If food is at the top of your agenda on trip to Jpn, then you guys in Singapore don't even need to go to Jpn!
Saw lots of Japanese things in Singapore that I wouldn't be able to get anywhere near my hometown in Jpn. Certainly far more than what you could find in LA.
Can't believe you guys have Dosanko Plaza (there's one in Liang Court) and my favorite ramen place Ajisai which is a small ramen chain that only exists in Hokkaido in Jpn.
