I just received the following email from Apple:

Based on this I have removed Sudoku Grab from sale in Japan.

Updating Sudoku Grab - Currently, I am revitalizing Sudoku Grab, my first app ever, published in 2009. The plan involves updating the code, upgrading to ARC, simplifying the menu system, accommodating iOS7, and supporting 4-inch display sizes. Future updates may include iCloud syncing features for universal access to puzzles. This endeavor also gives me an excuse to switch to an iPhone5s!
Version 2 of SudokuGrab released - We've updated SudokuGrab with some major enhancements including iCloud syncing for your puzzles and support for iPads. There are a few bugs we're aware of and we're actively working to fix them in the coming weeks, with a new version already submitted to the app store.
25000 copies downloaded! - I'm thrilled to announce that Sudoku Grab has reached 25000 downloads! As a token of gratitude, the app will be available for free until the 25th June. A huge thank you to everyone who has purchased the app and for all the valuable feedback.
Tanks! will soon be removed from the US app store - Well, it's game over for my creation, Tanks!, in the US app store. You won't believe this but Atari's claiming it treads too closely to their copyright. Kinda feels like they think they hold the exclusive rights to all tank-driving games. I'm not buying their claim one bit but, when the game's bringing in less than a buck a day, who can afford legal bills, right?
How does it all work? - In this blog, I explain the process behind my Sudoku Grab app, a solution that uses basic image processing techniques to recognize Sudoku puzzles. This is done by locating the puzzle in an image, turning it back into a square form, segmenting it to find potential numbers, and lastly, recognizing those numbers. This involves simple thresholding techniques, blob extraction algorithm, perspective transform, and a Neural Network for Optical Character Recognition (OCR) to recognize digits from the photograph. I conclude by mentioning the potential for multiple enhancements to this process.
