Image Generation Prompt Localization: Industry-First* 3-Slot Independent Management + Component Sharing
*As of May 2026, according to company research. This is the first tool to implement 'independent component management (character/state/background) + component sharing,' based on comparisons with over 20 domestic and international paid and free services, including Civitai, Midjourney --cref, and getimg.ai.
Since early 2026, the public and commercial use of generative AI for images, music, and videos has accelerated. However, this rapid adoption has highlighted a serious issue among Japanese users: the AI's inability to correctly handle fine context and pronunciation in Japanese.
'Japanese Gacha'—a phenomenon where users must retry prompts repeatedly because the AI fails to understand the context of the same input—has become a significant barrier to efficiency in production environments. 'AI Nihongo Lab' provides three free tools to correctly process Japanese for these AI types.
WEB-WING, a computer system development company, released the suite on May 15, 2026. The tools address issues such as character misreadings in Suno, difficulty with Japanese in image generators, and incorrect speech generation in video AI, utilizing specialized pre-processing technology.

The core image generation prompt localization tool applies the 'cel design philosophy' long used in the animation industry to 'independent management of character, state, and background,' creating the first '3-slot independent management + component sharing' system. It also includes a specialized dictionary of 300 Japanese terms.
Simultaneously, a Japanese lyric optimization tool for Suno and a dialogue conversion tool for video generation AIs (Veo 3.1 / Wan 2.7 / Sora 2 / Grok) were released. All tools are free and do not require registration.
