と思う — "I think"
To say "I think... (an idea)," attach 「と思う」 to the plain form. But learners often get tripped up by the plain form of nouns and na-adjectives—noun + だ / na-adjective + だ—and mistakenly add だ when connecting i-adjectives and verbs to 「と思う」 as well.
Tomoyoshi Sensei gives 4 example sentences—can you tell which are grammatically correct and which are wrong? In 3 minutes, he focuses on common mistakes with 「と思う」 and repeatedly demonstrates the correct usage with short examples.
だから dakara (therefore / so)
Japanese conversations often include 「だから」(dakara), so some learners habitually use it whenever stating a reason—but not every sentence can take it directly.
This time Tomoyoshi Sensei gives 4 example sentences. Can you tell which are correct, which are wrong, and where the mistakes are? With clear examples, he explains the correct usage of 「だから」(dakara).
「の」 is probably the hiragana character Chinese-speaking learners see most often—even before studying Japanese, it shows up in shop names and ads. But many of those ads misuse it, treating 「の」 as equal to Chinese "的," which leads to wrong assumptions. Tomoyoshi Sensei explains Japanese 「の」 with simple, direct teaching and clear examples, then gives three sentences—only one is correct. Can you spot it?
Happy? Joyful? Enjoyable? Interesting? Chinese has many words for positive feelings—and so does Japanese. When you first learned adjectives, did you mix up 「うれしい(ureshii)」, 「たのしい(tanoshii)」, and 「おもしろい(omoshiroi)」? Tomoyoshi Sensei explains the differences simply and directly.
Some Japanese words Chinese speakers "know" from ads—like 「放題」 or 「の」—have had their meaning and usage distorted by overuse. Shouting 「一番(ICHIBAN)! 一番(ICHIBAN)!」 alone can leave Japanese people completely confused!
So what does 「一番(ICHIBAN)」 really mean, and how do you use it? Tomoyoshi Sensei explains with lively delivery. This 3-Minute Japanese Classroom series introduces everyday Japanese with short lessons and fun performances.
When you started Japanese, have you misused any of these verbs?
友達を見る？本を見る？薬を食べる？ホテルに住む？
In Cantonese we say "go see a friend," "look at a book," "eat medicine," and "live in a hotel"—but using those patterns directly in Japanese is wrong! Let's watch Tomoyoshi Sensei's lively explanation together.
