It appears that even as early as 1952, some people were doing “very well, thank you” despite the suffering going on all around them. Then again, the heroes of Yasuki Chiba’s charming ensemble rom-com Tokyo Sweetheart (東京の恋人, Tokyo no Koibito) are relentlessly cheerful and likely wouldn’t use the word “suffering” to describe themselves, preferring instead to laugh at the foolishness of wealthy men and their petty squabbles while continuing to value what is honest and genuine above greed and insincerity.

At least, there’s a minor irony in the fact that Akazawa (Hisaya Morishige) makes his living selling pachinko balls, a a source of elusive hope that’s brought ruin to millions. His mistress, Konatsu (Murasaki Fujima), exclaims that when you’re doing well a ring or two is nothing, trying to manipulate Akazawa into buying a 500,000 yen diamond from the jewellers’ downstairs. Akazawa can afford to buy it, but he doesn’t really want to because he’s cheap and greedy. Later we’re introduced to a friend of portrait artist Yuki (Setsuko Hara) who does caricatures on the street corner below the office and hangs out with the three shoeshine boys opposite. Harumi (Yoko Sugi), a sex worker, has fallen ill presumably from tuberculosis. They only need 500 yen daily for her living expenses and medicine, but the only way they can hope to come up with it is by getting a large amount of people to part with a small amount of money which they are all willing to do as an act of solidarity. 

In rather farcical turn of events, the jeweller’s has commissioned a fake ring to display in the window for security purposes while they keep the real one in the safe. Konatsu suggests a complex plan to the jewellers of getting Akazawa to buy the diamond but giving him the fake which she will then return and pocket difference. Only Akazawa has the same idea, or rather he only wants to buy the fake one because Konatsu won’t know the difference and he doesn’t think she’s worth the expense of the real one. When he ends up with both rings, Akazawa’s wife, Tsuruko (Nijiko Kiyokawa), makes him give the fake one, which is actually real, to the tea girl, Tama, who wants to sell it, even if it is fake, to help Harumi not only with her illness but to escape sex work. The boys tell her she’s being selfish and naive. If Harumi had any way of escaping sex work she would have done so years ago, there’s no real hope for her now. “A shoe can be repaired,” one of the boys sighs, “but I’m not so sure about her.”

In some ways, it seems as if the genuineness of the ring is unimportant. The two are often mistaken for each other and few can tell the difference. After all, if you like it, what does its supposed authenticity matter and what does that really mean anyway? It does, however, seem to matter to Yuki who later says that she thought the film’s most genuine person, Kurokawa (Toshiro Mifune), was “gaudy and slick” when they first met because he was wearing a tacky tie pin and ring which stand out a mile to her as “fake”. Kurokawa in fact makes the replica jewellery displayed in front windows and dresses in that way as a kind lived brand though he does not necessarily approve of his own occupation. He exceeds expectations when he tracks the gang down in order to pay back some money Yuki had lent him when the conductor couldn’t give him change for his bus fare, as well as treating the shoeshine kids to ice creams and warning off the creepy yakuza type who keeps trying to bother Yuki for dates.

But the contradictions are brought to the fore when Harumi’s health declines and Yuki decides she ought to call the estranged mother to whom Harumi had written a comforting letter stating that she’d married and was living happily in Tokyo, enclosing a photo of herself and Kurokawa one of the shoeshine boys had taken on his toy camera. Yuki wants Kurokawa to pose as the husband so the mother won’t be so upset, only for him to point out that she now asks him adopt a fake persona after taking him to task for confusing people with his “fakes”. Again, this false comfort does seem to bring genuine relief to the mother even if as Kurokawa suspects she’s seen right through their ruse suggesting that authenticity of feeling is the only kind that matters.

Akazawa and his wife, meanwhile, bankrupt themselves trawling the river looking for the lost “genuine” ring sinking to all new depths of absurdity as even Tsuruko dons a diving suit and goes in to look herself. Unfortunately, all they find is a single pachinko ball. There is something quite abrupt about the sudden tonal shift from Harumi’s death bed to the gang laughing away at the foolishness of Akazawa and his wife, the boys convinced that Yuki and Kurokawa are now a couple though they never really enjoy much of a romantic resolution. Kurokawa lives a long way out of town and his home is surrounded by rubble and empty lots, signs of post-war devastation still not fully cleared away though Yuki and the boys, presumably war orphans, remain endlessly cheerful even as the extreme irony of Kurokawa’s rendition of Moon Over Ruined Castle washes over them. They do at least have each other and the strength of their community, living honest and genuine lives every day in contrast to men like Akazawa chasing pointless yet shiny trinkets and falling straight down the plughole themselves.
