Fun* fact: the UK Embassy in Tokyo has negative imputed rent because we rent it from the imperial household for one chrysanthemum a year but if we give it up we have to restore it to it's original state as part of the C19th imperial gardens, which would cost millions * For a given definition of fun

That is fantastic! Where I can I find that in the stats?

...is there a ceremony where once a year then British ambassador has to deliver a Chrysanthemum to the Imperial Household Agency to pay the rent?

Prob saved it from being sold off like many others.

Oh, nice! And chrysanthemums are so much cooler as nominal rent than peppercorns.
