Hi, did a search and didn't see any posts with this title specific to JAL (saw a post for SQ though!)

I read that the JAL Domestic First-Class window seats are quite nice and that the bulkhead has great legroom. We would be two people traveling together, and we go back and forth between getting window seats and center aisle seats, in general. We are debating between 1AC, 2AC and 1DG for JAL's Domestic First Class. However, we have some preferences / constraints:

1) We like underseat/in-front-of-seat footwell storage space to be able to store a large totebag (14x10x10 or 10x12x8). It's unclear from photos online, but it seems there may not be enough footwell storage that's big enough to accommodate any of these size bags (14x10x10 or 10x12x8) - is that correct? In which case it would seem 1AC would be the better option for more leg room since there wouldn't be any real footwell storage and the totebags would have to go overhead anyway.

2) For the bulkhead seats, is there enough overhead luggage space for 2 standard US size (14x22x8) rollerboards or are the spaces filled with equipment / blankets / etc. (thereby forcing you to put the luggage back by row 2)?

3) Seatguru has seat 1C in yellow due to proximity to the galley (and toilet) - presumably the same issue with seat 1D. Are seats 1C and/or 1D "yellow" in your view?

Thanks much in advance!
