湯治

• Reading: とうじ
• Romaji: tōji
• Kanji breakdown: 湯 (hot water) + 治 (cure/heal) → hot spring cure
• Pronunciation: /toː.dʑi/

Meaning

Hot spring cure — an extended stay at an onsen for health and healing purposes.

An ancient Japanese practice of staying at a hot spring for days or weeks to treat ailments and recover health. Traditional 湯治 involves a disciplined bathing regimen rather than just relaxing. While the old-style weeks-long stays have declined, the concept has evolved into modern 'プチ湯治' (petit tōji) — shorter 2-3 day health-focused onsen stays. Still practised seriously in some regions, especially Tōhoku.

Examples

1. おばあちゃんが毎年東北の温泉に湯治に行く。 My grandma goes to a Tōhoku onsen for a hot spring cure every year.
2. プチ湯治ってやつで2泊3日温泉に浸かりまくった。 I did what they call a 'petit tōji' — soaked in the hot springs for two nights and three days straight.
3. 湯治場ってひなびた雰囲気があって落ち着くんだよね。 Tōji spots have this rustic, old-timey vibe that's really calming.

Usage Guide

Context: travel, health, traditional culture

Tone: health-conscious, traditional

Do Say

• 肌荒れひどいから湯治に行きたい。 (My skin is so rough, I want to go for a hot spring cure.)
• 昔の人は農閑期に湯治に行ったんだって。 (Apparently people in the old days would go for onsen cures during the farming off-season.)

Don't Say

• 友達とワイワイ温泉に行くのを「湯治」とは言わない — 湯治は健康目的の滞在 (A fun onsen trip with friends isn't 'tōji' — tōji specifically means a health-focused stay)

Common Mistakes

• Pronouncing it as ゆじ instead of とうじ — the correct reading is とうじ
• Thinking 湯治 is the same as a normal onsen vacation — it specifically implies therapeutic, health-focused bathing over multiple days
