On December 18th, 2018 the troutnews website listed two Nissin rods: the 宇崎日新：レベルラインのテンカラ竿 [Nissin level line tenkara rod, and the 宇崎日新：『TENKARA MINI』のテンカラ竿. 25cm (9.8in) collapsed length with 18 sections or joints ( １８継数(本).
Both were posted as new products on the same day, Dec. 18th, on the Nissin website.
The Nissin Ramon [宇崎日新：テンカラ 羅門 （ラモン） 7：3] also has the new tag on it. But I think it was released Oct. 2017. However, I could not verify that date.
Otherwise the only new tenkara products I have recently found are:
New kebari set on the Daiwa website. Actually it shows release date of Feb 2019. [2019.02 デビュー ].
And the TUSA tenugui
Twice in the past I have ordered items from the Oni-shop, Twice included with the items I ordered was a piece of beautiful pattern fabric, about 13.5 x 35 in (34 x 90 cm). I wasn’t sure what they were. I assumed they were just kind of a courtesy gift. Perhaps a bit of fabric left over from making a rod bag. Now I know what they were, a tenugui.
Tenugui ( 手拭 / てぬぐい) are kind of mini version of a furosshiki cloth. With many similar uses.
If you are not familiar with Furoshiki (風呂敷 / ふろしき) . It is cloth folding, basically cloth version of what Origami (折り紙 / おりがみ) is for paper.
