I've learned loads from reading all the posts but have a few questions I haven't seen answered yet. My family of 4 will be in Japan in late May 2019 for ten days and I was wondering:
We will be taking the Shinkansen from Tokyo to Kyoto and back and will not be reserving seats, are there times that are busy that we should avoid? I believe we will travel to Kyoto on Saturday and back on Tuesday.
I think my kids (16 and 11) will enjoy Odaiba and we can spend half a day there, is it better to visit at day or night?
I saw in some older posts recommendations for carrying cash (and saw about only certain ATMs to use as I'm from USA), and some people recommending MC or Visa and some Amex. Is this still the case today? I'll pay our hotels with credit and prepay tours and things but for restaurants, museum entry, shopping, should I rely mostly on cash?
How easy is it to use the subway, are there english translations or do I need to make notes of how many stations I go through before I reach my stop?
Thanks in advance for any and all help!
