Reki Reinantha spent the last six years behind the sushi counter at Lucas Group’s Japanese restaurant Kisume. There, Reinantha, originally from Indonesia, honed his Japanese culinary skills and developed a love for the country’s dining culture.

Since leaving Kisume in October 2023, Reinantha has started izakaya pop-up Rei, kicking off with a December residency at Fitzroy’s Bonny. Then, in February, he launched Sachi, a casual pop-up concept specialising in chirashi bowls and nigiri sushi, at Kantaro Okada’s tiny sake bar, Leonie Upstairs, in Carlton.

“There’s a saying in Japanese, ‘umi no sachi’, meaning ‘treasures of the sea’,” Reinantha tells Broadsheet. “Sachi also means ‘joy’ – it’s at the core of the restaurant’s philosophy.”

The new pop-up is a joint effort between Reinantha, who is currently jack-of-all-trades (“I’m front of house, back of house, bookkeeper, marketing, customer service – I do it all”), and chefs Jin Oon (who worked with Reinantha at Kisume) and Ida Bagus Palguna (ex-Cumulus).

Both Oon and Palguna bring fine-dining backgrounds to the table, but they share Reinantha’s vision of providing an accessible, casual setting for high-quality seafood and sushi. “I’m so inspired by how simple and casual sushi and sashimi restaurant culture is in Japan,” Reinantha says. “I want to bring that to Melbourne.”

After a successful residency at Leonie, Sachi is now in the former Shizuku Ramen space on Burwood Road, Hawthorn. It’ll stay there until October, when the team moves to a more permanent restaurant space at 179 Queen Street in the CBD, with plans for a walk-up sushi bar.

Chirashi don remains at the core of the menu: bowls of vinegar-seasoned rice with thick slabs of sashimi arranged flower-like around a cured egg-yolk heart. It’s served with seasonal tsukemono (pickles) and nori, and patrons are invited to sip a fish bone soup alongside their meal.

Beyond sushi and chirashi don, the Hawthorn pop-up also offers marlin burgers with spring onion relish, ocean trout katsu, and grilled swordfish topped with Yarra Valley caviar. The expanded menu also includes a sushi and sashimi omakase option for $150 per person.

Inspired by Leonie Upstairs – and his new friendship with Leonie’s venue manager, Sean Then – the drinks menu at the Hawthorn pop-up contains some premium bottles. Sake from producers like Noguchi Naohiko and Banjo Jozo sits alongside green tea umeshu, yuzushu and Japanese beers including Yoyogi pale ale and Kirin craft lager.
