Why Japan?

Japan is the third-largest App Store market by revenue. Most indie apps have zero Japanese metadata, meaning competition for localized keywords is dramatically lower than in the US.

How Japan users search

Japanese users search in hiragana, katakana, and kanji. A single English keyword field produces zero Japanese search results for your app.

KEY FACT

Japanese users search exclusively in Japanese — English metadata is completely invisible.
