Store or Ship in NRT?
 

So I'm doing a mega vacation in March. 9 Days in Hawaii, 9 days in Japan (via NRT) and 5 days in Singapore. Last year when I was in Japan I loaded up on ceramics, sake and whiskey (It's Suntory time!) At any rate, I don't want to haul all my loot from Japan to Singapore and Back. It sounds like a hassle in customs in SIN and a lot to carry.

On the way back from SIN I'll be in NRT for about an 1:45hr. I'll be flying NW so I'm not sure the best route to take here. If it was JL I'm pretty sure I could drop the packages off with JL's Takuhaibin service and everything would just happen. Is there a place air-side in terminal 1 to store something for 5 days? Or is there a good shipping service I could use? I don't think I can check bags that early.

1.45hr is pretty tight to go through immigration, get the bag and recheck it. I can't remember any airside baggage check at NRT. I have checked a bag in the middle of two flights years ago but I don't know if you can do this today.

There is an airside baggage check in Changi T2 and I will use it this week. But it is before immigration so you have to think through how to arrange your items as you can't carry much liquid in carryon.

Correct me if I'm wrong. If I'm reading the other liquid thread correct no liquids allowed through any security checkpoint? Last year when I was on a JL flight they only did the liquid check right before you went down to the departure gate. That's changed right?

I looked at the NRT webpage, it seems there is a storage service on the 4th floor, but it's not at all clear if it's airside or landside. It's been about 7 years since I've been in Terminal 1. I remember going through metal detectors/x-ray when I got off the plane last time and being herded into one of NW's satelites, is there any security between the satellites? I.e. Worse comes to worse can I hit duty free with out having to do immigration/security?
