Kiwis adopting the number 39 to say thanks in Japan

In Japan, there's a code word for "thank you" - it's the number 39, which in Japanese is "san Kyu".

But it's just one way Kiwis at a pop-up market in Japan are showing their gratitude to their Japanese hosts.

There's also a kūaha specially carved in New Zealand to be given as a gift to the Japanese. The design of the door is to resemble what is found at Japanese shrines. The meaning behind a two-way door is to say 'thank you for having us, you're welcome at our place too'.

Former All Blacks captain Richie McCaw - fresh from his starring role in the Rugby World Cup opening ceremony - was also at the market to share out lamb chops, with an apron displaying the number 39 on it.

McCaw says he is looking forward to watching a World cup match from the sidelines for the first time since 1999.

"It is quite nice to be not with the tension and wondering what is going to happen. I'm quite excited about watching, to be honest."

Two of New Zealand's best-known brands, the Prime Minister and the All Blacks, also met on Friday night. 

Sonny Bill Williams shared an image of him towering over Jacinda Ardern on Instagram, cheekily writing: "Even better having a yarn with you about having more children".

That received a worried response from Ardern's partner, Clarke Gayford, who replied to the post with: "Ummmmmmmm".

Ardern told media Williams was trying to encourage the pair to expand their family, while she was just trying to encourage him "to win the game".

For all the Kiwi fans flooding into Tokyo, a decent win over the Springboks on Saturday night might be thanks enough.
