility across iOS, Android, and desktop browsers offer significant user experience and value advantages.

Frequently Asked Questions (FAQ)

1. What is wasei-eigo? Wasei-eigo (和製英語) refers to Japanese-made words constructed from English (or other foreign) roots and morphemes, but whose meanings, usage, or forms are unique to Japanese and not used in the source language. Examples include "サラリーマン (salaryman)" for a white-collar worker and "イメージチェンジ (image change)" for a makeover.
2. Is WaseiGo free to use? WaseiGo operates on a freemium model. Users can access a full-featured selection of 50 wasei-eigo words for free, including all dialogues, audio, and quiz modes. A one-time premium purchase unlocks the complete database of 1,000+ words and all future updates, with no subscription or ads.
3. Can I use WaseiGo to learn general Japanese? No, WaseiGo is a specialized tool focused exclusively on the wasei-eigo phenomenon. It is not designed to teach Japanese grammar, kanji, or core vocabulary. It is most effective as a supplemental resource for learners who already have a basic foundation in Japanese.
4. How does WaseiGo help Japanese people learn English? For Japanese speakers, WaseiGo clearly highlights "false friends" by showing the Japanese meaning of a wasei-eigo term side-by-side with its true meaning in natural English. The dialogues model correct English usage, helping users avoid directly translating wasei-eigo, which often results in confusion.
5. Does WaseiGo work offline? The native iOS and Android apps likely support offline functionality for downloaded content, a typical feature for mobile learning applications. The web application (PWA) may have limited offline capabilities depending on browser caching. For full offline access, the native apps are recommended.
