An interesting day with a better last half — stress wise — heavy traffic with trucks galore , narrow multi lane freeways and a particularly nasty tunnel made the first half a bit testy , after about 50 kms I started to enjoy more rural country with less tight squeeze points . The mirror has been useful.
Kyushu and Honshu are separated by a narrow strait that has a constant stream of shipping moving thru , not unlike the Dardanelles in Turkey. Japanese engineers must just love tunnels , there is a vehicle tunnel a bridge and a pedestrian tunnel . Took me a wee while to actually find the later. Had to enter a building and use a lift to drop down to the tunnel entrance . 700 metres , had to walk it and a surprising number of older Japanese folk seemed to be power walking it.
Was a long day in the saddle , getting lost a little at times in the laberinyth of highways heading north . Started to eventually get on some more quiet rural roads ( a relative term) interested scenery with beautiful houses and gardens in some places. Vegetative growth is rampant and uncontrolled often , but the gardens attached to these homes are testament to careful training and control . A sample pic
