Word lists and flash card apps teach Japanese words out of context: a random noun, then an unrelated verb, then another noun. Nothing connects, so little sticks, and you have no real sense of which parts of daily life you can actually talk about.
Nihongo Tree grows about 6,800 everyday words like a bonsai. Areas are limbs, themes are branches, word groups are twigs, and every word is a leaf that turns green as you learn it. Words are grouped the way you meet them, in the kitchen, the convenience store or the train station, so related words stick together.
Start at the trunk, pick an area of daily life, and drill into the themes inside it. Every word has furigana, romaji, a meaning and its JLPT level.

Readings over every kanji, switched on or off in one tap. Romaji and English toggle too, so you can lean on them early and drop them later.
Every word and every example sentence has audio, so you learn how it sounds, not just how it looks.
Study any word group as flash cards, and drill verb conjugations until they come without thinking.
Each word carries its JLPT level from N5 to N1. Filter to focus on exactly what your exam needs.
Mark words as known and the leaves turn green at every level, from a single theme up to the whole tree.
Yes, completely. There is no account, no subscription and nothing to install.
Beginners through upper-intermediate. Every word carries its JLPT level (N5 to N1), so you can filter to the words you need.
The JLPT has not published an official vocabulary list since 2010, so levels follow Jonathan Waller’s widely used community lists (tanos.co.uk). Treat them as a guide.
Knowing hiragana and katakana helps. Kanji always has furigana available, and romaji can be switched on while you are starting out.

Yes. It works in any modern mobile browser.
