One day in Japan

Hi all,

I’ll be in Japan in March and will have maybe one free day to do some
birding.

I will probably have the option of spending that day in either Kyoto or
Osaka.

Does anyone have any tips about which would be the better option? I have
seen some info on the Nanko Bird sanctuary in Osaka harbour that looks good,
and the timing (late March) would be good for migrant waders, though I will
only have binos, not a telescope.

Any tips?

Regards,

Paul.
