The short answer is yes – basic Japanese verb conjugation is much simpler than it looks at first glance. That’s because in the polite -ます (masu) form, the verb doesn’t change according to person, the present and future share the same form, and there are just four basic forms to express present/future affirmative, present/future negative, past affirmative and past negative tenses.
What makes basic Japanese conjugation so simple?
One of the first big steps you take when studying Japanese is learning hiragana and katakana. However, by the time you reach basic verb conjugation, especially the polite -ます (masu) form, the structure is quite regular.
Unlike in many languages, the subject does not affect the verb form in Japanese. In other words, it doesn’t matter whether you’re referring to “I”, “you”, “he”, “she”, “we” or “they”, the verb form stays the same.
The subject does not change the verb form
In Japanese, conjugation does not change according to the person you are referring to. That means the same verb form can work for different subjects, and context tells you who is completing the action.
For example, 食べます (tabemasu) can mean “I eat”, “you eat”, “he/she eats”, “we eat” or “they eat”, depending on the context.
Present and future use the same form in Japanese
Another advantage for beginners is that the present and future tenses use the same verb form. You can understand whether the present or future is being used from context, references to time, or the overall situation.
The basic polite form can also be used to express affirmative past and negative past using a very recognizable pattern.
