1. Japanese nouns have no gender and number.
Japanese nouns do not have gender, and rarely, number aspects. With most Japanese nouns, number is not an issue. The same word is used for one or more than one.
hon = a book or books
kuruma = a car or cars

2. Verb conjugation is not affected by the gender or number.
The same verb is used no matter what the subject is.
私はビデオをよく見ます。 I watch videos often.
彼はテレビをよく見ます。 He watches TV often.


3 Japanese verbs have only two tenses; the present tense and the past tense. The present tense refers to habitual action or the future. The past tense is used for actions completed in the past. It is also equivalent to the English present perfect or past perfect.
