You studied Japanese. Then you landed in Japan.
You know the grammar. You freeze when someone speaks fast. You say すみません and still feel off. That gap is not your fault — apps teach drills, not real life.
- “I passed N3 but still sound like a textbook.”
- “Duolingo never explained why my すみません felt wrong at work.”
- “I want to sound polite without sounding robotic.”

Built by someone who hears textbook Japanese every day
I'm Japanese. I built Frensei because learners deserve better than「教科書の日本語」— the stiff phrases that make native speakers wince. Real Japanese is situational, polite, and human.

いただきます
I humbly receive (said before eating)
Itadakimasu expresses gratitude to everyone involved in the meal—farmers, cooks, and dining companions. It is not simply "bon appétit."
お疲れ様
Thanks for your hard work / good job
Acknowledges shared effort and fatigue. Used when leaving work, finishing a task, or greeting someone after their shift.
よろしくお願いします
Please treat me well / I look forward to working with you
Bundles goodwill, cooperation, and a soft request. Context decides whether it means "nice to meet you" or "please handle this."
すみません
Excuse me / I'm sorry / Thank you (light)
Lighter than ごめんなさい and more versatile than 申し訳ございません. The Swiss Army knife of daily Japanese.
すみません vs ごめんなさい
Excuse me / light sorry vs personal apology
すみません = social friction with strangers or light regret. ごめんなさい = personal guilt toward someone you have a relationship with.
ありがとうございます
Thank you (polite)
Polite default in shops, offices, and with strangers. ありがとう alone is for close friends and casual moments.
