レンタルロボット

I listened to the audiobook version of this.

Language Learning

This is definitely the easiest children's audiobook I've listened to so far. The language is pretty simple, the narrator speaks slowly, and there are much longer pauses between phrases than other audiobooks I've listened to. This should be a good candidate for a first audiobook.

Entertainment

I found the story to be entertaining enough for such a short children's novel, and it surprised me a couple of times.

In this cute children's book, single-child けんた one day finds a robot rental shop, and decides to rent a little brother robot. From there he learns what it means to be a big brother, and how his family life changes because of it.

I listened to the audiobook for this, so I can't comment on kanji or hiragana, unfortunately. The language was very simple, though, with lots of short sentences and everyday concepts.
