Id please on this yunomi tea bowl, NY OR OJ OR TJ

there is a mark at the base can't really see the first letter clearly maybe NJ OR OJ OR TJ but the last letter is definatly J

please i need help with this tea bowl.... studiopot and tenpot do you guys know who this maker is? can't make out the first letter still trying to make out the first letter any clue would help please

can anyone help me out with the tea bowl please ? i need help here :)

I don't really know but this might be a glaze/clay body test piece and the letters are the potter's code rather than their mark.

My thinking is that the piece is well thrown and the glazes are complex but the mark doesn't look like that a potter usually uses on their finished work.

thanks studiopot..... i will see if i can get the first letter or perhaps i will do more research on this yunomi bowl cup? this is yunomi tea bowl right?

The foot is too good for a student , Chawan = teabowl , Unomi= tea cup , I never understand the fascination with british pots being called eastern names , a tea bowl is a tea bowl imo.

the size is :
height is 9cm
diameter is 10cm
