Since your voicebank isn't in hiragana, you won't be able to use OREMO's oto generator. To use Moresampler's generator, you'll need to separate the syllables with underscores instead of hyphens. Select everything, right click, and choose "rename". Find "-" and replace with "_".

Here's the latest version of moresampler.

To put a voicebank in moresampler for otoing, you'll need to use this command in Terminal.
Code:
export LC_ALL=ja_JP.UTF-8 wine path/to/moresampler.exe path/to/voicebank
Select Japanese romaji.
Yes to VCV.
No to CVVC.
Hiragana only.
Yes, rename duplicates.
Add the appropriate suffix (or none if you're not using one)
Moresampler will then start analyzing the bank and generating an OTO.ini file. If you have any non-standard extra samples it may not be able to read them.
.... Also, it seems like you're missing the vowel-only strings ^^;;
