Ah yes, from the comfort of my desk I too might have thought "This guy can't even find a plug in the country that is virtually the ancestral home of all things electronic." but we flew overnight, wife is a poor sleeper and managed to score a seat-kicking kid behind her (how do their feet even reach in J ?), arrived 6.15 to be hit by a heatwave with temps in the 30's after coming from wintery Melbourne. Strictly no check in at hotel (Century Southern Tower, Shinjuku) till 2pm so off we go to walk around Gyoen Gardens but heat gets to sleepless wife and she faints on a seat. Slowly back to hotel by 13.30 but had to watch 4 reception staff doing virtually nothing for 30 minutes as the lobby filled with other guests in the same predicament (they play strictly by the rules in JP).
Camera needs charging is the first recognition that the new multiplug adaptor the wife bought online doesn't have Aussie input (should have bought the AFF one when I intended to) - housekeeping lady brings American plug, another call and she returns with another the same and declares that is all they have. She smiles triumphantly as she forces a square peg into a round hole and jams our plug into their adaptor - of course it doesn't work! So off to the shops - Takashimaya Dept Store, Tokyu Hands, camera shop etc - 2 1/2 hrs and no result and it's tiresome walking in the heat.
Back to hotel and wife contemplates not being able to capture the happy snaps on camera, not being able to use her hair wand, laptop, charge mobile etc so now the day trip to Hakone the next day is off the itinerary while we contemplate a trip to Akiharbara to get the adaptor, but hey, maybe the good ppl at AFF can save us some time walking around in the heat if I post a question but, my gosh, I'm a tosser for not instinctively knowing where to go in a city I'm not familiar with. Also anticipated (for no good reason I guess) that the English language skills of more Japanese would be more than "Ha-rowww" (hello).
Anyway, thankyou to those who had suggestions. Did find one at Bic Camera store locally and wife's happy, so so am I! And there's only a JP plug in the bathroom austman.
