Am smiling at the thought of the poster who has been to Tokyo three times and has seen “everything” it has to offer. I live half the year in Tokyo and am still exploring that huge complex city. But the subway is easy to use, don’t worry about that. Five days is not actually that long. Many visitors do prefer Kyoto - the ancient capital. I do not as I OD easily on temples and shrines. Defintely shinkansen is the way to get there though - sit on the right hand side for close up view of Fujisan. Disneyland is popular spot for young adults - a place to go on dates, a wedding venue, -your ‘kids’ will not be out of place. How do you handle heat/ humidity? Kyoto, which sits in a valley, is particularly bad in summer. What are your interests? Art, design, architecture, technology, history, theatre, gardens, food, fashion…Japan offers inspiration on many levels. There are ‘guide’ services which are actually very reasonably priced ‘international friendship’ initiatives, allowing the guides oppotunity to practise their English and aimed at ’ non tourist’ destinations. As a resident with fair language ability, I have never used them but have read good things about, eg, the night tour of Golden Gai, alley of tiny bars in Shinjuku.
