Are you aware that you're responding to almost a year old posts?
Anyway,
>>37 is me. There's no proper pronunciations for those. Also, if you're really good at Japanese, you'd realize how difficult to pronounce くあ as its spelling suggests. You'd automatically insert very slight "w" between く and あ. If you're Japanese, you're unconsciously doing this.
Try saying アクアリウム (aquarium) in Japanese. If your Japanese fluency is native or near-native, it falls somewhere between アクワリーム and アクアリウム. Another good example is チャンピオン. You'd sound like チャンピヨン if your pronunciation is perfect because you automatically insert slight "y" after ピ. This "y" is more noticeable than the "w" between く and あ though.
