I'm sorry, but without more information about the book, it may be difficult to identify the specific publication you are looking for. However, I can suggest a few resources that may be helpful in your search:

1. Check your browsing history - If you searched for the book online, you may be able to find it in your browsing history.

2. Check your email - If you ordered the book online, you may have received an email confirmation with the title and author.

3. Search online bookstores - Try searching for "Japanese philosophy short stories" or "Japanese philosophy anthology" on online bookstores like Amazon or Barnes & Noble.

4. Ask for help on social media - You can try asking for help on social media platforms like Twitter or Facebook. Someone may be able to recognize the book based on your description.

I hope these suggestions are helpful in your search for the book you are looking for!
