iroha by TENGA: Models, Differences, and How to Choose One

iroha is a Japanese line of vibrators and pleasure items designed for women and people with vulvas. It is made by TENGA, the company behind the well-known men's products, but it has its own design language: soft, rounded shapes, pastel and traditional Japanese colors, and names taken from nature and tea culture. This guide explains each current model, how they differ in shape, power, and battery type, and what the manufacturer says about water, lube, and cleaning. All product details come from iroha's official websites and FAQs.

What iroha is

TENGA launched iroha on March 3, 2013, after about three years of development (TENGA corporate history). The company says the goal was to make items "women can use for themselves, with peace of mind," at a time when most products on the market were designed for men to use on women. iroha uses the term "self-pleasure" and presents it as part of self-care.

In the US, iroha has its own official store (usstore.iroha.com). It lists the following series: iroha, iroha+, iroha mai, iroha TSUKI, iroha stick, iroha temari, iroha RIN, iroha koharu, iroha zen, iroha mini, and iroha petit, plus intimate-care products and accessories.

External models: iroha, iroha+, temari, zen, stick, mini

iroha (YUKI, MIDORI, SAKURA). These are the brand's signature palm-sized vibrators, covered in what iroha calls "Soft-Touch" silicone. The Japanese site describes YUKI as a snowman shape whose tip can also be inserted, MIDORI as a round shape you press against the body or use by its tip, and SAKURA as a split tip that can gently "pinch." The renewed version uses one button, has a quiet motor, and charges by sitting on a charging terminal. The listed body weight is about 88–100 g (about 3–3.5 oz).

iroha+ (TORI, KUSHI, YORU). The US store describes iroha+ as keeping the soft silicone while offering stronger vibration and "more defined edges," with five strengths and three pulse patterns.

iroha temari. iroha says temari has the most powerful motor in the series and a housing designed to reduce how much vibration reaches your hand, so it is less tiring to hold. It has four strength levels and two rhythm patterns. The body is silicone.

iroha zen. A battery-powered stick with soft, pleated ridges, designed for touching, tracing, and twisting. iroha's FAQ lists four modes: low, medium, high, and pulse.

iroha stick and iroha mini. These are the budget, travel-sized options. The stick looks like a lipstick, weighs about 44 g (1.6 oz), and adjusts with a dial. The mini fits in a palm and has one speed and one pattern. Note that the Japanese spec sheet lists the mini's material as elastomer and ABS plastic, not silicone, which matters for cleaning (see below).

Insertable models: koharu, RIN, TSUKI, mai

iroha koharu. iroha calls this its slimmest insertable item, "as slim as a single finger." The official size is 22 mm wide and 160 mm long (about 0.9 × 6.3 in), with a flexible bud-shaped head. It is designed for people who feel nervous about insertion and want to start small.

iroha RIN. A stick shape with a soft, round tip about 30 mm (1.2 in) across. iroha's FAQ explains that the RIN and the zen are both battery-powered, but the RIN's spherical tip is designed for insertion.

iroha TSUKI. In Japan this model is sold as "iroha FIT"; the product codes match. It has a bendable tip, eight modes (five strengths and three rhythms), and a case that both stores and charges it over USB-C. MIKAZUKI is narrower and tapered; MINAMO has a thicker, wavy shape.

iroha mai. The premium model. iroha says it uses "HapticWave" technology that converts 40–70 Hz sound waves into vibration, aiming for a deeper, more three-dimensional feel than a standard motor. It has ten patterns, each with three strength levels.

iroha petit: the single-use option

iroha petit is unusual: it does not vibrate and is not insertable. It is a small, soft shape made of 98% water (with agar) on a plastic handle, designed to be held against the body once and then thrown away. iroha says you can cool it in the refrigerator or warm it in bath water, but not in a microwave or freezer. It has a faint yuzu and ylang-ylang scent. Unopened, iroha says it keeps for three years from manufacture. It is a low-cost way to try something new without committing to a device.

Water resistance: what "up to 20 inches" means

Current iroha models are rated waterproof to a depth of 50 cm (about 20 inches). That means you can rinse them under the tap and use them in the bath or shower. iroha's FAQs add two cautions: do not expose them to strong water currents or deeper water, and remember that using a toy in bath water exposes your body to that water, so make sure the bath is clean.

Older models matter here. The FAQ for the original 2011 iroha (YUKI, MIDORI, SAKURA) says those versions were water-resistant but "not submersible" and should not be used in the bath. If you have an older iroha, check its manual before putting it in water.

Based on iroha's official FAQs. The drawing is simplified; follow your own model's manual.

Lube compatibility

iroha is clear on this point. Its FAQ says to use "ONLY water-based lubricants" and warns that silicone-based lubricants, massage oil, and baby oil may discolor or deform the product. This matches independent guidance: a 2025 review in Canadian Family Physician notes that silicone-based lubricants can degrade silicone devices, including sex toys, while water-based lubricants are compatible with all common materials (Vanderschee and Kostov, 2025).

If you are prone to irritation or vaginal infections, the same review suggests avoiding lubricants that contain glycols (such as glycerin), parabens, fragrance, flavors, or warming and numbing agents. See our lube guide for how to read a label.

Cleaning and storage

iroha's FAQs give the same routine across models:

Wash with cold or tepid water. Use a mild, neutral soap for a deeper clean.
Do not boil the item or leave it soaking in cleaning products.
Do not use alcohol or strongly acidic or alkaline cleaners. If you use a toy cleaner, make sure it contains no alcohol.
Dry fully before storing. Several models include a cap, lid, or case for storage.

iroha also sells its own ITEM CLEANER, which it describes as a wipe-off cleanser that needs no rinsing. Silicone is non-porous, which makes it easier to keep clean than porous materials, according to clinical guidance on sexual devices (Judge, NEJM Journal Watch, 2019). The elastomer used in the iroha mini deserves extra care: wash it promptly and dry it completely.

How to choose

Just curious, small budget: iroha petit or iroha stick.
Want a soft, quiet external vibrator for regular use: iroha (YUKI, MIDORI, or SAKURA), or iroha+ if you prefer stronger vibration.
Want power without hand fatigue: iroha temari.
Curious about insertion but nervous: iroha koharu first, then RIN or TSUKI.
Prefer not to deal with batteries: any rechargeable model (iroha, iroha+, temari, TSUKI, mai).
Traveling often: stick, mini, or koharu, since they run on a single AAA battery.

You can compare current models on the official iroha US store or the iroha brand site.

If insertion is painful, stop. Pain during sex or insertion is common, and the Canadian Family Physician review notes that about two-thirds of women experience it at some point in their lives. It is also treatable. If it keeps happening, or you notice bleeding, unusual discharge, or itching, talk to a gynecologist or primary care provider.
