Since I started my study leave I have twice visited Japan, to work with colleagues at Meiji University in Tokyo, and with other colleagues of theirs from around Japan and beyond. They have also visited Reading.
In many ways Tokyo is like other big noisy cities. The skyline show how much more crowded it is than most.
Linguistically things are very challenging as I don’t understand the character set or the words. Fortunately most of the train signs are also in English, and my trusty phrase book helps.
