1. [+2,164, -111] Because it's better money...

2. [+2,199, -533] Their worth as products are slowly dropping in Korea so they're making what they can in Japan

3. [+1,409, -106] Whatever the agency wants

4. [+1,282, -90] Because they make more there..

5. [+211, -42] SM already has so many artists promoting in Korea already... they probably want to get their rookies going before an SNSD comeback ㅋㅋㅋㅋㅋㅋㅋ

6. [+191, -47] Big Bang's been in Japan for 3 years and articles like this never came out, I guess SNSD is SNSD for a reason

7. [+188, -51] I heard they might comeback in May. I want another concept like 'Gee' personally ㅠㅠㅠ Looking forward to it

8. [+157, -28] They are still preparing a Korean album regardless of Japanese promos

9. [+113, -9] Probably because EXO and Red Velvet are both promoting right now. Before, SM used to space out promotions for each group perfectly but now there's so many overlapping.

10. [+107, -12] Japan's music market is 20 times that of Korea's
