Depends on your attitude to modelling! Mixing models of Japanese 3'6"
stock and European Std. gauge stock on the same tracks will never be
'accurate' so what difference will a slightly different scale make?

Railway modelling scales in Japan differ a bit from what is common in the
rest of the world. A short list with some characteristics.
N-scale is by far the most popular railway modelling scale in Japan. The
products available vary from cute toys top quality models, both
mass-produced and handmade brass models. Usual scale ratio is 1/150th scale
instead of 1/160th as common in the US or Europe. 1/160thscale is used in
Japan for models of Shinkansen high-speed trains, which have a larger
loading gauge than ordinary japanese trains. Prototype japanese trains run
on a track gauge of 1067 mm (3ft6in) or 1435 mm (4ft 8½in), narrower gauges
used are 762 mm (2ft6in) and 600 mm (2ft). The Japanese have chosen to use
normal 9 mm track for all prototype gauges between 1067 and 1435 mm.
Narrow-gauge lines are not often modelled in N-scale, so it's no surprise
that there's not a lot available 'of the shelf'. You could have a go with
European Z-gauge mechanisms and trackwork.
HO comes next and this is where life becomes a little more complicated. In
Japan there are 3 different HO standards. Most common HO standard is 1:80
scale on 16.5 mm gauge track, also known as #16 scale, but some more
advanced modellers found this unacceptable as the track gauge is too wide
for the 1:80 ratio. So they started a different standard, 1:80 scale on 13
mm track, which is to be handlaid as there is no ready-made track available.
This scale/gauge is called #13 scale. Other modellers adopted the
international 1:87 scale ratio and use a 12 mm track gauge, as per the
European narrow-gauge standards This gauge is known as #12 scale. HO-scale
has only a very small share of the Japanese model market, as homes are very
small by European or US standards, and it is hard to find some room, even
for an N-scale layout. In some towns model train clubs, pubs, restaurants or
hotels offer rental layouts on which you can run your own trains at a
charge. There are also N-scale rental layouts available in some locations.
Other Japanese modelling scales are 1:50 on 20.5 mm track gauge (static
models only) and O-scale tinplate. A few handmade models are available in
1:120 scale, running on 9 mm track. This scale is also used in New Zealand
as it fits the New Zealand trains (small loading gauge, 1067mm, 3ft 6in,
track gauge) very well.

I agree in the general case.
However, I have a MicroAce model of the 2-4-0T which was the first Japanese
steam loco, and its scale is closer to 1:120 than 1:150. Given the narrower
gauge, its actually quite accurate, though looks big alongside circa 1:150
items.

Thanks for your seal of approval Nigel.
