Surely Japanese mains supply, or rather the tools designed for it, are compatible with North American mains? 100V 50/60hz. Shouldn't require any modification more drastic than a plug change!
Most mains supplies aren't exact anyway. Over the years I've seen supply voltages with about +/- 10% of the nominal voltage. With that lovely big inline tranny & rectifier, even if the North American supply is 10% "hot", that big, heavy supply box should smooth it all out beautifully.
Remember that DC battery supply is similarly imprecise. The nominal voltage varies radically across the charge cycle. In a Li-ion battery from 40V+ to maybe 25V or lower as charge diminishes from a nominal 36v battery.
That mains supply unit, as rated on the type plate, is good for a stable supply at about 900w, 36v nominal.

I’ve gotta think that in the case of the charger (if someone didn’t have one already) other than changing plug end as others have mentioned, you just have to contend with the front end of the power supply in the charger.
Reasoning that as long as it can handle a moderate increase in input voltage, and heat sinks can offload any added heat in that section, then the rectifiers etc. are still going to produce the same dc voltage (regardless of plug voltage) needed for the rest of the components.
I've read online that Japanese corded heating appliances, induction elements in rice cookers etc, will overheat on 120v. But I doubt a well engineered power supply would react the same, to any great degree.

I was at the Metabo HPT release event. The tools were really impressive. The battery uses 21700 cells. Most tools available now in NA - online, Menards customer service phone number, select Lowe's Cordless table saw is based off the corded Hitachi out now. Will be available early 2019. The show stopper was the Japanese built 7 1/4" miter saw. This will be available late 2019 as it's waiting on UL certification and other such details. Pricing will be around $1000. It's on another level of precision and made the 10" miter they are releasing feel like a toy. That 7 1/4" mitre saw is the one I am waiting on. With some luck it will surface sooner in Europe - they usually do. Nice to hear about your impressions and good to get some confirmation on what to expect.

Just to check that we're on the same wavelength, are we talking of Hitachi Koki/Hikoki merchandise here or Metabo?
It's probably about time that Metabo updates its cordless SCMC, but I'd personally be loath to purchase anything smaller than the existing 216mm/8 1/2" model. Still, having the new 10.0AH batteries available will be a VERY good thing with this type of semi-stationary tool.

I'm thinking of upgrading my kss40 batteries from the old 5.2 to the 5.5hd. Will this make a significant difference in power / runtime? Also how much better are the new design 5.5 with 21700 better over the older 5.5 with 20700 cells? I prefer the older design and they're slightly cheaper. The 8ah are out of budget unfortunately. Any help greatly appreciated.

Marginal improvements in both. Unless you're using high-drain devices I sincerely doubt there will be any discernable difference.
Li-HD batteries will provide higher current flow both inwards & outward for Saws, Grinders etc. to perform more efficiently. In smaller appliances, drills, rattlers & the like, any benefits are incrementally less.
I'd always regarded the 5.5 AH Li-HD batteries to be a puzzling choice. All the weight, bulk & overall mass of the more powerful alternatives without any perceptible benefits. For smaller hand-held tools, I much prefer the smaller size,weight & overall ergonomic balance of the 4.0 AH Li-HDs. For my ageing hands, they just seem to be a far superior "fit" on my drills, rattler etc. For my saws, grinders, floodlight, radio etc. I much prefer the power & runtime of the largest Li_HDs.
Given that there's now 10.0 AH double-row batteries available, I suspect that it's merely a matter of clearing unsold stock for the single-row 4.0 AH Li-HDs to be replaced by more powerful but similar sized 5.0 AH versions too.

The 5,5ah's can be had for a good price at the moment. You get more power (torque) from the 5,5's than the 4,0's when using the KSS40. It's not just run time - I don't why, you just do. I just picked up 4x 5,5's for less than the price of 2x 8,0's - makes it a very good deal.
