It's a nice early piece of Japanese Noritake "Nippon", Nippon being the mark being used on much of the Japanese products made 1891-1921. Nippon has a dedicated group of collectors, but values have crashed for it since the early 1990's. Here is a good link for you.https://www.morimura.co.jp/english/corporate/group.html

Re: Footed porcelain bowl
The first bit of info I’ve found is that it’s a Nippon Maple Leaf mark (I thought it looked like a leaf or a cat face). I’ll add more if I find it but a google search of Nippon Maple Leaf mark is I think the place to start.
“Maple Leaf Nippon; found in green, blue and magenta. Mark
was used by Morimura Gumi as early as 1891 and was used
until 1911.” https://nipponcollectorsclub.com/backstamps/
This page shows that there are also fake Nippon marks https://www.realorrepro.com/article/New-Porcelain-Marked-Nippon

One more link I found interesting https://community.ebay.com/t5/Archive-Pottery-Glass-Porcelain/POTTERY-Is...
Hope this is enough info for you to find out what you have.
