Separate the three language decisions
The website interface helps you navigate, an explanation language helps you understand feedback, and Japanese is the language you are practicing. These roles can overlap, but they do not have to be identical. A learner can read advanced Japanese while still preferring a familiar language for a subtle grammar explanation.
The browser’s installation dialog adds another layer: its words come from the browser or device, not solely from the site. If a guide says Add to Home Screen and the menu uses a local equivalent, compare the function rather than expecting every screen to use the same literal phrase.
Describe the explanation you need
Instead of requesting only “make it easier,” say whether you want simpler terminology, a translation into your preferred language, or an easier Japanese example. These adjustments solve different problems. A precise request helps Mocchi preserve a useful challenge while removing an unnecessary barrier to understanding.

| Difficulty | Useful request |
|---|---|
| Unfamiliar explanation language | Explain this point in my preferred language. |
| Dense grammar terminology | Use everyday wording and one short comparison. |
| Japanese example too advanced | Keep the same point but use simpler vocabulary. |
Check the installed entry with a real learning task
After installation, launch the entry and inspect the account and language. Then ask for a small explanation and respond to its question. This verifies more than an icon label. If a route opens in an unexpected language, choose the preferred site language and check the destination again before assuming the installation created a different learning profile.
Keep Japanese level grounded in performance
Choose difficulty based on what you can read, understand, or produce, rather than which language appears in the menus. Tell Mocchi when a sentence is easy to recognize but difficult to say, or when you understand the vocabulary but miss the grammar relationship. Those details support a more useful next task than a broad label alone.
Use feedback to refine the language balance
As your Japanese develops, you may want more Japanese examples, shorter translations, or occasional explanations entirely in Japanese. You can request that gradually. There is no need to abandon a helpful explanation language to prove progress. The practical goal is understanding the point well enough to use it in a new sentence, with the interface and installed entry making that practice easy to reach.
