Hi Todd,

Nice tiger and cub. Hard to tell on my screen but I think your photo shows the mark upside down. Looks to me like a Mt Fugi Arita mark possibly a variant used by one of the Fuagawa group.  Awabi type shape for sea food and has a nice subtle color.

Hi Michael,

Thanks. Yes, I think you are right...upside down 😋 .  Is this the mark you are thinking of below, minus the mountain? Its not just your screen, the mark is difficult to make out exactly. 

Todd,

Sort of looks like the impressed mark for Seigi Kaisha , Mountain Water or Pure Water company. It is really hard with Arita marks they are all so similar. Impressed marks can be especially hard.

It has a peach shape, I like the color too.  I'm going to look up Awabi now.

P.S.  I guess from Awabi information it is more a shell shape than a peach.

Hey Todd, 

I'm going to help you with some advice that will assist you longterm with the items you seem to come across often and ask a lot about:
("Give a man a fish and feed him for a day" vs "teach a man to fish")

In general, this is something that most people are either not going to know off the top of their head usually; and over time, I've found that those who would/do know, are largely unwilling to help.
This is also considering the backlog of other attributes most dealers and specialists have either in their own inventory; or from clients who respect what they do enough to pay them since it's their profession and therefore income, and usually with other large time commitments on hand if they stick exclusively to a smaller niche in a tighter industry. 

So, here's some "trade secrets" that you can reference for free - and assist you valuably in the time to come.. 

It's common to charge about $100-$200 alone per translation attributed, or more; and they're usually outsourced.
I don't know about you, but I'd rather apply myself and make an effort for just 5-10 minutes and save that money for more treasures! 
 
There are a lot of resources here on BidAmount including databases, museum links, archives, and auction catalogues.
Study these, write down what you find out, and keep references on hand - rinse, and repeat. 
As you do this over time, you will come to recognize some similarities in the wares, types, and characters or seals used on many of these items.

Then, when you feel you've "leveled up" a bit: expand your horizons. 
Search the internet and you will find a plentiful amount of collectors or hobby level enthusiast who love sharing/learning; and also who have great databases as well, along with guides for common Japanese characters; especially Kanji.
(Learning this is also going to help you with Kanji script on Chinese works of art to a transferable degree, and being in Thailand you likely come across some great pieces of that nature as well).

These people are the unrecognized and uncredited backbone of the market, and usually they're always happy to discuss pieces since sometimes they see it as a remainder of what was left behind and forgotten: but they're not naive, and can tell when somebody is feigning interest. 
Respect them, show genuine curiosity and desire to grow with your knowledge - you'll even become fast friends with a few. 

Be honest with yourself about if you want to pursue this journey out of passion and sincere curiosity, or if you just want a mark transcribed so you can look up the price on eBay:
There's a site for that already, and it's called AsianArtForums - where you'll notice about 90% of the inquiries go completely unanswered, and imo for good reason.  

Learn to love something, and you will eventually excel at it if you put in enough work - and eventually you'll find a lot of joy and inspiration in doing this to share with others down the line: but you must put in your own effort, and your own work on your own time.

Something I've always loved about the Japanese collecting community is the variety and diversity - usually shared with an appreciation for learning: a lot of what we know today, wasn't known when the market was booming in the final quarter of the 1900s. 
The research and information never grew with the market - and keep in mind, Japan has numerous and plentiful amounts of variance for wares, artisans, multiple generations of styles and makers, kilns, and other nuances. 

It's impossible to know it all; and it's also improbable every question you have will be able to be answered.
I know I still have dozens of things in my "research pile" backlogged for months - and I actually love that, something to do and grow with every time I take a few minutes and research my pile of forgotten treasures.
A lot of what's out there is waiting to still be discovered, connected, and appreciated: you can be a pioneer for finding out new things about topics that many overlooked then, and remain almost completely forgot about today.

So think of this as investing your own time, to harvest the rewards in the future of "narrowing the gap" on identifying pieces you come across: and you may also stumble into what makes this so special along the way. 
The less you have to depend on others, the better of you will be in your pursuit of self education and assistance - but the more you will be able to later share and assist others in doing: it's all a cycle, and it comes full circle if you let it. 

But that's the hard part: you have to let it, and you must make an effort. 

On your piece:
We can probably narrow it down with a little deductive reasoning, and some research. 

Here's some help I can provide to assist you with what I can contribute at the current time. 

It was said that the mark looks a little similar to Fukagawa - or - the later Seijisha/Seiji Gaisha founded by affiliated members in 1879 after the original Koransha group dissolved.
The marks do "blur together" at some point, I agree 100%. 
But with a bit of insight, we could deduce that both of those companies were of Arita origins - and focused exclusively on high fired porcelains.

Arita pieces in general; are porcelains with few exceptions.

Your piece doesn't look like porcelain; so we could probably rule out those options - as they didn't produce things on earthenware such as what yours appears to be. 

Based on the glaze and style; I think it looks like Kyo-yaki.
So is it a studio piece, maybe a production piece? 
These were both common with such a material; so now we narrowed it down a bit more.

Without a tomobako - (which provides a lot of information between the lines) we're left with assuming it is Kyoto produced, or in a location that transported similar earthenware to their production area - and thankfully have some kanji script to reference on the base. 

Sadly, (and sorry), the picture quality is not up to par enough to make out the top characters; the bottom one is "-shu" 
Get a magnifying glass if needed; take out some paper, and write down the formation of the characters. 
Look through some databases, and scroll down until you see a resemblant series of combined marks. 

Write down those options; reference them, and hit the internet to research the possible inscription - keeping in mind the possible area or material of this production when looking through references.

If it's a studio piece, it may be a "one-off" - so see if there are similar styles you come across, or known archival references. 
Sometimes, it's a pen-name for a studio ware instead of the actual name: so look up possible references to artists or facilities that used such after you narrow it down. 

I've typed a lot, and I'm sorry for the length - but this is (once again) to assist you with the many wonderful pieces you seem to come across; as a way to get to know and appreciate the history behind them: and have pride in adding them to your collection, or passion if you wish to part ways with it and instill some context to its eventual new steward.

Hope this helped.

Best,
-JRN

Thank you for the wise words in the post above, JRN. They are also valid for Chinese ceramics (and all other fields of collecting).

Concur with Birgit@shinigami comments ‘wise words’ indeed ...
