Well, 9 months have passed and I am now a resident of Rappungi, Minat-uh-oh
To date, I have:
- filed 0 CC applications (it's been 2.5 weeks, but I guess I must be a slacker

)
- opened an account with Shinsei (whom automatically gave me Shinsei Gold, probably because of my company)
Holding onto my AMEX Plat and SPG cards for now.
If I manage to get an AA card here then I will probably kill the Plat card, since I always fly J and will get lounge access anyway. Would be nice to have an AA Suica card but it doesn't look like such a thing exists. This thread has me thinking about switching to Delta:

Pity that none of the major unlocked flagship devices can use Mobile Suica (including the Nexus 5 and the iPhone)
