That means you need a JIS bit to go in a torque driver and a JIS screwdriver will never fit in a torque driver  :o

My experience of JIS screwdrivers is they are usually made by Vessel in Japan and bl**dy expensive but don't  have the tendancy to 'cam-out'  like Philips. The Vessel Megadora version have little grip protrusions ... not so sure how much better that is than the standard Vessel ones and my old ones have square shafts you can put a spanner on while Megadora ones are round with a less useful knurled section on them.

I have a set of Vessel ones I got for my 21st birthday and still going strong .. with square shafts....see picture of same type attached.

Having said all this I have had cross head bits from cheopo sets which have broken off rather than cam-out so who knows what the profile of those are.

Just bought a set of 5 JIS screw bits and a magnetic T-bar on eBay, these will also fit my mini socket set so will see how they go.

Arch stanton:
I am assuming Honda have always used JIS screws.
And Honda issued to their machanics a torque screwdriver.
My friend & former Bill Head mechanic still has one of these in his tool box.

Trigger:
Can't remember Honda ever giving me a Honda torque driver, have a old Britool one in a tool box but, that will not remove a JIS screw from any SOHC oil pumps  ;)
