What is RomajiDesu?

RomajiDesu in Japanese means 'This is Roman Characters (Romaji)'. It's a pun name, because, 'RomajiDesu' is written in Romaji. When you know what RomajiDesu means, you already understand a bit of Japanese. Actually, RomajiDesu includes a English-Japanese dictionary with example sentences, a Kanji dictionary, a Japanese to English/Romaji/Kana translator and a Romaji to Kana converter.

Why RomajiDesu?

There are some opinions against the use of Romaji in practising Japanese. In my opinion, Romaji is still very useful for Japanese beginning learners, especially self-learners because it's less scary. Eventually, you cannot avoid Hiragana, Katakana and Kanji because you need to practise a lot. But then RomajiDesu is still an useful tool for you.
