The Grandmaster Puzzles blog had a recent set of "Japanese sums" puzzles, and the mechanics of those puzzles gave me the idea for a Sudoku. It's not too hard, so I hope you enjoy!
The Sudoku grid below follows normal Sudoku rules. The clues on the outside of the grid are the "Japanese sums" for the odd digits in the rows/columns; each number in a clue is the sum of a complete contiguous run of odd digits. These group sums are presented in order (top-to-bottom, or left-to-right, as appropriate), and there must be at least one even digit between each such group. Question marks indicate the existence of a group, but do not indicate its sum; an asterisk represents an unindicated number of groups. All groups of consecutive odd digits in each clued row/column are represented.
To get the checkmark, please include the main logical details of your solution!
