Getting Namenayo!

After seeing all the pages in this shrine, you're probably
interested in reading Namenayo! yourself. The hardest part about getting
into obscure Japan-exclusive manga like Namenayo! is getting your hands
on a copy of the book. Fortunately, there are a lot of places on the
internet where you can buy each volume.
Reading Digitally
The most accessible way to read Namenayo! is through a digital copy. You can easily find it on digital storefronts like ebooks Japan and Booklive.
Each volume is surprisingly cheap, as they only cost ¥583. (Or around $3.81) After you buy a volume, you can read it on your computer or another device. eBooks Japan offers an app where you can read the books you've bought without having to visit the website. Making the manga reading experience easier than ever!
While this might seem pretty positive, there are a few hurdles you'll have to deal with before you can actually buy a copy of Nameneko Matakichi's Strongest Legend. eBooks Japan is notorious for the fact that you need a Yahoo! Japan account to purchase anything. This is why I recommend Booklive. It allows you to sign up using your email address and you can even earn free points that can be used to buy books.
As these stores are Japanese, you can only buy the manga with yen. Because of this, you'll have to use a service that can convert your currency into yen so that you can buy a volume. If you don't want to go through a lengthy process like this, then there's unfortunately nothing you can do to read Namenayo! digitally.
Reading Physically
If you're unable to buy Namenayo! digitally, your only other option is to get it physically. Since Namenayo! is a manga that's no longer being printed, you can only get second-hand copies of each volume. To make things worse, volumes of the manga are incredibly scarce. You might only be able to find copies of one or two volumes on average, which is a nightmare if you want to have a complete collection.
Despite the odds, it's still possible to buy a volume of Namenayo! through online marketplaces like Mercari and Yahoo! Japan Auctions.
Volumes 1 and 5 are the most common, but the other volumes tend to pop up from time to time. At most, the prices or starting bids usually range from $2.06 to $5.17. If you're lucky, you might come across an entire set of the manga. Since these are sets, they're a bit more expensive to get. The cheapest I've seen was $8.21, but others could range from $12.33 to $42.61.
Even though they might be a bit pricey, the expensive sets are definitely worth the money. The books might be in better condition or could still be sealed. The sealed ones make for great collection pieces and have cool labels like this one that promotes the Hip Hop in Cat City album.
If you just want to read the manga, though, you should probably stick with the regular copies.
When it comes to actually buying or bidding, Buyee is a great service for importing the manga using your currency. There's a service fee of ¥300 ($1.94) for each purchase, but that's normally the only fee you'll have to deal with besides a possible payment fee. Once your volumes arrive at a Buyee warehouse, you can then have them shipped to your address. This process might take a while (especially with auctions), but it works, and it's worth the wait.
