Shogakukan Asia Detective Conan English manga thus far! (Also an image from Volume 1 showing the names switched back to normal on the Detective Agency and in name boxes.)
The volumes use Viz’s English translation but then also switches all names back to their original Japanese. These volumes are a bit unusual however as Shogakukan Asia is purposely printing volumes out of order. That said, each volume is named for a main case found in that particular book. To avoid problems involving cliffhangers, many volumes contain chapters found in the next volume. (So all volumes contain the complete version of a case.) Thankfully the back of each volume explains which numbered volumes the cases came from!
I purchased mine from Kinokuniya Singapore’s website. The easiest way to find the volumes in their search is to search via ISBN number. You can find these ISBN numbers either via Shogakukan Asia’s website or using our handy Shogakukan Asia English manga page on the DCW Wiki!
The most recent volumes I purchased shipped very quickly, however, I should note that the shipping costs an arm and a leg. D: If you were to purchase just one volume, it’s $7.50 (American dollars) for the book but $14 for the shipping!
So that said, this most recent shipment of 5 volumes cost me about $90. >_’ BUT that’s alright with me, cause hey, Detective Conan with the correct names!
