Restaurant in Mosman Park, Australia
Two formats, 20 years, one booking.

Tsunami has run from 20 Glyde St in Mosman Park for over 20 years and holds a World of Fine Wine 2-Star Accreditation — a real signal in a suburb not known for serious drinks programs. The dual format of Izakaya dining and teppanyaki bar makes it the strongest option in the area for a date or celebration dinner. Book one to two weeks ahead for weekends; request the garden from October through April.
Tsunami has been earning its place at 20 Glyde St for over 20 years, and the World of Fine Wine 2-Star Accreditation confirms this is not a restaurant coasting on longevity. For a special occasion dinner in the western suburbs of Perth, it is one of the few venues in the area where the food, the drinks list, and the atmosphere are all working in the same direction. Book it for a date, an anniversary, or any meal where the setting needs to do some work. If you are looking for a casual weeknight feed, you can find cheaper and easier options elsewhere in Mosman Park.
Tsunami runs two distinct formats under one roof: Tsunami Izakaya, a Japanese fusion dining room, and Tsunami Ko, a teppanyaki bar where the cooking happens in front of you. The teppanyaki format is the stronger choice for groups and celebrations — the theatre of the grill gives the meal a natural energy that a static dining room cannot replicate, and it tends to suit larger tables without the awkwardness of a shared menu. The Izakaya side suits couples or smaller groups who want a quieter, more composed experience.
The drinks program is a genuine differentiator here. The venue has accumulated a wine, sake, and whisky list sourced specifically to complement Japanese cuisine, and the World of Fine Wine accreditation is a direct signal that the list has been vetted by people who know what they are looking at. For most Perth restaurants at this tier, the drinks list is an afterthought. At Tsunami, it is part of the proposition. If you are coming for the sake pairing or want to explore Japanese whisky alongside your meal, this is one of the few places in Perth's western suburbs where that conversation is worth having with the staff.
The garden setting — sheltered by vines, lit by fairy lights , is the room to request for a date or anniversary dinner. It reads as deliberately romantic without tipping into theme-park territory. Inside, the walls stocked with bottles create a warm, cellar-like atmosphere. Both rooms work for a special occasion; the garden is the better call in the warmer months, roughly October through April, when Perth evenings are warm enough to sit outside comfortably.
Service at a 20-year-old independent venue in a suburban Perth location can go either way: deeply experienced or complacent. The fact that Tsunami is still earning external accreditation after two decades suggests the kitchen and floor have not settled. The drinks accreditation in particular requires ongoing curation, which is a staffing and management commitment, not just a historical achievement. That said, specific service claims beyond what the data supports are not something Pearl will make here , what you can reasonably expect is a team that knows the menu and the drinks list well enough to guide you through both.
Booking at Tsunami is direct. It is not a 6-week wait, and it does not require a credit card hold or a waitlist. For a weekend dinner , especially Friday and Saturday evenings , book at least a week ahead to secure the garden or a teppanyaki table. Midweek bookings are easier to arrange on shorter notice. The teppanyaki bar seats are worth requesting specifically when you book; they tend to fill before the main dining room on busy nights.
Optimal timing: aim for an October-to-April evening booking if you want the garden. For the teppanyaki experience, a weekend sitting gives the format more energy , a half-empty teppanyaki bar on a Tuesday is a different experience than a full one on a Saturday.

What to weigh when choosing between Tsunami and alternatives.
Yes, and it is better suited to occasions than most Japanese restaurants in the Perth metro area. The teppanyaki format at Tsunami Ko delivers a live-cooking show element that makes it a natural fit for birthdays or anniversaries. The izakaya side is more intimate, lined with wine, sake, and whisky. The World of Fine Wine 2-Star Accreditation signals the drinks list is taken seriously, which matters when you are spending on a celebration dinner.
The venue has a teppanyaki bar at Tsunami Ko where seating is arranged around the cooking surface — that is the closest equivalent to bar dining here. It works well for solo guests or pairs who want an interactive format rather than a standard table. The izakaya side is a separate dining room rather than a bar-seating setup.
Yes. The two-venue format at 20 Glyde St makes Tsunami one of the more practical options for groups in Mosman Park. Teppanyaki at Tsunami Ko works well for parties of six or more who want a shared, theatrical format. For larger groups that want a more relaxed pace, the izakaya dining room is the better fit.
Mosman Park does not have a deep bench of comparable Japanese restaurants at this level. For a broader fine-dining comparison in Western Australia, Rockpool in Perth is the obvious alternative if you want a more formal, high-spend evening. For something more casual and neighbourhood-focused, local Perth suburbs like Subiaco and Fremantle have izakaya-style options, though none carry the same 20-year track record or World of Fine Wine accreditation that Tsunami holds.
A week or two is generally enough for most weeknights and many weekends. This is not a six-week wait situation. For a Friday or Saturday teppanyaki booking, particularly for a group, give yourself two to three weeks. The garden seating fills faster in warmer months, so book ahead if that is a priority.
The setting, with a wine-lined dining room and a garden lit by fairy lights, reads as smart casual territory. Teppanyaki at Tsunami Ko has the same relaxed-but-considered tone. There is no indication from the venue of a formal dress requirement, so neat casual is appropriate. Avoid beach or activewear.
The teppanyaki bar at Tsunami Ko is the stronger solo option: counter seating, a live-cooking format, and a natural conversation anchor if you want it. Solo diners in the izakaya room are accommodated, but the format is more table-oriented. For solo dining with a drinks focus, the sake and whisky selection gives you something to work through at your own pace.
Keep this venue in your Pearl passport, rate it after you visit, and track it alongside every other place you collect.
