I'm scheduled to fly in to FUK at 8pm on Saturday because I couldn't find an award seat to KIX like I'd originally wanted. I see that the last Shinkansen that goes to Shin-Osaka leaves at 9:09PM from Hakata station. While it looks like a fairly short subway ride, I'm not sure what the immigration line is like at FUK since there doesn't seem to be automated gates there like at KIX. Does anyone have experiences going through on a weekend? Should I expect to make it (so I'd book online in advance) or is it too tight to try to make (in which case I'd go for the 9:52PM Sakura to Hiroshima, stay the night and use one of my remaining Seishun 18 days to go the rest of the way home the next morning)?
