That's strange. Softbank definitely provides UMTS service and it definitely
works for roaming with foreign phones. See, for example, here:

The 3G stuff was originally developed in Japan by NTT, but got
changed a bit in the process of ETSI and ITU standardisation. NTT
had deployed a pre-ITU-standard network that was well-known for not
quite working with some standard 3G phones, though I've not spent
time there for a few years and for all I know they've fixed that
by now (though there's still North America, of course, where the 3G
is standard but runs on non-standard frequencies).
Note that, like the UK, 3G in Japan is only well-deployed in the
cities. Away from there the coverage is all PDC or CDMA, for which
a local phone is definitely needed.
