These are TakaraTomy toys (and maybe some significant licensed items) currently known from official sources, scheduled for release in JUNE in Japan (as well as in Asia, as most Japanese Transformers toys are also released through Hasbro Hong Kong).

These monthly lists will be archived on the 2022 Transformers Checklist if you need to refer to these listings later (if anything is found out later, because these monthly lists won't be updated after their month ends).
Some recent listings for reference...
MAY 2022 listing
APR 2022 listing

Dates and details can change at any time - Approximate yen prices listed are just a rough guide to their retail price in Japan.
Links were active at the time they were first added and are only there for reference/proof of details - I do NOT endorse or promote any of those businesses.
(posting corrections or additions are greatly appreciated)

Monthly listings are done after the first week of the month, as that is when the TakaraTomyMall site is updated each month.
