I just received a message from the service that I booked to pick me up at NRT that due to cherry blossom season and a shortage of customs workers that arrival wait times are currently stretching to 4 hours. I have been searching all over the web for information on the current situation but have come up completely empty handed. The airport's website doesn't seem to have any info

Any very recent experiences? I arrive on NH business class from BKK around 15:30 on Sunday
