How to Say ‘One thousand’ in Japanese

せん

se n

[seh n]

💬 Usage Tip: Watch two changes: さんぜん (sanzen) "3,000" and はっせん (hassen) "8,000". Larger amounts are grouped by まん (man) "10,000", so 20,000 is にまん (niman), not "twenty thousand".

What Learners Are Saying

“Teaching in Osaka and I wanted to connect with my students beyond the classroom. The everyday conversation made my Japanese feel natural, not textbook-y.”

Mia S., 25, English Teacher

“I hop cities every few months and this is the only app that actually prepares me for living somewhere, not just visiting. Tokyo was the real test — passed with flying colors.”

James O., 28, Remote Worker

“I tried five different apps before this one. The roleplay conversations are what finally made things click. I actually remember what I learn now.”
