Useful tool to learn Kanji
Kanji is the hardest topic to learn japanese. Fortunately using this DS program we can learn the idioms, pronunciations and some samples in which the kanji is used. The down side is english description is very minimum provided here. So, you still have to equip yourself with japanese-english dictionary. Some words or kanjis here are also equipped with audio pronunciation. There is also alphanumeric input interface to type English word to find their japanese counterpart, which is only useful to japanese people I believe. I hope one day Kanji Sonomama series will come with english translation, so it will make non japanese user to learn the language easier.

Good dictionary at reasonable price
It serves well as a cheap Japanese dictionary.

Very Satisfied
I am very surprised at how much this dictionary can do and I would recommend it to anyone who wishes to further their studies in Japanese.

No title
So so so so helpful!!
I'm really glad I bought this.
Makes study so much easier :D

Worth whatever you pay for it!
I know that there are already a lot of reviews of this product but I think it deserves another one.
I am studying Japanese at a Japanese university at the moment on an exchange prgram from an English University and I use this product everyday.
I'm going to look at the strong and weak points in comparison to a standard electronic dictionary.
Strong points:
*Price (you will pay a lot more for an electronic dictionary with the function of a touch screen to input unknown kanji)
*The ability to enter unknown kanji (there is also a drop-down menu of kanji with the same number of strokes/radicals etc so you can find the kanji even if you enter it incorrectly)
*The fact that there is an English-Japanese and a Japanese-Japanese dictionary on this - as you progress with your studies you will increasingly come across terms that cannot be translated. However this dictionary provides an explanation in simple Japanese.
*The Genius dictionary is also well-respected and has let me down on very few occasions.
*The DS has a lot of dedicated kanji-learning software so buying this dictionary plus a DS will be cheaper than an electronic dictionary, plus give you the freedom to try these other products. (such as Kanken, etc)
*Pre-loaded quizzes on kanji for countries etc - they are very difficult but useful!
*Portable flashcard program allowing you to enter your own list for learning although it is limited to quite a small number.
*A lot of example sentences which help clarify the different usages of a word - very useful to save one from embarrassing mistakes!
*The ability to change the size of the kanji on screen to help with writing it.

Weak points:
*Doesn't contain any kanji for Japanese names. However, you can look up each individual kanji in the names and combine them to get the reading.
*Cannot use the other kanji learning software or play games in japanese at the same time (like you could with a separate dictionary)I have taken to writing down any unfamiliar kanji and checking them in this dictionary afterwards.
*After entering a word in English and being given the Japanese translation, the Japanese translation appears in kanji only so you must copy those kanji onto the touch screen to find out the reading.

Overall i think this software is worth everything I paid for it and more as it has become my constant companion. So far, as a result of me using it in my Japanese university, five other exchange students and Japanese students studying English hav purchased this software and all recommend it highly.
Definitely a very competitive alternative for anyone looking for an electronic dictinary but without spending so much for an applicance with only one use.
I will be looking forward to further software from this company and looking for similar products in other languages!
