This comprehensive lesson by Kensei Sensei breaks down key grammar patterns for making polite requests and prohibitions in Japanese—essential for travelers, language learners, and anyone aiming for natural communication. The video covers frequent conversational structures such as 〜てください (please do), 〜ないで (without doing/don’t do), 〜ないでください (please don’t), 〜なくて (for reasoning or contrast), and 〜ずに (the more formal ‘without doing’).

The video starts by demonstrating how to use 〜てください for polite directives like “Please sit down” or “Please write,” which are foundational in daily life, signage, and instructions throughout Japan. Next, it explores the subtle differences between 〜ないで and 〜なくて, equipping viewers to correctly express contrast, avoidance, or reasoning in natural Japanese. These nuances are especially important for JLPT N5-N3 learners and anyone using textbooks like Genki or Minna no Nihongo.

Illustrated with comparison tables and real-life translations, the lesson also guides you through the formal 〜ずに, commonly found in written and formal contexts. Viewers are encouraged to practice and internalize these patterns not only for conversations but also for travel situations, reading public notices, or following instructions in Japan.

Hosted by Kensei, a Japanese-Canadian educator based in Japan, the channel focuses on deep grammar understanding, cultural notes, and practical communication. This tutorial is perfect for self-learners, exam takers, and travelers who want to sound both polite and fluent on their journey through Japan.
