Suzu is a feed of short videos from Japanese creators: vlogs, street interviews, cooking, people talking about their day. Words with kanji carry their reading in kana, and Japanese and English captions run together while the word being said lights up. Tap the word you missed, and it comes back on the day you were about to lose it.
Japanese on top, English below. Written Japanese has no spaces, so the moving highlight is often the first time you see where one word ends and the next begins. You pick a level before the first clip.
A character you have never seen is still a word you can sound out, tap and keep. Tap a word for its meaning in that line and the dictionary form it came from, so 食べた takes you back to 食べる.
Save 電車 and 電話 and the 電 family starts to fill in, each word linking back to the clip where you heard it.
Saved words come back as cards around the day you would have forgotten them, and each card replays the few seconds you took the word from.
No streak to protect. Nothing to lose by leaving it alone for a week.
Videos play in the official YouTube player and belong to the creators who made them. Every clip carries the name of its channel and links back to the original.
