OK, I've got an answer from Jobo. No times given for hand processing.
They explained the complications and difficulties of hand processing E-6 and the benefits of using their processing machines. End of the story

ilford e6(made in Japan)
That doesn't sound very plausible. If it were Ilford, it would actually be labeled Harman and made in the UK. Ilford as such doesn't manufacture anything, so if it were Ilford, it would have to be manufactured by someone else. Whatever's left of the Ilford company operates in Europe, so if they were to sell E6 chemistry (which doesn't fit their business portfolio at all), the likely supplier would be Fuji Hunt..in Belgium.
So Ilford manufactured E6 chemistry, made in Japan? That sounds really odd for several reasons.
FD 6:15 came out too bright for me. Unfortunately I don't have control strips available to confirm this .I agree, the "conversion" between one's tried-and-true Fuji-Hunt times and these new Jobo #9220 times might not be 1:1, especially for manual agitation (on the assumption Jobo really did tweak the formulas to make the kit more rotary-specific).
I recall from the instructions in the Fuji-Hunt kits that Fuji included suggested times for each bath for a few different processing methods (e.g., rotary, manual inversion, sink line, etc.) and that the main differences among the various methods lay in the FD and CD times. For example, the CD time for manual inversion was 6:00, whereas it was only 4:00 for rotary development (presumably because the constant agitation in rotary development constantly refreshes the developer at the film-fluid interface). Looking at these new Jobo kit instructions, which specifically mention that they're for rotary development, I notice the suggested CD time is now... 6:00! One is tempted to ask if Jobo tweaked the CD formula to make it weaker than the CD in the original Fuji-Hunt kits, in which case, someone using manual inversion would presumably need a longer CD time (e.g., 7:00-8:00) in the Jobo chemistry. Interestingly, the Jobo instructions make a point of specifying that the FD time (default is 6:15) may need to be adjusted if one is using a development method other than rotary. The fact that they don't offer the same caveat for the CD bath seems to indicate that they're confident 6:00 will work for any development method, not just rotary.
I normally only run control strips in my Jobo (I always use the Jobo for color film), but my curiosity here is adequately piqued that I might develop a control strip or two using manual inversion just to see how the results compare on the FD 6:15 came out too bright for me. Unfortunately I don't have control strips available to confirm this .
I see what you mean now; the acquisition of the defunct/bankrupt Ilford Imaging by Chugai in 2014. The company is situated in Germany and as far as I know, they put the Ilford brand on a variety of products manufactured by a variety of companies.Actually ilford have sold their color business to Japanese company.Nowaday if you heard any of ilford color news, the product would come from Japan but not Europe

Chugai is indeed a Japanese firm and sure enough, they also manufacture photo chemistry, including something that looks like an E6 kit for small lab use. It's absolutely possible that this chemistry might find its way under different brand names to the market. However, it's not Ilford - it would be Chugai. There's a link to the Ilford name, but Ilford Imaging as such has no manufacturing capability.
Harman Technology, which produces the well-known Ilford photo products, is most definitely not situated in Japan and although theoretically they could manufacture E6 chemistry, I doubt they do this, and certainly not in Japan.
The net result remains that whatever photo chemistry is manufactured in Japan will not be manufactured by any entity with 'Ilford' in its name. It might be Fuji or a selection of other sources capable of manufacturing this chemistry.
Kodak single use E-6 also has this difference(6 mins CD for hand and 4mins for rotary)I agree, the "conversion" between one's tried-and-true Fuji-Hunt times and these new Jobo #9220 times might not be 1:1, especially for manual agitation (on the assumption Jobo really did tweak the formulas to make the kit more rotary-specific).

In a related development, many have probably heard the news (first reported in John Sexton's newsletter, then later echoed on Nico's Photo News) that Photo Systems Inc. (PSI) of Dexter, Michigan has became the official licensee and manufacturer of Kodak photo chemistry. In the personal communication shared by John in his newsletter, PSI's CEO Alan Fischer announced that in addition to making Kodak's suite of black and white chemistry available by the end of this year, they have plans to offer C-41 and E-6 chemistry in 2024. This really caught my attention, as E-6 had, prior to the demise of the 5-liter Fuji-Hunt kits in 2021, constituted the bulk of my home developing.
I reached out to PSI via their website asking specifically about what these C-41 and E-6 kits would look like (i.e., separate bleach and fix? Kodak-branded?), and Alan Fischer was kind enough to respond to me personally. He wrote that PSI intends to release non-blix versions of both C-41 and E-6 processes at full strength (i.e., separate bleach and fix, no starters required) in the first quarter of 2024. The kits will be available in 1-liter and 2.5-liter sizes, as well as in 10-liter replenisher-type configurations (I'm assuming these would require starters). PSI already manufactures a lot of photo chemistry, including color chemistry, so they seem well positioned to quickly get things up and running.
I'm still somewhat curious about the branding. I'm assuming these will be Kodak-branded products, but am wondering if they will be Kodak-specific recipes, a la Flexicolor and the circa-2010 Kodak E-6 chemistry. Regardless of the answers, this is all great news. Given that the continued availability of color positive film is linked to the availability of the chemistry needed to develop it, this could/should be a much-needed shot in the arm for analog color photography.
