Ikou Benkyou vs Duolingo for learning Japanese
Pick Duolingo for a free, light daily habit, especially if you're dabbling in more than one language. Pick Ikou Benkyou if Japanese is the goal: a voiced story that takes you from your first hiragana to JLPT N5 grammar, with arcade games to practise and an exam for every lesson. Both are free to start, so you can try them side by side.

Questions
Is Duolingo enough to learn Japanese?
It's a good start for kana and everyday phrases, and it's free. If you want grammar explained step by step up to JLPT N5, with every line voiced and an exam that checks each lesson stuck, Ikou Benkyou is built for exactly that.
Can I use Ikou Benkyou and Duolingo together?
Yes. Plenty of learners keep a Duolingo streak for the habit and use Ikou Benkyou for the path through grammar. Ikou's first six lessons are free, so trying both costs nothing.
Which is cheaper?
Duolingo's Japanese course is free with ads and an Energy limit, and its Super plan's price depends on your region and device. Ikou Benkyou's first six lessons are free, and the pass is US$11.99 a month or US$79.99 a year for the whole line.
Does Ikou Benkyou use romaji?
Only if you want it. Over any sentence you can show furigana, romaji or nothing, and kana practice lets you type in romaji. Exams take the furigana away.
Ride the first six stops free.
The intro, Hiragana 1 to 4 and Greetings are free for good, with their audio and every game. When you want the rest of the line, the pass is $11.99 a month.
