Princess-Style Studio 'Tiarina' Opens Two New Locations in Shin-Okubo and Machida for 'Oshikatsu' Self-Photography

Osara Rock Co., Ltd. (Headquarters: Saitama City, Saitama Prefecture; Representative: Daisuke Kikuta) simultaneously opened new locations of 'Tiarina,' a princess-style self-photo studio specializing in 'Oshikatsu' (idol/character support), birthday festivals, cosplay, and portrait photography, in Shin-Okubo and Machida in May 2026. Following the Akihabara and Kita-Senju stores, these mark the 3rd and 4th locations, establishing a 4-store system in the Tokyo metropolitan area. Official Website: https://tiarina.jp/

Expansion of 'Oshikatsu Self-Photo' Demand to Terminal Station Areas

Centered around Generation Z, the culture of preserving time spent with 'Oshi' (favorites) in photos and videos on social media is no longer a passing trend but has taken root as a lifestyle culture.

Demand for 'self-photography'—which can be completed near stations, with small groups, and in a short time without using large-scale equipment or professional photographers—continues to grow steadily for birthday parties without the person, birthday festivals, altar photography, and cosplay.

The Akihabara and Kita-Senju stores, which opened in October 2025, have been highly patronized by many customers.

The new Shin-Okubo and Machida stores represent the first step in a "horizontal rollout" based on this track record.

By simultaneously securing two areas on the routes of Oshikatsu users—Shin-Okubo, the mecca of K-POP and Korean culture, and Machida, a terminal station gathering access from the Kanagawa Prefecture side—they aim to deliver a state where 'Tiarina is at the nearest station' to even more customers.

Tiarina Photo Studio Shin-Okubo Store

Tiarina Shin-Okubo Store

About a 4-minute walk from Shin-Okubo Station, the mecca of K-POP. It is a prime location with a convenience store a 1-minute walk away and Don Quijote a 5-minute walk away, making shopping before and after Oshikatsu activities hassle-free.

[Studio Overview]

Location: Approx. 4 minutes on foot from JR 'Shin-Okubo' Station / 1 minute on foot to convenience store

Size: Approx. 20㎡ (1st floor)

Concept: A compact princess-style space based on white

Facilities: Spacious area with a ceiling height of 3.4m / High-performance projector / Large LED ring light / Video light / Full-length mirror / Dresser / Toilet with bidet

Photography Props: White, black, and light blue artificial flowers, tiaras, candle stands, photo frames, and many others

Usage Scenes: Birthday parties without the person, birthday festivals, altar photography, portraits, cosplay, video shooting for social media, etc.

[Key Points of the Shin-Okubo Store]

Because it is a 1st-floor room, bringing in large items like cakes and balloons is smooth.

The compact space makes it easy to organize altars and photo sets, designed to be 'photogenic' without creating empty spaces in the frame even when shooting from a distance.

The newly built, clean interior offers a generous ceiling height of 3.4m, which pairs perfectly with princess-style props.

Tiarina Machida Store

Tiarina Machida Store

A 2-minute walk from Machida Station, one of the largest terminal stations in the Kanagawa area where the Odakyu Line and JR Yokohama Line intersect.

It is a strategic location capturing the movement of Oshikatsu users from within Kanagawa Prefecture and the Tama area.

[Studio Overview]

Location: Approx. 2 minutes on foot from 'Machida' Station

Size: Approx. 30㎡ - Capacity: Up to 6 people

Concept: A bright princess-style space based on white

Facilities: Projector / LED ring light / Video light / Numerous photography props / Fully equipped with Wi-Fi

[Key Points of the Machida Store]

At approximately 30㎡, it is slightly larger than the Shin-Okubo store.

Capable of accommodating up to 6 people, it can handle slightly larger-scale events such as birthday festivals among friends, twin coordinate photography, and multi-person altar setups.

This store opening responds to customer feedback noting that 'there are few full-fledged Oshikatsu studios in the Kanagawa area.'

Open Commemoration Campaign Running Until the End of May

Shin-Okubo Campaign Machida Campaign

To commemorate the opening of the Shin-Okubo and Machida stores, an 'OPEN Commemoration Campaign' featuring special pricing and free use of photography equipment is currently underway at both locations until the end of May 2026.

Future Developments

Osara Rock Co., Ltd. positions Tiarina's format of 'small-scale, near-station, princess-style' as a 'reproducible unit for Oshikatsu self-photography,' and will accelerate multi-store expansion primarily around major terminal stations in the Tokyo metropolitan area.

Seasonal theme decorations, collaborative projects, and expansion into new areas are also planned in sequence.
