It’s a strange feeling to be in the open sea. In my opinion, only 4 or 5 hours were truly difficult out of the 50 hour round trip voyage. Others have different experiences, even on the same boat.
Leaving the metropolis produces feeling of excitement, and some trepidation about a 25 hour boat trip. At least we were in a 4 person room with a table, chairs bolted to the floor, and bunk beds.
I love how the passengers share the Ogasawara Maru with a large load of cargo packed in containers. These giant gears operated by a senior citizen control such exact placement.
