Previous answer is
Kiinzougan Hashiba Okayama Chuunagon Hidenobu Shoji nari/Namioyogi

Special feature : Kanemitsu is well seen during the Nanbokucho period to late Muromachi period. He was born as the son of Kagemitsu.
It is unknown which Kanemitsu it is as there are many same name sword smiths at that time. This blade, however, shows very nice antiqueness.
It is called Namioyogi(swimming in the wave) as the engraved dragon looks like it is swimming　in the
sea wave.
