Candidates for deletion - not "town tramway systems." 

The following are candidates for deletion from this list because they are (were), arguably, not "town tramway systems:"

Akayu, Tokyo-Kanamachi: Labeling these systems as "town tramways" seems far-fetched; see Wakuda.
Nikkō: More of a rural tramway than a "town tramway."
Ichinomiya: More of an electric light railway than a "town tramway."
Takaoka: Admittedly, a borderline case, but on the suburban or electric light railway side of the border.
Kyoto-"Keihan Keishin Line," Never a "town tramway;" certainly not so today.
Osaka-Kobe; Ōita - Beppu: Admittedly borderline cases, but on the suburban / intercity side of the border. 
Karatsu: Suburban/rural in character.
Kitakyūshū - Nōgata: Electric light railway, never a "town tramway," certainly not so today.

Kurume-Mameda  (phonetic transcription of 豆田 remains unverified): This entry needs to be reworked along the lines of Niigata - provided that such a service was in fact operated within Kurume. Neither Wakuda nor Haraguchi establish this.

Saga: Neither Wakuda nor Haraguchi establish that this was a "town tramway," rather than a suburban or rural tramway - or one licensed as a public carrier but in fact serving some military function. The latter might help to explain the curious lack of photographs; Haraguchi presented no photos and Wakuda stated that he had never seen one.
