Naniwa Gouken Kagayaki 400 Grit Sharpening StoneThe Naniwa Gouken line represent a new product offering philosophy from Naniwa, one of the most reputable sharpening stone manufacturers.

The Naniwa Gouken line represent a new product offering philosophy from Naniwa, one of the most reputable sharpening stone manufacturers.

For as long as I could remember, the Naniwa Chosera line represents the holy-grail of sharpening stones for kitchen knives: very fast cutting power, slow dishing and most importantly offering a very very gentle sharpening feedback that was not seen in other stones. The stone is huge in size (25mm thick, with the 10K over 30mm), and is mounted on a traditional base, and there is a free HUGE Nagura (cleaning stone) comes with the package

(The classic Naniwa Chosera is too big to ship)

If you ask me, what is the problem with the Chosera line? Well the single biggest problem for us, the vendors, is that the stone is simply too big to ship: at 210x70x25mm, the stone is too heavy and to be honest, even in commercially environment like the store, we don’t wear out a Chosera that quick, for an average user it is even less likely to wear one out in a reasonable time. The included nargura doesn’t help either as it contribute to a lot of weight with virtually no use at all (most of us use diamond plates or natural naguras anyway).

At over 2KG in shipping weight, the cost of international shipping becomes prohibitive. If we want to make sure the package lands safely (a cracked stone for an international order is a DISASTER!), a lot of padding must be added, resulting in the volumetric weight sometimes exceeding 3KG.

Plus, so many customers asked the question of “Do you offer the Chosera without base?”

 

The Gouken

To adjust the above-mentioned problems, the Gouken line was introduced. Currently there are two sub-labels under the Gouken branding. The Arata and Kagayaki.

 

The Kagayaki

 

The Kagayaki is very budget friendly. My experience with the Kagayaki is also very good. Based on the popular “Naniwa Super Stone”, the Kagayaki is making it slightly harder therefore less dishing, at 10mm thick, it is very easy to carry around and a standard carrying box can fit two Kagayaki stones. I much prefer that Kagayaki over the similar-sized Shapton Glass Stone because:

1. Overall both the Shpton Glass and the Naniwa Kagayaki perform similarly, the Kagayaki has a better feedback.

2. They are the same in terms of size, however the Glass Stone has a merely 5mm of abrasive (the rest is the GLASS). You keep the stone flat by lapping it, not by having a glass at the back.

3. The Kagayaki is cheaper compared to the Glass Stone, and taking the abrasive thickness into account, the Kagayaki offers a much better value.

Easy and simple: Exact Step-by-Step Guide to Reloading Your Balance
Reload type: One Time Reload
I found reloading my Amazon gift card balance much easier than expected. The process was simple and took about 5 minutes at most. Here are the exact steps to do it: ​Login: In the Amazon app or on Amazon.com, log in to your account. ​ Menu: Tap the 3 lines on the bottom right corner of your screen (next to Rufus, Amazon's AI). ​ Find Category: In the section highlighted "Shop by category," tap on Gifting & Registry (3rd option down in that section) and a drop-down menu will appear. ​ Select Gift Cards: On the drop-down menu, tap Gift Cards (first option). ​ Choose Your Action: "The Gift Card Shop" will appear. There you will have three options: "Redeem a gift card," "View your balance," and "Reload." ​ Start Reload: To add funds, tap Reload. ​ Select Type: Scroll down to "Add funds directly to your Amazon Gift Card balance" and tap which reload type you want (one-time, low balance auto-reload, or scheduled auto-reload). ​ Enter Amount: Choose your reload amount. The default is $25, but you can type in your own amount as well (the minimum amount is $5.00). ​ Finish: Tap the orange "Buy Now" tab. ***I used the Amazon app using the u i OneUI version 8.0 these Amazon app on Android version 16 (Baklava) on a Samsung Galaxy S25 Ultra. Others may have a slight variation of the menu setup on the Amazon app.***

Easy way to add balance
Reload type: One Time Reload
Reloading my Amazon gift card balance has been easy and convenient. I like using it when I want to keep a little money set aside for Amazon orders or make checkout quicker without thinking about which card I want to use. The process is straightforward, the balance shows up fast, and it has been reliable every time I have used it. It is also helpful for budgeting because I can add a set amount and then use that balance for regular purchases. Nothing complicated about it, which is exactly why I like it.

Monthly reload for Subscribe & Save Orders
Reload type: One Time Reload
Not a glamorous review, but a genuinely useful tip for Subscribe & Save users. I reload about $100 to my gift card balance once a month, a week or two before my S&S order processes. Amazon pulls each Subscribe & Save item as a separate transaction, which means 10+ individual charges hitting your bank account on before or on ship day. A headache for budgeting and a minor anxiety trigger if you're watching your account for unauthorized activity. Loading the balance first consolidates everything into one clean transaction. Your S&S order then pulls from the gift card balance rather than your card directly, and your bank statement stays tidy. The side benefit is built-in budget discipline. I set about $100 as my monthly Amazon ceiling - if my cart runs over, something gets pushed to next month. It's a simple system that keeps spending intentional without any extra effort. If you're a regular S&S user who wants cleaner finances and less ""wait, who charged this and what was that charge?"" moments, this is worth making a habit.
