+100 Japanese Twin Boy Names

What are some good Japanese names for twins?

Are you on the hunt for matching Japanese twin boy names? 
I’ve made up a list of cute Japanese names for boys with meanings to help you find the right pair.   

Japanese baby names have become more popular in the west because of their beautiful and unique sounds and powerful meanings. 

They are steeped in culture and history, making them very sought after.   

When considering Japanese twin male names, you can try to find matching pairs that either sound great together or names with meanings that go well together.   
So this list contains both Japanese twin boy names that go together because they sound good and because they have complementary meanings.   

The Japanese language is beautiful and complex and baby names can be just as complex. 

Usually, you’ll notice Japanese baby names are written in kanji (meaning Han character), although some also use hiragana or katakana and others use a mix.  

So depending on what is used, you can have wildly different meanings for names that sound the same.   
Kanji characters are Japanese characters or symbols which represent whole words or names.  Kanji can stand alone or be combined with other Kanji to make new words.   

This is why one name can be spelled in multiple ways and often have varying meanings.

If you find a name you love be sure to explore the various popular Kanji combinations to find the meaning you like.    Since there are literally tens of thousands of Kanji to choose from, I won’t list all the meanings but will try to list the most popular or common ones.   

I became more familiar with Japanese names while teaching English online to children in Japan. It’s a different culture and I just wished to learn more about Japanese people and their customs and ideas.  

One fun tidbit I learned from a mother of my students (who actually had twin boys) was that it was often commonplace for the twins to share a Kanji character as a way of tying siblings together.  
She said in older days this was pretty typical for siblings in general but not as much anymore. 

Many of the names on my list are suggestions from my student’s parents or even a tribute to some of my students as well.

Let’s check out some of the best Japanese boy names, shall we?!

The Best Japanese Twin Boy Names

This list of Japanese names for boys is obviously of Japanese origin and includes both modern and traditional names. Many are popular Japanese baby names that are quite common but I’ve also included some rare and uncommon ones as well.

I’ve actually got an entire list dedicated to beautiful and unique Japanese names for boys (over 450!) in case you want to come up with your own pair of twin boy names that aren’t on this list.

If you’re curious about the top boy names in Japan, check out that list.

They don’t have an official list that’s done by the government as we do here so that’s the closest thing to it.

Aiko & Akira

Aiko –  this cute Japanese boy name means ‘love’ ‘affection’ and the ‘ko’ means child so I would say it means ‘beloved child’ – how sweet is that!

I think this pair of Japanese boy names sound beautiful together if you want names that sound melodic without being matchy. 

Akihiko & Akihiro

we remain in doubt. We want opinion on Yu. In google Yuu is kind and we really liked him. However, I have seen that in other languages ‚Äč‚Äčtranslating its kanji is Yu. However, if I write Yu in Google it shows that it is a Chinese name.

How would foreigner be spelled correctly? Yu or Yuu? sorry for my bad english
