One-step verb -一段動詞 –

japanese conversation grammer learning

The second group of Japanese verbs is called a one-step verb.




If it ends with the sound “iru” or “eru”, it is usually a one-step verb. Here are some commonly used Japanese verbs that look like one-tier, but are actually five-tiered. The one-step verb also follows a simple conjugation pattern that is somewhat similar to the five-step verb. The following is a verb conjugation diagram of Japanese one-step verbs. 

食べる たべる taberu (to eat)  

食べ たべ tabe Base 1 

食べ たべ tabe Base 2 

食べる たべる taberu Base 3 

食べれ たべれ tabere Base 4 

食べよう たべよう tabeyou Base 5 

食べて たべて tabete Base “te” 

食べた たべた tabeta Base “ta” 

Base 1 and Base 2: As you can see, Base 1 and Base 2 are the same. Similar to the Godin verb, you can create a negation by adding -nai (eg tabenai-I don’t eat). This base or root form is also used for the formal form of the verb. 

Bass 3: Bass 3 is the same as the Godin verb. 

Bass 4: Bass 4, however, cannot be used alone like the Godin verb. Used only for “if verbs” by adding -ba. (Example: tabereba-If you eat …) It is not a low command form of a one-step verb. The low command format for one-step verbs is Base1 + ro. 

Bass 5: Bass 5 is the same as the Godin verb. 

Bass “te” and Bass “ta”: The form of the Bass “te” and “ta” for the Ichidan verb is much simpler than the Godin verb. Simply remove the “ru” and add “te” to the base “te” and “ta” to the base “ta”. These have the same function as the Godin verb. 

This is a one-step verb. Take advantage of what you have just learned on a piece of paper. 

いる いる iru to exist (animate), to be somewhere 

見る みる miru to see 

寝る ねる neru to sleep 

着る きる kiru to wear, put on 

出来る できる dekiru can do 

覚える おぼえる oboeru to remember 

Irregular verb 

The last type of verb is an irregular verb, but remember the table below as there are only two in the whole language. The first is to do (do something). Many nouns can be used as verbs simply by adding “do” immediately after them. Probably the most commonly used Japanese verb. The second irregular verb is coming. 

する する suru (to do)  

し し shi Base 1 

し し shi Base 2 

する する suru Base 3 

すれ すれ sure Base 4 

しよう しよう shiyou Base 5 

して して shite Base “te” 

した した shita Base “ta” 

The functionality of these basses is the same as for the Godan verbs, except that bass 4 can only be used as an “if verb”. 

The rude command form is “white”. 

来る くる kuru (to come)  

来 こ ko Base 1 

来 き ki Base 2 

来る くる kuru Base 3 

来れ くれ kure Base 4 

来よう こよう koyou Base 5 

来て きて kite Base “te” 

来た きた kita Base “ta” 

The functionality of these basses is the same as for the Godan verbs, except that bass 4 can only be used as an “if verb”. 

The rude command form is “carp” and should really only be used on animals. 

日本語の動詞の2番目のグループは一段(一段)動詞と呼ばれます。 「iru」または「eru」という音で終わる場合、通常は一段動詞です。一段のように見えるが、実際には五段である、よく使われる日本語の動詞がいくつかここにリストされています。一段動詞も、五段動詞とやや似た単純な活用パターンに従います。以下は、日本語の一段動詞の動詞活用図です。 











ベース4:ベース4は、ただし、ゴダン動詞のように単独で使用することはできません。 -baを追加することにより、「if動詞」にのみ使用されます。 (例:tabereba-食べたら…)一段動詞の低コマンド形式ではありません。一段動詞の低コマンド形式はBase1 +ろ(ro)です。 


ベース「te」とベース「ta」:イチダン動詞のベース「te」と「ta」の形式は、ゴダン動詞よりもはるかに簡単です。 「ru」を外して、ベース「te」に「te」、ベース「ta」に「ta」を追加するだけです。これらは、ゴダン動詞と同じ機能を持っています。 











最後のタイプの動詞は不規則動詞ですが、言語全体で2つしかないので、以下の表を覚えておいてください。 1つ目はする(何かをする)です。多くの名詞は、その直後に「する」を付けるだけで動詞として使用できます。おそらく、日本語の動詞の中で最もよく使われています。 2番目の不規則動詞はくる(来る)です。 





















Now that I know about 30 Japanese verbs and can use them, I will explain what you can do with those verbs. The following table applies to all Japanese verbs unless otherwise noted. 

Base 1   ない Base 1   nai plain form negative (will not verb) 

Base 1   なかった Base 1   nakatta plain form past negative (did not verb) 

Base 2   ます Base 2   masu polite form present/future tense 

Base 2   ました Base 2   mashita polite form past tense 

Base 2   ません Base 2   masen polite form negative (will not verb) 

Base 2   ませんでした Base 2   masen deshita polite form past negative (did not verb) 

Base 2   たい Base 2   tai want to verb (add です (desu) to make it polite) 

Base 3 Base 3 plain form present/future tense 

Base 4   ば Base 4   ba if verb 

Base 4   る Base 4   ru plain form can verb (Godan verbs only) 

(verb now becomes an Ichidan verb) 

Base 4   ます Base 4   masu polite form can verb (can be changed like above) 

Base 5   とする Base 5   to suru try to verb 

Base “te”   欲しい Base “te”   hoshii want someone else to verb 

Base “te” Base “te” plain form command 

Base “te”   下さい Base “te”   kudasai polite form command 

Base “te”   いる Base “te”   iru plain form presently verbing 

Base “te”   います Base “te”   imasu polite form presently verbing (can be changed like above) 

Base “ta” Base “ta” plain form past tense 

Base “ta”   ら Base “ta”   ra if and when I verb (similar to Base 4   ba) 

Base “ta”   りする Base “ta”   ri suru do such things as…

Why Remote Work is Beneficial for Learning Japanese.

Why working from home with a pandemic is useful for learning Japanese. The recent pandemic has forced people all over the world to adopt remote work, and it has become a kind of experiment in the way we work. The forms of communication and collaboration between people are changing every day, and we may never go back to the way things used to be. The advantage of a remote workplace is that this paradigm shift seems to have dramatically improved the ease of learning Japanese. The most obvious change is that communication, which used to take place offline, has moved

Tips for Japanese learners feeling that they’re not making progress

These days there are increasing opportunities for Japanese learners, mainly expatriates relocated in Japan to talk with native Japanese speakers (via online, or in real life). However, even those that have been there for some time often say they tend to be anxious about making “casual conversation” with them. Here’s what can be done about that. But first, is Japanese really difficult? It depends on your mother tongue. Usually, for native speakers of European languages such as English, French or German, which are linguistically very distant, Japanese tends to be more difficult. However, for Korean, Turkish, and Mongolian speakers it

Pot Nabe

Japanese food culture Pot Nabe On cold days, the pot is great for warming your mind and body. Here are some of the most popular varieties in Japan. Gathering around a steaming pot is a classic way to prevent winter blue in Japan. The pot is placed on a portable heat source (usually a gas cartridge stove) on the dining table. When the kelp soup stock and water are boiling, add ingredients such as seafood, meat, tofu, and vegetables. When the pot is boiling, transfer the food cooked with chopsticks to your bowl and add seasonings such as soy sauce,
