Status Updates From Judo Boy

Read this over 50 years ago, and it's stuck in my mind all these years. Have been searching for it for decades, but couldn't remember the title or author. Came across this title and downloaded it from Kindle Unlimited for $0.00 (what a deal). A quick text search of "Amiko Tanabe" (the only words I remembered from the book. My schoolboy crush. LOL) showed this to be just what I was looking for. Color me jazzed.
