# How do I choose a Japanese vacuum bottle? Thermos, Zojirushi or Tiger, which is best?

> All three are long-established Japanese brands with similar heat retention, so choosing by use matters more than choosing by brand. For commuting, pick a 500mL one-touch or screw-top mug (about 200g); for easy cleaning, look for 食洗機対応 (dishwasher safe) and lids with built-in gaskets (Zojirushi's seamless lid, Tiger's integrated-gasket lid); for winter hiking, get the Thermos mountain bottle (山専用ボトル) with a cup. As of October 2026, the lowest prices on Kakaku.com for mainstream 500mL models are mostly 2,200–3,300 yen, and since a vacuum bottle isn't an electrical appliance, you can carry it on or check it.

## Start with the lid type

| Type | Japanese | Best for | Example models |
| --- | --- | --- | --- |
| One-touch flip lid | ワンタッチ | Commuting, drinking on the go | Thermos JNL-S501, Zojirushi SM-VB60, Peacock AKT-50 |
| Screw-top | スクリュー | Less likely to open by accident in a bag | Thermos JOQ-481, Zojirushi SM-ZB48, Tiger MMZ-W050 |
| With cup | コップ付き | Hiking, pouring and sharing | Thermos FFX-902 |
| Food jar / lunch jar | スープジャー／ランチジャー | Soup and meals | Zojirushi SW-LA40, SL-NC09 |

## Comparing heat retention

Look for "保温効力（6時間）" (heat retention, 6 hours) on the official site or packaging: it's the water temperature after the bottle is filled with 95°C water and left for 6 hours. Under the same test, a higher number means better retention. For example, Thermos JNL-S501 (0.5L) is rated 68°C or higher, the screw-top JOQ-481 (0.48L) 71°C or higher, and the hiking FFX-902 (0.9L) 80°C or higher. Larger bottles generally keep heat better, and one-touch models usually score slightly lower than screw-tops of the same size.

## Small differences between brands (for reference)

- **Thermos**: many models and many lightweight options; its mountain bottle is well regarded among hikers.
- **Zojirushi**: features the "seamless lid" (シームレスせん), with the lid and gasket built as one piece so you don't remove the gasket to wash it; on some new models every part is dishwasher safe.
- **Tiger**: the MMZ-W series focuses on light weight (0.5L at about 190g), with an integrated gasket lid and dishwasher-safe parts.
- **Peacock (ピーコック)**: a long-standing budget Japanese brand; its lowest price on Kakaku.com is often around 1,500 yen.

The number at the end of most model names is the capacity; SM-ZB48, for example, is 0.48L. Many series also come in limited colors, so double-check the model and capacity before buying.

## Where to buy and how to take it home

Electronics chains in Tokyo such as Bic Camera and Yodobashi, plus LOFT and Hands (formerly Tokyu Hands), usually have a whole wall of vacuum bottles; see [Where to shop in Tokyo](/en/q/where-to-buy-tokyo/). A vacuum bottle isn't an electrical appliance and has no battery, so you can carry it on or check it, but empty it before security. From November 1, 2026, tax-free shopping changes to paying tax first and getting a refund later; see [Japan's new tax-free rules](/en/q/tax-free-2026/).

Compare specific models and prices on the [vacuum bottle category page](/en/c/thermos/), or use the buying guide to filter by use and budget.
