More Katakana Diphthongs

In the last lesson, you learned the baseline katakana diphthong characters. Now we’re adding even more diphthongs to bring more new sounds to the language.

More Katakana Combinations to Think About

Remember, katakana is used to cover foreign language sounds in the Japanese language. There are some additional combinations to make these sounds.

Note: notice these are not using only the “I” sound consonants like the baseline combinations.

V (Bw) = VA VI VE VO

The thing to keep in mind is bw is approximating the V sound in English. Some Japanese can get closer to V sound than others. And the one missing V sound, vu, was covered in the last lesson (it’s not a combination).


W sounds are added because the standard kana only covers wa and wo — though you’ll notice katakana now has two wo’s (ウォ and ヲ).


Fu is already a standard sound in Japanese, and you can see it’s used to make the fa, fi,fe, and fo sounds.

Additional Combinations

Study Point

The main takeaway from this lesson is there is a high probability you won’t see these very often. However, the nice thing about them is they’re for approximating foreign language sounds, such as English, that you’re already used to.

Recall Practice

Time to practice! Just like in all lessons, do this as many times as it takes for you to feel like you can confidently select the correct answer without guessing.

This recall covers all the modified characters all together – 25 characters in total, a bit longer than the previous lessons.

Good job! Continue practicing until you can confidently complete this with ease. Use the buttons below to restart the practice (challenge yourself with inverted and challenge mode).

Once this practice feels easy to you it’s time to take a quick break and then move on to the next lesson.
